Root Canal Vs Extraction and Implant: Which to choose

The most frequent causes of tooth damage are due to already broken teeth by any accident and infections or plaques. Cavities are the major cause of tooth decay that causes holes in the enamel, which is the hard outer covering of the tooth. Root canal is particularly done to save the badly damaged tooth due to infection, as a replacement for extraction. A root canal is done by a root canal specialist or endodontist and the procedure is known as endodontic treatment. It is needed if the middle part of the pulp inside the tooth that consists of all the blood vessels and nerves is infected and causes inflammation. Together, all these factors contribute to tooth damage that can lead to pulp decay, and inflammation then affects the nerves supplying blood, causing severe pain.

The Signs That a Root Canal Is Needed are:

  • Stabbing pain while chewing or biting 
  • Sensitivity on eating hot or cold
  • Pimples on gums
  • Cracked teeth with inflammation
  • Swollen and painful gums
  • Deep tooth decay with damaged gums

1. Root canal VS extraction and implants:

An infection in the pulp of the tooth causes the nerve inside to get irritated and cause severe pain. The extraction of the same tooth and the infected tissue, and the nerve helps relieve the pain. Risks of extraction are more severe than with root canal therapy. 

The risks of tooth extraction are:

  • Loss of bone mass and volume on which the extracted tooth laid.
  • Nearby teeth might position out of place with time, causing misalignment of the teeth.
  • Creating a vacant space in the jaw causing lodging of food, leading to cavity formation.
  • Risk of loss of neighboring teeth is increased. 

Root canal treatment is a conservative and non-painful procedure, unlike the misconceptions. This procedure helps clean out all the damaged tissue and nerve from inside the tooth. A special material known as gutta-percha is used to fill inside the outer covering of the tooth. No medical procedure can be completely risk-free and hence root canal procedure also has its own risks, which are:

  • Complete removal of the infection from inside the tooth is not possible at times which may need endodontic treatment.
  • A crown good in quality is needed to cover the root canal-treated tooth, as the root canal procedure weakens the tooth and makes it susceptible to fractures.
  • A good quality crown and root canal procedure can be expensive at times.
  • Few research says that root canal treatment can cause systemic illness due to the nerve affected, but this theory is not complete and does not have enough evidence yet.
  • The tooth may be too damaged for the procedure, and the dentist may know that the damage is too severe, and the tooth cannot be saved after the whole procedure is done.
  • Severe complications like abscess formation can lead to tooth extraction.
  • Procedure of Root Canal Treatment

Firstly, an X-ray of the tooth is done to determine the pulp chamber, and then a local anesthetic is administered to avoid pain to the patient. A rubber sheet is placed to avoid and saliva from the surrounding. Then the crown is drilled to expose the pulp chamber and remove all the diseased and infected pulp from inside the tooth, the created space is disinfected and filled with gutta-percha and then covered with dental cement to seal the tooth. The seal is then shaped by an irrigation method, after which the tooth is covered with a crown and is cemented in place to avoid displacement and provide longevity to the tooth. Root canal procedure is successful with a rate of 95%, and the treated tooth can usually last for a lifetime. 

2. When does a dentist suggest Root canal treatment?

Inflammation in the tooth or abscess beneath can progress into a major infection and lead to complete loss of function if not treated timely. Hence root canal procedure came into action to retain the function and outer appearance of the tooth. It also prevents the neighboring tooth from damage and excessive strain, as in the case of tooth extraction.

The techniques have advanced now that the patient no longer experiences major pain due to the use of local anesthetic as they numb the nearby area. The use of an anesthetic helps ease the pain caused by inflammation and helps carry out the procedure with relative ease.

