ACHACHAO ALMERCO, Kelly  and  TAY CHU JON, Lidia Yileng. Therapies to decrease tooth whitening sensitivity. Rev. Estomatol. Herediana [online]. 2019, vol.29, n.4, pp.297-305. ISSN 1019-4355.  http://dx.doi.org/10.20453/reh.v29i4.3639.

The most common side effect in tooth bleaching is tooth sensitivity because of the pulp reaction to free radicals produced by the hydrogen peroxide used in bleaching products. Different therapies have been used before, during and after to reduce tooth sensitivity, agents that block nerve repolarization such as potassium nitrate and agents that block dentinal tubules: amorphous calcium phosphate, calcium sodium phosilicate, calcium gluconate, hydroxyapatite, GLUMA and fluor; alternative therapies such as the use of anti-inflammatory, antioxidants and laser application which have also been mentioned in the literature. The aim of this review is to show the scientific evidence on the different methods to decrease the sensitivity on tooth bleaching.

Keywords : tooth bleaching; dentin desensitizing agents; therapeutics.
