Tooth Whitening / Dental Bleaching

What is Tooth Bleaching?

The colour of our teeth is determined by the enamel which is the outer layer, and inner layer of hard tissue known as dentine. The shade and thickness of these two dental hard tissues will primarily determine the colour of our teeth. A variety of external and internal factors can modify this natural colour of teeth resulting in staining or darker looking teeth. The extrinsic causes of tooth discolouration are generally due to beverages such as tea or coffee or due to tobacco. On the other hand, birth defects due to some genetic disorders or trauma to teeth may cause discolouration of your teeth from the inside.

Most whiteners use peroxide compounds to whiten teeth. The peroxide compounds break down into hydroxyl free radicals, penetrate into the enamel and dentine where they react with the stain and thus lighten the tooth by a process of oxidation.

The market today is flooded with products and options for tooth whitening from which a patient can choose. The treatment options include professional bleaching that is done by the dentist in his/her clinic or supervised by the dentist or home bleaching where the procedure may be performed at home using products that are available over the counter.

The advantage of all these procedures is that they are relatively easy to use with noticeable results achievable in a few sittings.

As is the case with any treatment, tooth whitening is also associated with a variety of side effects such as sensitivity, pain and inflammation of gums. It is important that the cause of tooth discolouration and the probable result be determined before any treatment option is chosen.

Hi imaya, using lemon cannot be supported as it can cause erosion of the Dental enamel as it contains citric acid, which even can cause gastritis in person who are having acidity.
