1. What is teeth whitening?
Teeth whitening is a procedure to make the colour of the teeth appear whiter. This process does not harm the enamel or any other tooth structures when performed by a professional dentist. It can be done either by removing the stains or by use of chemicals that can lighten the tooth colour.
2. What are the factors that can change the colour of your teeth?
The factors that can cause discolouration of teeth include:
presence of tartar
food and beverages that can lead to staining such as tea, blackcurrant, coffee, and red wine
little cracks in the teeth that can take up stains
3. Which method is used for teeth whitening?
Bleaching is one of the most frequently used methods for teeth whitening. Hydrogen peroxide or carbamide peroxide is the active ingredient in many teeth whitening products. These bleaching materials react with the compounds in the tooth stain and oxidise it to lighten the tooth colour.
4. How long will my teeth stay white with this procedure?
The effects of teeth whitening procedure are expected to last at least for three years, although this can vary from person to person. For example, drinking coffee or red wine and smoking can raise the chances of staining, and this can decrease the duration of the effect of the procedure.
