| Summary: | The appreciation of aesthetics has become usual during dental treatment, with tooth whitening being one of the most sought procedures for the treatment of color changes and several authors consider that the white diet is important so that its aesthetic result is not compromised. However, other authors state that the ingestion of food and drinks with dyes does not interfere immediately and later in the result of the bleaching treatment. This article verifies, through literature review, if the white diet is really necessary during or after tooth whitening. A bibliographic search was performed in LILACS and PUBMED, and 16 articles were found that met the inclusion criteria. In vitro, in situ and in vivo studies exposed in this work report that there is no interference of pigments during bleaching on the result of the procedure. There is also a consensus that after the bleaching treatment, red wine interferes with color maintenance. Therefore, indicating the white diet is still a recommendation that is partially not based on scientific evidence, due to the lack of congruence in research results.