Post-treatment guidelines after a root canal procedure include:

  • Eating anything just after the procedure is not advisable as the area is numb and may lead to accidental nipping of the tongue. It is advised to stay on fluids until the numbness goes away.
  • Consumption of antibiotics as directed by the doctor.
  • Maintenance of oral hygiene with frequent cleaning and teeth flossing is essential after root canal treatment.
  • Hard and crunchy stuff is advised not to be consumed few days as it can lead to displacement or damage to the crown. 
  • The temporary filling on the teeth needs to be weared off for the crown to be placed perfectly, but if the filling wears off completely, it needs to be done again to place the crown.
  • Until the procedure is complete with a permanent filling or crown, it is advised to avoid chewing with the tooth and prevent the fragile tooth from breaking before it can be fully restored.
  • It generally takes a week to recover from the procedure entirely.

3. When does a dentist suggest Extraction and Implant?

Because of the following reasons, extraction maybe advised by the dentist:

  1. Severe Damage or Tooth Decay– When the bacteria spread into the soft tissue of the tooth, to the dental pulp. The pulp consists of connective tissue and blood vessels and causes severe pain, inflammation, and infection. If the root canal infection is left unaddressed at this stage, it leads to abscess formation. Abscess formation can cause excruciating pain, and the infection can reach the ear, jawbone, or even brain under extreme conditions, requiring tooth extraction.
  1. Gum Disease – This disease is caused by infection of the gums and may lead to tooth extraction as it reaches roots and the alveolar bone. The most common cause is bacterial built-up or plaque that leads to tooth infection and later extraction if left untreated.
  1.  Affected Wisdom Tooth – If a wisdom tooth is affected or blocked from coming out. To prevent the risk of an infection that may lead to gum disease for such teeth extraction is recommended.
  1. Teeth Overcrowding- It is a common problem in females as their jaws are smaller than males. Overcrowding causes difficulty in eating, even in speech, due to lack of space. Hence extraction is needed to realign the teeth.
  1. Accident or Injury- If the tooth has undergone damage due to an accident or injury, the dentist would advise extraction as preserving the teeth would be very expensive and time-consuming.  

Dental implants are the top option for tooth backup due to the following reasons:

  • These dental implants are made to last for a lifetime and do not need any changes.
  • They have a success rate of 95%, showing how successfully these implants can bond to the patient’s jawbone. 
  • Implants imitate a natural tooth.
  • Implants also protect from the shrinking of the jawbone after tooth extraction.
  • It also provides a perfect base for the placement of the crown.
  • One can consume anything according to their will without the risk of moving, sliding, or breaking.


Therefore it is advisable to contact a Dentist when suffering from tooth or gum ache and get a checkup done at first. This will help to address the root cause of the issue at first and avoid any further complications. At Orion, you’ll get the best suggestion and treatment as per your concern.


  1. Root canal vs. Implant

If the tooth has major decay and you’re ready for a high cost treatment then one may go for an implant for the long term. But if the person prefers to keep their own tooth with the risks, a root canal can be cost effective and less invasive.

How Long Do Braces take? Duration & more

If you are planning to get braces to straighten your teeth, it’s very obvious to have hundreds of doubts in your mind. The first and foremost is, how long will the braces treatment last? That way, you will know how much time commitment you will need, how many appointments you will have, and most importantly, how long will the braces take to work before you can have that dream smile of yours. This mainly involves wearing braces for a considerable long time, which varies based on your treatment needs, types of braces or aligners, and your behavior towards the treatment. Meticulously follow your orthodontist’s advice and maintain healthy oral habits to maximize the effectiveness of your orthodontic treatment and minimize the time period.

We, through this article, will walk you through the basics of how the orthodontic treatment works, how long the braces take, and tips to minimize this time and speed up your results.

Feel free to skip ahead if one topic catches your eye:

1.     How Do Braces Work?

2.      How long do braces take?

3.      Can I Get Results Faster?


1.  How Do Braces Work?

It is essential to understand how the dental braces work before you know the time they will be worn. Braces work by slowly and gradually moving the teeth and surrounding structures in a required direction and position in a planned and controlled manner. Orthodontic procedures require very careful manipulation of force which guides the teeth’ movement in a predictable pattern. This results in changes in teeth position, bone, and ligaments in your mouth, which need to be made steadily and not suddenly, as too much pressure can cause harm to the teeth, bone, and gums. There are different types of dental braces, such as metal, lingual, invisible, self-ligating, clear aligner trays, etc., that have different components but work on this same principle.

