The causes of tooth discoloration are many, such as: various medications, tooth trauma, tooth nerve removal. Also foods that have dyes in the composition such as coke, coffee, affect the color of teeth.

How does the bleaching method work?

The substances used for bleaching are: Carbamide Peroxide and Hydrogen Peroxide (hydrogen peroxide). These two substances have the ability to pass freely through the layers of the tooth (enamel, dentin) and spread throughout the parts of the tooth. These Peroxides (Carbamide and Hydrogen peroxide) are broken down into oxygen radicals, which enter between the enamel prisms (the outer layer of the tooth), dispersing (destroying) the colored molecules that affect the color of the tooth.

Whitening does not affect the structure of the tooth, only that the inner color of the tooth becomes lighter (whiter).
