Home bleachingSince
the Cosmetics Ordinance was amended in 2012, toothpastes for home use may only contain hydrogen peroxide up to a maximum concentration of 0.1%. Its bleaching effect is therefore limited to insignificant effects. What remains is a certain acidic effect and, with regular use, a roughening of the tooth surface (increased build-up of colour deposits).
bleaching agents from the trade are also low in concentration and therefore limited in their effect. Depending on the application, e.g. in the form of strips or sticks, unsightly stains may also appear on the teeth.
Sustainable bleaching results can only be achieved by a dentist. The dentist begins the bleaching therapy with a professional tooth cleaning and the treatment of carious lesions or leaking fillings, etc.
Only the dentist can assess findings such as exposed tooth necks and thin gums and then select the correct (responsible) bleaching technique.
In the event of side effects such as sensitivity or gum inflammation, the bleaching therapy is (temporarily) suspended.
Expert tip
Repeated bleaching in particular can lead to damage and pore formation on the tooth surface or roughen it. Colouring foods and stimulants such as coffee, tea or nicotine stains often adhere to the tooth surface.
