Bleaching — techniques for whitening teeth
Bleaching makes a smile brilliantly white again.
Discolouration can have many causes: tobacco, medicines and foods such as coffee, tea or red wine. Natural ageing also darkens the colour of the teeth.
Bleaching, a gentle method of lightening the teeth, makes a smile brilliantly white again. A peroxide gel is applied that sets off an oxidation process whose oxygen reaction alters the colour-bearing molecules in the tooth. Bleaching is suitable for treating individual teeth or a whole arch. If the teeth darken again after a time, the procedure can be repeated.
Bleaching should only ever be carried out under professional supervision. It can be done either at home or at the dental practice.
