Dental whitening is a procedure in which internal tooth pigments are removed using hydrogen peroxide or carbamide peroxide in gel form.
There are three types of bleaching:
– The one that takes place at home. In this method, the dentist makes transparent narthexes personalized to the teeth of each individual. He then places the jelly that the dentist has given him into the lozenges and then places them in his mouth. Depending on the formulation, you can wear them from one to a few hours every day until you achieve the desired result.
– The one done in the doctor’s office. In this method, the dentist places the gel with or without narthexes on the teeth of the person concerned and often the activation of the gel with a photopolymerization lamp is required. The desired result is usually achieved in 1-2 hours.
– Internal whitening performed in the office on endodontically treated teeth. In this case, the active substance is placed inside the tooth in order to act more deeply. Additional appointments are needed after certain days to replace the active substance until the desired result is achieved.
It should be noted that whitening on living teeth may sometimes create problems of dental sensitivity which can be treated most of the time.
However, a careful examination of the teeth should be done before treatment begins.