  • Once the braces or aligners are fitted onto your teeth, you will need to regularly follow up with your orthodontist after a few weeks for the assessment to know if your treatment is working in the right direction and accordingly tightening of the braces, or changing of trays (in case of in aligners) will be done.
  • This process will continue till the end of the treatment.
  • After completing your treatment, you will need to wear retainers to maintain the movement thus made through the treatment.

2. How long do braces take?

As soon as you start wearing your braces, they pull your teeth and other structures in the right direction. The average time required for completion of your orthodontic treatment ranges from 6 months to 18 months but is different for each individual and the time frame may increase in very severe malignment cases. This depends on several factors:

  • The severity of your misalignment issue: Depending upon how severe your dental malalignment problem is, your orthodontic treatment time will vary accordingly.
  • The type of teeth braces used: various types of orthodontic braces may require a different amount of time to correct your problems.
  • Age: At what age you are getting the braces greatly impacts the time taken for the treatment. Misalignment issues treated in children and teens usually take a much shorter time than the same treatment in adults. The bones become denser and more difficult to move as age progresses than soft and porous bones in children.
  • If other treatment modalities or devices are required: Sometimes, for a successful orthodontic treatment, other treatment modalities like the creation of space or jaw alignment are also needed, and other procedures and devices are used along with braces like tooth extractions spacers, headgear, rubber bands, etc. These significantly alter the time of treatment completion.
  • Your adherence to doctor’s instructions: Depending on how meticulously you follow your orthodontist’s instructions, maintain oral hygiene by properly brushing and flossing, follow diet instructions, and regularly attend follow-up visits will significantly affect the treatment time. The better you follow all instructions, the fewer chances of tooth decay or wire breakage, and hence quicker the results will be.

 3. Can I Get Results Faster?

You can follow these tips to minimize your time for the completion of your treatment:

Always follow your orthodontist’s instructions properly.

  • Be careful about what you eat:
  • Avoid carbonated drinks and sodas, which can damage your teeth.
  • Stay away from sugary and sticky foods like gums, caramels, candies, etc. They will stick on the teeth braces or brackets, increasing the risk of tooth decay and preventing them from working well.
  • Do not bite on hard foods like apples, hard candies, raw vegetables, chips, popcorn, etc. Always break them into small pieces before you eat. This will avoid the breaking of wires and save time for their repair.
  • Do not bite or chew on anything other than food like chewing on pencils, biting nails, etc., to avoid damaging your wires.
  • Take very good care of your braces:
  • Proper brushing, flossing, and rinsing to keep your teeth and mouth clean will prevent plaque build-up between teeth and gums. This will allow the braces to work properly, thus enabling faster tooth movement for quicker results.
  • Never try to fix broken teeth braces yourself, but visit your orthodontist immediately.
  • Always follow your doctor’s instructions religiously:
  • Like wearing bands and maintaining oral hygiene and regular follow-ups, etc. This will help to achieve your results quickly.


1.  How long do braces take to close a gap?

Small gap closure may take around 3-4 months while correction involving generalized space reduction or bite correction will take longer, about 1-2 years. The entire alignment of all your teeth will need to be balanced. In case any gum tissue is present between,  two teeth, then that will need to be removed to sustain the gap closure.

2.  Why do braces take so long?

The teeth are attached to the gums and jaw bone. Therefore, along with the underlying structures, they have to be moved slowly and gradually with a controlled pressure to achieve desirable results. Too much pressure for too fast movement may be very harmful and cause injury and damage to the teeth and jaw bone.

Cavities:Causes,Symptoms and Treatment

Are you suffering from discomfort, sensitivity, or pain just after having a bite of ice cream or a sip of coffee? Are you also experiencing a dull or sharp pain in or around your tooth? There may be chances of a tooth cavity.  Do not worry,  oral cavities are becoming quite common, especially in children, teenagers, older adults, and even infants. It can be prevented by early detection and managed with timely dental treatments.

