1. What is teeth whitening?
Teeth whitening is used to lighten the natural colour of the teeth. Teeth whitening does not cause any permanent damage to the enamel or any other dental structures.
2. What are the factors that can change the colour of your teeth?
The teeth may get discoloured as you get old, by smoking, presence of tartar or can also be stained by food and beverages such as tea, blackcurrant, coffee, and red wine. Other factors include the use of antibiotics or small cracks in the teeth, which picks up the stain.
3. Which method is used for teeth whitening?
Bleaching is the widely used method for teeth whitening. The active component in the teeth whitening product is generally hydrogen peroxide or carbamide peroxide. This active component is broken down, and then the oxygen which is produced gets into the enamel on the teeth to make it look lighter in colour.
4. How long will my teeth stay white with this procedure?
Though the duration of effects of whitening can depend on a person, it is typically expected to last up to three years. The results will not stay for long if you drink red wine or coffee, and smoke as it can cause staining.
5. What are the side-effects of teeth whitening?
Some of the side-effects of teeth whitening include the teeth becoming sensitive to cold during or after treatment, pain or white patches in the gums and sore throat. These symptoms are usually transient, and it disappears within a few days after the treatment. Consult your doctor if any of these side-effects continue to persist.
