The bleaching agents used in dentistry for tooth whitening cause changes that can lead to dentin sensitivity and pulp changes. This paper discusses the use of violet LED in tooth whitening as an alternative to tooth sensitivity. Currently, there is a need for further studies regarding the effectiveness and adverse effects of this technology, which proves to be an effective alternative to reducing the use or even replacing whitening gels that cause greater sensitivity after tooth whitening. This study is a literature review, with an exploratory qualitative approach through narrative review. Articles published between 2013 and 2023 in the main databases (PUBMED, MEDLINE, LILACS, SCIELO and BIREME) were selected through the combination of Boolean operators (and/and, or/ou, not/and not/ and not), without language restriction, using the descriptors “Tooth whitening”, “violet LED”, “dental sensitivity” and “Pulp dental”. Most studies point out that when there is greater infiltration of bleaching agents in the pulp chamber, it is related to the increase in gel concentration and/or time of exposure to the product, the number of sessions and pH of the product. The present work demonstrated that the use of violet LED in association or not with whitening gels can be an alternative, but that further investigations are still necessary on the real efficiency of this technology. Despite this, this study observed that the use of violet LED is a good option for tooth whitening and tooth sensitivity caused by bleaching using bleaching gels, given the shorter exposure time of the tooth to bleaching substances.