Our tooth is made up of three layers: the outer layer: enamel, the second layer: dentin, and the innermost layer which houses nerves and blood vessels in the pulp. Damage or decay of these layers of the tooth causes cavities. It can be reversed back by proper brushing and flossing if the cavity has just started and is limited to the enamel but after it reaches the dentine and pulp, it has to be treated and cannot be reversed. Scroll ahead to know more about tooth caries, their symptoms, causes, and most importantly how you can prevent them.

  5. FAQs


1. What are cavities?

Cavities, also called dental caries, are permanently damaged areas on the surface of your tooth. The decay begins with the destruction of the enamel by acids produced by bacteria causing its erosion and resulting in small pits and holes with blackening of the surface. As it progresses, the pits enlarge in size and the decay reaches the deeper layers, and you will start feeling discomfort or pain. Untreated dental cavities can lead to severe toothache, and infection and you may even lose your teeth.

2. Signs and Symptoms of Cavities.

 The signs and symptoms of cavities depend upon the extent and it’s location and vary accordingly. When the cavity just begins to form, you usually don’t feel any pain or discomfort. As it progresses, some early signs and symptoms are:

  • General tooth sensitivity: Mild sensitivity felt while eating/ drinking cold or hot.
  • Discoloration: White and dark spots on the tooth surface will be seen.
  • Holes and pits in the teeth: Small holes are formed due to erosion of the tooth surface. During a checkup, the dentist will feel a catch with the diagnostic probe.
  • Bad breath: Due to plaque accumulations, full of bacteria, a foul smell from the mouth may be there.
  • Food frequently trapped in or between the teeth: Due to pit formation, the food particles may be seen trapped in those areas on the tooth surface or in between two teeth.
  •  Occasional dull tooth pain: At times you may feel mild dull diffuse pain around the area of the developing tooth cavity. 

When it is left unmanaged, the dental cavities may result in serious signs and symptoms:

  • Toothache:  This can spontaneously occur without any apparent cause or maybe constant.
  • Sharp pain when eating or drinking, sweet, hot, or cold: Severe sharp pain may be felt with sweet, hot, and cold food and drinks.
  • Pain while biting on food: There may be difficulty in eating food because of severe pain while applying pressure on the tooth.
  • Severe pain, swelling of the face, and fever due to pus formation: At times due to infection, pus formation with severe throbbing pain with swelling in gums, or jaw, foul taste in the mouth, pain radiating to the ear, jaw, and neck and fever may occur. Untreated infection may cause loss of jaw bone and ultimately loss of the tooth.

Contact your dentist immediately if any of these symptoms occur.

3. Reasons, you have cavities.

The formation of dental cavities by tooth decay is a slow process occurring over some time. It develops due to:

  • Plaque formation: Dental plaque is a sticky film coating your tooth surface, formed due to not brushing well and eating stickier and sweet foods. Bacteria feed and increase in number over residual food particles in your mouth resulting in plaque formation which, if still not removed hardens and forms calculus which is difficult to remove with brushing.
  • Acid attack by a plaque: The bacteria in the plaque produce acids that remove minerals from your teeth and thus erode the surface resulting in the formation of tiny openings in the enamel. Slowly the bacteria make their way through the inner layers of dentine and pulp.
  • Continuation of decay: As the bacteria reach the pulp and are still not treated, it causes irritation and swelling of the pulp tissue, resulting in severe pain. The damage may reach beyond the tooth root, to the bone causing serious infection.

You are at risk if:

  • You do not brush and floss properly and regularly.
  •  Have frequent snacks and aerated drinks.
  • Bedtime infant feeding and going to sleep without mouth cleaning.
  • You have a dry mouth.

