Abstract
Objective: Check the consequences of agents that are present in bleaching products to dental tissues, and the proper technique for their use, aiming to alleviate the sensitivity that so many patients demonstrate to have right after their application. Bibliographic review: There are two techniques that can be used by the Dental Surgeon (CD) for the tooth whitening process, namely: what is done in the dental office and the homemade one, frequently supervised by professionals. The treatment carried out in the dental office uses hydrogen peroxide or carbamide in a higher concentration, when compared to that carried out at home, the procedures performed in the patient's office present desired results in less time since the concentration of these agents varies from 35 to 40%. In order to provide an adequate and individualized treatment, it is necessary to take a good anamnesis in the patient, trying to find out if there is a history of sensitivity, if they are smokers, pregnant women, people with pre-cancerous lesions and allergies. Final considerations: The professional must be careful in using the correct technique. Furthermore, with the great search for whiter teeth, new research on this topic is emerging, which is why it is important for professionals to always update themselves in order to provide the best comfort for their patients.
