Tooth bleaching is a cosmetic and conservative treatment, that allows to reduce the effects of dental chromogens (e.g. caffeine, theine, carotene, etc.), a kind of organic compounds responsible for pigmentation of teeth, in order to get back a brighter colour.

Such a process is possible thanks to the chemical properties of specific substances called peroxides, that can oxidize the chemical bonds of the substances causing tooth coloration. Dental bleaching can involve both vital and necrotic teeth and can be carried on both in the dental office and at home, by means of customized templates to be worn by patients during night.

Bleaching procedures have not to be confused with tooth cleaning, that indicates the removal of supra- and sub-gingival plaque and tartar.