4.  What are the best treatment options for Cavities?

 Early detection and timely treatment are the keys to prevent serious issues and pain. The cavities treatment depends upon the extent and the stage of your tooth cavities:

  • Professional fluoride treatments: if the cavity is at a very early stage, then this treatment can help it stop there and then. Regular brushing can help develop them again.
  • Cavity Fillings: This is the most common cavity treatment method to restore your tooth structure to its original form and function by fillings of different materials like metal, tooth-colored composite, porcelain, etc. 
  • Crowns: When the decay is extensive, a crown may be needed to replace your complete natural tooth crown. The dentist will need to remove some tooth structures to prepare them to receive the crowns.
  • Root Canal Treatment: When the cavity extends to the pulp, RCT is needed to remove the infected pulp and replace it with a filling.
  • Tooth Extractions: Sometimes, teeth become so severely damaged that there remains no chance for them to be restored and they need to be removed.

The cavity treatment cost varies according to the treatment done. At Orion, all treatments are very reasonable.

5. FAQs

1.  How will I know if I have cavities?

Cavities look like brown-yellowish spots in the initial stages, usually, they are not seen in between the teeth and do not cause any symptoms until they extend to deeper tooth layers. Therefore, regular dental check-ups are the only solution to detect a cavity at its early stage.

2.  How can I prevent developing cavities?

  • Brush and floss twice a day.
  • Avoid frequent snacking, and sugary and sticky foods.
  • Eat healthy nutritious meals.
  • Visit your dentist regularly.
  • Drink water frequently.

3.  Should we use fluoridated toothpaste for kids?

Fluorides prevent the development of cavities, but if ingested more than a certain amount may be harmful too. A pea-sized toothpaste is recommended but always take advice from your dentist before using them.

Dentures Vs. Implants: Pros & Cons

Are you considering the replacement of your missing teeth, but are confused between a variety of options available and wondering which can be the best for you? Then you are at the right spot, as we will, in this article, discuss the two most common tooth replacement options, i.e., Dentures and Implants, and weigh their pros and cons to get a fair idea of both.

Dentures are removable and made from porcelain, acrylic, metal, plastic, or their combination. There are different types of dentures made from a variety of materials:

  • Complete dentures: Which replace all your teeth.
  • Partial dentures: which replace some of your teeth to fill in the gaps between existing natural teeth.
  • Implant-supported dentures: These are sturdier as implants support them underneath the dentures.
  • Immediate dentures: These are temporary dentures worn immediately after tooth extraction until permanent ones are made.
  • Flexible dentures:  They are made from thermoplastics and are thin, bendable, and comfortable.

Dental Implants, on the other hand, are a permanent fixed teeth replacement option for your missing teeth. The different types of dental implants are:

  • Single tooth Implant: A single implant for an individual missing tooth.
  • Implant bridge: Two implants are used for more than two missing teeth.
  • All on 4 implants: Complete fixed or removable dentures can be placed on 4 or 6 implants. This gives stability and prevents further bone loss.
  • Endosteal implants: Which are placed inside the jawbone
  • Subperiosteal implants: A metal frame is placed on the jaw bone below the gums, instead of placing the implants inside the bone.

  4. FAQs


1. Pros and Cons of Dental Implants.

A dental implant is a fixture that is surgically put into your jawbone which fuses to the bone, and a crown is then placed above it, thus acting as the missing tooth.

  • Pros of Dental Implants:
  • Permanent and longevity: Implants usually last for a lifetime, if one maintains good oral hygiene, and visits dentists regularly.
  •  Very natural: The implants look and feel like your original natural teeth.
  •  Ease of care: You need to brush and floss like your natural teeth, making them easy to maintain.
  • No diet restrictions: you can eat all foods, even sticky and hard ones.
  • Perfect Speech: Dental implants allow natural speech as was before your tooth loss.
  • Preservation of jaw bone: Bones and surrounding structures have no risk of further deterioration. Future dental procedures are less likely needed.

Cons of Dental Implants

  •  Costly: They are expensive compared to dentures.
  • Invasive technique: It is a surgical technique with a lengthy healing process.
  • Long wait periods: There will be a 4-6 months waiting period after surgery before crowns can be placed onto the implants.

2. Pros and Cons of Dentures.

Dentures also provide numerous benefits for your looks, oral health, and functions.

