Tooth whitening can be done in the office or at home, although it is not possible to buy the same treatments for personal use. However, some dentists warn about the possible damage to dental pieces if they are used in high concentration without the prescription or follow-up of a dentist.
The whitening of the teeth allows to eliminate most of the stains produced by extrinsic causes such as tea, coffee and other infusions, cigarettes and red wine, among other substances and foods. However, not all dental stains or obscurations are removable or can be improved through tooth whitening and may require other types of aesthetic dental treatments such as the use of porcelain veneers or crowns.1
Usually a whitening is performed in the office that lasts approximately one hour, with which the patient already sees significant changes and a complementary treatment is indicated in the home, with the respective indications of the dentist. This treatment at high concentrations can be repeated as a maintenance after six months to a year, depending on the severity of the spots or pigmentations that the patient presents. In general, although it depends on the condition of the denture of each patient, it is important and necessary to perform a professional dental cleaning (ultrasound + professional brushing) before performing the teeth whitening and controlling any pathology present, such as caries, restorations defective.
