Any discomfort or pain when the teeth get in contact with hot, cold, sour or sweet, that means your teeth have become sensitive and need help. It happens even while performing activities such as brushing and flossing.

Sensitive teeth are due to wearing of tooth enamel that exposes the dentin layer. Exposure of dentin causes sensitivity as the nerves can directly feel the food causing this temporary effect.

It is observed that most of us experience tooth sensitivity at some or the other time. Excessive grinding, vigorous brushing or acid erosions are some of the causes of such sensitivity.

1. What is Teeth Sensitivity?

Dentin hypersensitivity or dental sensitivity are other names of tooth sensitivity. Certain studies suggest that around 10-30% of the population regularly have dentin hypersensitivity.
It can start at any time and can be seen in all age groups right from children to teenagers to aged adults. It is observed that tooth sensitivity is more commonly seen in women than men. Dental sensitivity can affect even a single tooth or set of teeth.

We can define dentin hypersensitivity as short, sharp pain arising from exposed dentine, typically in response to chemical, thermal or osmotic stimuli that cannot be explained. Here, hypersensitivity means that the dentine is exposed and the pulp is accessible to damage.
Generally, The enamel layer covers the crown of the tooth and the tooth is cushioned over the gums or gingiva. Sometimes, the gums move back or recede and part of the enamel layer at the meeting place of the tooth and the gum wears off easily. This is because the enamel layer in that region is very thin. This erosion of the enamel layer causes the inner dentine to get exposed.

The dentine has numerous microscopic tubules or channels that lead to the nerve centre or the pulp. The exposed dentine tubules pass the stimuli such as hot, sweet, sour or cold to the nerves. The nerves are sensitive to such stimuli causing sharp pain and discomfort. One can experience mild to severe pain even for several hours.
Dentin hypersensitivity is a warning signal for more serious dental problems. If the pulp and the dentine layer is exposed for a long duration and left untreated, the tooth can be vulnerable to further damage causing oral health problems such as gingivitis, periodontitis, tooth caries, etc.

2. What Causes Tooth Sensitivity?

It is clear that sensitivity is a result of exposure to dentine due to the erosion of enamel. Causes of sensitive teeth can be related to lifestyle and oral hygiene habits. These habits lead to wearing out of the upper enamel.  Some of the causes are mentioned below.

  • Using a hard toothbrush – Brushing hard, improper brushing or using a hard toothbrush can cause wearing of the protective enamel especially where the teeth meets the gums. The exposed dentine can further result in sensitivity.
  • Acid refluxes – When acids of the stomach get in touch with the teeth, an acidic oral environment is created within the mouth that can cause erosion of the enamel layer. The tooth’s enamel layer is sensitive to acids. Acidic foods and beverages also wear out the enamel leading to sensitivity.
  • Oral hygiene issues – When plaque stays on the teeth, it hardens to form tartar. People with oral hygiene problems can face tooth sensitivity. The tartar piles up around the gums and teeth. These pockets of tartar can either cause the gums to recede and cause gum problems or can damage the tooth immensely. In both cases, erosion of enamel can cause exposure to the pulp region.

  • Grinding of teeth – People with a habit of clenching and grinding the teeth together can have sensitivity. As constant grinding can wear out the enamel layer.
  • Tooth problems – Cracked teeth can make the tooth sensitive to extreme temperatures. People having issues such as broken teeth, chipped teeth, tooth decay can leave the dentine layer exposed causing tooth sensitivity.
  • Improper tooth fillings – Sometimes the temporary tooth filling during certain dental procedures can wear out. This wearing out exposes the pulp region to food causing sensitivity and pain.

Teeth whitening and sensitivity –Tooth cleaning procedures and teeth whitening treatmentsare also the reasons for sensitive teeth that can cause temporary effects.

Understanding Other Most Common Dental Problems

Maintaining good oral health is essential for overall well-being. Here are some of the most common dental problems that individuals often encounter:

Tooth Decay (Cavities) 

Tooth decay, or cavities, occurs when bacteria in the mouth produce acids that erode the enamel. This can lead to the formation of small holes in the teeth, causing pain and sensitivity.

Gum disease is an infection of the tissues supporting the teeth. It ranges from gingivitis (mild gum inflammation) to periodontitis (severe infection). Symptoms include swollen, red gums, bleeding, and bad breath.