 Pros of dentures:

  • Cost-effective method: Dentures are less costly than implants, making them an affordable treatment option.
  • Non-invasive procedure: No surgery is required for dentures, so all surgical risks are eliminated.
  • Ease of modification: If additional teeth are lost in the future, dentures can be easily modified to accommodate new artificial crowns.
  • Can be an option even with weak and unhealthy jawbones and gums: Since dentures rest over your gums, they can be made even if the jaw bone is minimal with not-so-healthy tissue.
  • Good option as a start: When teeth are removed recently, people feel easier to start with dentures to get used to artificial teeth, before they go for the expensive implants.
  • Serves as an intermediate solution: Since implants have a long wait period, the dentists usually give temporary dentures for that time so that your looks and functions can be maintained.

 Cons of dentures

  • Fit is not very proper: One of the major drawbacks of dentures is that they may slip while eating or speaking, which can be very embarrassing.
  • Not very aesthetic: Dentures do not look as natural as implants.
  • Diet restrictions: Some foods have to be avoided for denture wearers like hard nuts, sticky gums, popcorns, caramels, corn on the cob, etc.
  • Requires frequent replacement: The teeth wear off, and the fit becomes loose as the underlying jaw bone slowly decreases. It may also fall and break easily. On average, they need to be replaced every 3-6 years.
  • Thorough cleaning is required: you need to remove your dentures and clean with specialized tablets each night, which can be troublesome and expensive in the long run.
  • It May be harmful to the adjacent structures: Partial dentures weaken the adjacent surrounding teeth that support them.
  • Increased risk of gum disease: This may be due to food particles trapped by the dentures.
  • Prove to be expensive in the long run: Due to maintenance and replacement costs, it tends to be costlier in the long run. 


3. Dentures Vs. Implants: Which one to choose in your condition?

 Many considerations need to be kept in mind for knowing which can be good for you like:

  • Your jaw bone health.
  • The number of teeth to be replaced.
  • Cost of treatment.
  • Your oral habits.
  • Your own preferences etc.

Your dentist is the best person who can help and guide you to decide on the best option for you. But you may keep in mind that you can always start with dentures and gradually move on to implants if your dentist feels right for you, as dental implants are considered the standard of care for teeth replacement because of their longevity and convenience. Talk to your dentist, and together you can figure out the best for you.

4. FAQs

1.     What is the cost of dentures and implants in Delhi NCR?

Implants are definitely costlier than dentures initially, but in the long run, they may not seem expensive in the long run. On average, the cost of:

Single Implant is INR 15,000- INR 45000.

Full mouth denture is INR:17000-INR 23000

2.     How do dentures and implant-supported dentures differ?

Dentures are directly put on your jaw bone, and they are always removable, while implant-supported dentures will have 4 or 6 implants placed into your jaw bone and dentures then placed on them. This provides more stability, better fit, and no risk of further bone loss. These can be removable as well as fixed.

3.     Which can be better, dentures or implants, if I have a thin jaw bone?

Implants usually require sufficient bone for them to be placed onto the jaw. Therefore for a thin jaw bone, dentures may be a better option. Your dentist will assess and guide you on which can be the best option for you.

Root Canal Infections: Symptoms, Causes, Treatment, and Prevention

An infected and painful tooth often needs a Root Canal Treatment, for repairing the decayed or infected pulp tissue. The tooth has three layers- the outer hard part- the enamel, the middle layer which is a soft yellow structure- the dentin, and the pulp, which is the innermost layer of your tooth containing the blood vessels and the nerves which maintain the vitality of your tooth. It is present in the root of the tooth in a canal-like structure called the root canal.  The root canal treatment helps to remove the bacteria from your infected tooth and saves your natural tooth. It involves the removal of the decayed pulp, cleaning, filling, sealing the tooth, and finally preparing crowns for strengthening. Although considered a costly affair, given the benefits it provides, the root canal treatment cost is quite reasonable with a very high success rate of around 95%.  However, like all procedures, root canal-treated teeth may have a risk of reinfections. Nothing to get panicky about, these root canal infections may be treated well. Through this article, you will find all that you wish to know about root canal infections, their causes, the ways of treating them and how you can prevent them.

