Bleaching of teeth is a procedure which is useful in  lightening  discolorations which have accumulated on the tooth surface over a period of time. This process causes the whitening  of  teeth with the help of a mild  bleaching solution. This method is ideal for stains caused by age or food. 
What causes staining of teeth?

The most common causes include aging, consumption of staining substances (coffee, tea, colas, tobacco, betel nut etc.), and old discolored fillings in the teeth. During tooth formation, consumption of the antibiotic tetracycline or excessive fluoride may also cause tooth discoloration.

How is bleaching done?

 Bleaching is performed by two separate methods.

1. One is the In-office bleaching and the other is a commercially available tray system. 
2. With the  in-office bleaching technique, a bleaching gel is applied over the teeth and a special light is used to activate the bleaching gel so as to begin  the whitening process. The facility for this method is available only in the dental clinic. 
3. In  tray bleaching system, trays are usually provided  along with the commercial teeth whitening pack. These trays are designed so as to cover the tooth surface when placed in to the mouth .The bleaching gel is carried to the tooth surface  with the help of these trays. The trays are usually  worn for a  few hours every day for a period of 7 to 10 days. Although slower, the results achieved are usually comparable to the in-office bleaching.
4. For the maximum whitening,  a combination of the two techniques is recommended.


Is the process safe?
YES. All clinical studies have shown that tooth whitening is a safe process when done under the supervision of a dentist. Reports that claim that the bleaching gel will destroy your teeth are not true. The bleaching process causes no long-term harmful effects to your teeth or gums.
