A dark colouration or stains on your teeth can be lightened in various ways, but always with the same product, hydrogen peroxide (hydrogen peroxide)
There are several techniques
- A personal cast that the patient will wear at home during the day (for about 1 hour) or at night (all night). The number of applications depends on the needs, but it oscillates between 10 and 30. After treatment it may be necessary to apply the cast periodically to maintain results.
- The use of a highly concentrated gel that the dentist applies directly to the teeth for 15 minutes. This technique can be implemented only in the dental office and requires 3-6 applications spread over 2 to 3 sessions.
These treatments are only applicable to healthy teeth. A maintenance session may be needed once or twice a year, depending on the person.
