Tooth whitening is a procedure for lightening the teeth in order to improve their appearance.

The causes of discoloration of the teeth:
Whether the teeth are abnormally brown or grey, or whether there has been a progressive alteration of their colour (colorants from food, drinks and cigarettes end up by penetrating the superficial layers of the enamel), there is now a solution that is both rapid and stable.

Early techniques were of doubtful efficacy, restrictive, less durable and could lead to sensitivity; now, the results are almost immediate and without side effects.

There are all sorts of methods on the market that are supposed to whiten the teeth (dentifrices, gums, adhesive tapes, kits sold by correspondence) but only one technique uses effective agents at a sufficient concentration to offer satisfaction.

Whitening must be performed in the dentist’s chair by a health professional and follow strict indications.

Among the contraindications:
Tooth whitening treatment is advised against in the following cases:

• Irregular coloration (from taking medicines, fluorosis, marks from mineralisation of the enamel)
• Pregnant women
• Children under 12 years
• Hypersensitivity of the teeth
