Many inaccuracies are heard about the destruction of the tooth enamel from whitening. Whitening materials and techniques used in modern dentistry are safe and do not, under any circumstance, harm our teeth. What is considered as important is good oral hygiene, smoking avoidance and the no intake food with pigments (coffee, tea, red wine etc.) for a few days until the tooth enamel returns to its earlier state, the enamel which is only superficially affected by whitening. An essential precondition for the success of this dental work is the supervision of the whole procedure by our attending physician, whether it is done in the dental practice by the dentist, or at home with individual whitening nurses.
