The search for increasingly whiter teeth urge the interest of pacientes in the dental whitening process. In this context, the brighteners toothpaste, which can be found in pharmacies and supermarkets, have been developed to complete the cleaning efficiency and allow dental whitening. These products can be indiscriminately used, without a permit, professional supervision or a dental prescription. Besides whitening substances, toothpaste has abrasive agents on its composition which can also cause whiter teeth. The abrasiveness degree depends on factors such as hardness of abrasive agents, the particle size and shape and the pH of the toothpaste. The abrasives that can be found in formulations are: hydrous silica, calcium carbonate, di-calcium dihydrate phosphate, calcium pyrophosphate, alumina, perlita or sodium bicarbonate. Daily brushing will change the dental enamel surface removing biofilm and superficial stain. Toothpaste containing oxidants or enzymes chemically change the pigments adhered to the teeth. Some brighteners toothpaste has in its composition charcoal and blue covarina, which abrasiveness in the dental enamel removes superficial stain and bacterial plates causing a false dental whitening impresion. This present study aims to verify through recent literature the efficacy of brighteners toothpaste in the process of whitening teeth and its possible adverse effects. In view of the results obtained, we conclude that more research is needed to warn about the side effects of these products in the long term.
