It is usually photoactivatable hydrogen peroxide, which means that it increases its whitening action when exposed to a source of cold light Denta Seal Review. In addition, this type of products are not abrasive and do not maintain the integrity of the tooth enamel.

The process can consist of three cycles of 15 minutes of photoactivation, replacing in each of them the bleaching gel.

Dental whitening by photoactivation can be complemented with a home treatment, for which the dentist himself will provide the patient with a splint and hydrogen peroxide or Denta Seal Review and will indicate how it should be carried out, for a period of four and a half.
