Bleaching is a procedure to whiten teeth and makes the appearance fresher, younger and more dynamic. A gel (Peroxide) is placed on the tooth substance and a special light is increasing the efficacy. The gel is bonding to the color molecules that are inside the tooth substance and transport them outside through little tooth channels (dentine tubules). Several procedures in one session are repeated and after every session the patient can check the result.
After the treatment the patient should avoid drinking black tea, coffee, cola, red wine for one week and should avoid to eat ketchup, curry dishes and paprika as well for one week. This helps to prolong the result. Depending on the eating and drinking behavior of the patient the duration of maintenance of a nice result might vary. Several bleachings during one year have no impact to the tooth substance as many times regarded as a common assumption.
