It is an aesthetic dental treatment that reduces the original color of the teeth by several tones, leaving the teeth whiter and brighter. Teeth whitening can be done in the office or at home, although the same treatments cannot be purchased. However, some dentists warn of possible damage to teeth if used in high concentrations without a prescription or monitoring by a dentist.

Teeth whitening eliminates most stains caused by extrinsic causes such as tea, coffee and other herbal teas, cigarettes and red wine, among other substances and foods. However, not all dental stains or darkening are removable or can be improved through teeth whitening. They may require different types of cosmetic dental treatments, such as porcelain veneers or crowns.

Whitening has no effect on any restorations, including: amalgams, restorations made with halogen light (resins or white fillings), inlays and crowns, or bridges.

To replace these restorations, it is necessary to wait approximately 15 days for the color obtained with whitening to stabilize.
