For several years, the ADA Standards Committee on Dental Products has been developing a new set of requirements for teeth whitening products. Now, recently approved by the American National Standards Institute in January, the guidelines are intended to verify the safety of common bleaching products used in dentistry.

According to the new guidelines, when externally bleaching natural teeth dental professionals must ensure that the enamel will not be eroded by the procedure, that soft tissue will remain undamaged, and that the concentration of active ingredients will remain at a safe level.

It is expected that the Council on Scientific Affairs will soon add the new standard, no. 136, to the ADA Seal of Acceptance Program Requirements. Manufacturers will then need to submit data on the safety and effectiveness of their teeth whitening products in order to display them with the familiar ADA seal of approval.
