Patients are very frequently dissatisfied with the color of their teeth, which can be inadequate for many reasons: genetics, taking antibiotics, vitamins and minerals; consuming food and drinks that stain the teeth; smoking, aging, etc. In such cases, bleaching is recommended.
There are two methods of bleaching: at-home bleaching using a tray and in-office bleaching.
In both cases, bleaching is preceded by cleaning and sandblasting the teeth.
At-home bleaching is performed with individual trays containing a 10 or 16 percent solution of carbamide peroxide. A tray is filled with the bleaching agent and is worn at night, first on one jaw and then on the other. The duration of the treatment depends on the degree of tooth discoloration and the expected color. It is usually between 15 and 20 days for each jaw.
In-office bleaching is performed with a 35 percent solution of carbamide peroxide. The treatment requires several visits. The final result is apparent after several weeks, when the color becomes permanent.
Tooth sensitivity is the most common side effect of bleaching. Therefore, a fluoride varnish is recommended during treatment.
