WHAT IS TOOTH WHITENING / BLEACHING?
Teeth Whitening is the process of bleaching your teeth in order to make them appear whiter. It can be done at home or best by a dentist, and is a purely cosmetic procedure, In South Delhi Gk1 Orion Orthodontic & Dental Care Centre offers both in office as well as home bleach procedures.
WHAT ARE THE CAUSES OF YELLOW AND DISCOLOURED TEETH?
Some of the factors that cause teeth to look yellow and discolored are:
- Smoking with by-products of tar and nicotine, leaves unsightly brown stains.
- Beverages such as tea and coffee will have the same effect over time.
- Teeth can naturally be a darker shade than desired due to heredity.
- Wearing braces or other dental apparatuses for extended periods of time will discolor enamel.
WHAT ARE THE METHODS TO WHITEN TEETH?
Individuals have the option of using teeth whitening toothpastes, at-home bleaching methods or in-office bleaching methods.
- Whitening toothpastes remove stains from the surface of enamel by means of a mild abrasive; they do not change the color of the enamel. Whitening toothpastes contain a chemical that provides additional stain removal. Peroxide is one of the usual substances used. In over-the-counter formulas, peroxide is generally found at most to have a strength of 10%.
- Another option is the at-home method using bleaching gels and trays or mouth guards. A foam type tray is filled with the peroxide gel, placed over the upper or lower teeth, and worn for a specific amount of time; generally overnight or twice a day, for 1-2 weeks. This method also only removes stains. Enamel color is not changed. Occasionally soft gum tissue becomes irritated. These results are from using too much gel or from an improperly fitting tray. A custom fitted tray, obtained from a dental practitioner, will lessen this adverse effect
- In-office teeth whitening involve a similar method – the peroxide gel a dentist uses has a much stronger concentration of peroxide. This gel contains 16% or more of peroxide. This specially formulated gel actually bleaches the enamel from the inside out. A protective gel is first applied to gum tissue to protect against irritation. Then the bleaching agent is applied to the teeth. A special light is used to enhance the chemicals in the bleaching formula. The process takes 30 minutes to 1 hour. More than one visit may be needed to whiten lower and upper teeth. Dentists advise that in certain instances enamel color may not significantly change, if teeth are extremely darkened.
ARE THERE ANY SIDE EFFECTS DUE TO TEETH WHITENING?
A side effect of teeth whitening is the teeth’s sensitivity to air and exposure to extreme temperature changes, such as eating hot or cold foods. During the whitening process, enamel pores open, allowing these changes to penetrate and cause discomfort. Saliva contains minerals that aid in the healing process of closing pores by filling them, but this can be a timely process.