  5. FAQs


1. What are root canal infections?

Since a root canal-treated tooth has no pulp inside, we can say that it cannot be infected anymore, because the infection can happen only in living tissue. Having said that, we must also remember that the pulpless tooth is surrounded by living tissues like bones and gums and therefore, at times, an infection can recur in a tooth after being treated by root canal therapy. Although not very common, it can happen when:

  • There is a new decay around the filling of the root canal-treated tooth, the bacteria may enter into the root canal through the filling and begin to infect the bone tissue surrounding the tip of the root.
  • The bone tissue was already infected before the root canal treatment but was left undetected.
  •  Sometimes, an old root canal treated tooth which was normal can also develop infections

2. What are the common signs and symptoms of infection after a root canal?

Root canal infections can spread quickly all over your mouth therefore, it is important to detect and get them treated right away. Common symptoms include:

  • Pain in root canal treated tooth: Mild pain after the root canal procedure is normal, but if it is intense on biting or applying even slight pressure, or if the intensity of pain is the same or increases even after a week, it may indicate infection.
  • Swelling: If the gums surrounding your root canal-treated tooth appear swollen and tender, there may be an infection.
  • Discharge: If there occurs a pus discharge that may be colorless, white, or greenish, then the infection may be the cause.
  • Bad breath: A bad breath or an unpleasant taste in the mouth, even after a few days of the root canal treatment may indicate its infection.
  • Fever: Infection often results in an increase in body temperature.

Sometimes severe symptoms like difficulty in breathing or swallowing may occur for which one should immediately see a dentist.

3. Main causes of root canal infections.

Root canal infections may be caused due to:

  • The shape of the tooth: Sometimes the root canal shape can be complicated with narrow or curved canals, due to which the infected areas may go undetected during the procedure.
  • Accessory Canals: Some extra canals of your tooth may house bacteria and cause reinfection in the treated tooth.
  • Delayed capping of tooth: If permanent filling or the placement of a crown after the root canal is delayed or a crack or break in the filling may allow the bacteria to enter the canal and infect it.
  •  Cavities: A new cavity may develop just after the treatment resulting in reinfection.

4. How are root canal infections treated?

Root canal infections treatment can be done by:

1. A root canal retreatment, which is the same as your prior treatment. Your dentist may:

  • Take an X-ray to see the infected area around the root canal.
  •  Numb the area around the tooth by local anesthesia.
  •  Protect your gums and mouth with a protective rubber dam around the affected tooth.
  • Drill through the filling, enamel, and dentin to enter inside the root canal, via a dental drill.
  •  Remove the infected or decayed tissue and the old filling material and thoroughly clean the root canal.
  •  Dry the canal and fill a new filler material in the space created.
  •  Place a temporary filling onto the tooth to protect it, which shall be replaced by a permanent filling after 5-6 days.
  • The tooth may be prepared for the placement of a crown to strengthen it and prevent future infections.

2. Root canal surgery: It is done if the infection has spread beyond the root tip in the jaw bone.

3. Tooth extraction: If there occurs a tooth fracture or a split at the center of the tooth, then tooth removal is the only option.

There are a few tips that you may follow to prevent root canal infections further:

  • Maintain good oral hygiene: By brushing and flossing in a proper way at least twice a day.
  • Rinse your mouth with a gentle antiseptic mouthwash: This is important for at least the first few days after the root canal treatment to prevent the invading bacteria.
  • Use pain medications as indicated: Follow your dentist’s advice for medications to be taken to reduce pain and inflammation.
  • Do not delay permanent restoration and crowns: Follow up with your dentist at the earliest for your final filling and crowns.
  • Get your teeth professionally cleaned twice a year: This will help to keep your mouth and teeth healthy and also aid in the early detection of infection.

Seek immediate dentist’s help if you see signs of infection like pain, redness, swelling or discharge even if they are mild.

5. FAQ’s
