Teeth whitening

Nowadays, the importance given to dental aesthetics is increasing day by day. Preservation of natural tooth structure by patients and dentists is just as important. Obtaining an aesthetic smile by preserving the natural tooth structure has made the teeth whitening process very important in dentistry.

Teeth whitening is one of the most protective methods of removing stains on the teeth.

The most commonly used material in teeth whitening is hydrogen peroxide. Hydrogen peroxide passes through the enamel and dentin and interacts with the chromogen molecules that cause tooth discoloration, and oxidizes these molecules and removes the dark coloring.

1.  What causes color change in teeth?

Factors such as food and beverages consumed in daily life (tea, coffee, cigarettes), some drugs used by the mother while in the mother's womb, some drugs used during infancy, fluoride level in drinking water, and inadequate oral care may cause discoloration in the teeth. This coloration of the teeth is divided into two:

External discoloration: It is the coloration seen as a result of external factors sticking to the outer surface of the tooth.

Internal discoloration: It is the coloration of the inner surface of the tooth that does not go away with advanced brushing or tooth cleaning.
