There is a growing number of people who have some type of Temporomandibular Disorder (TMD), being called a set of disorders that include the muscles, the temporomandibular joint and other regions of the oroface. The main signs and symptoms of TMD are pain, tenderness to palpation and joint crackles. In view of this, Botulinum Toxin emerged as one of the ways to alleviate the pain caused by TMD, as it works by reducing muscle activity. The aim of this review was to report the pharmacological use of botulinum toxin in the therapy of temporomandibular disorders. The study was carried out through a literature review from February 2019 to November 2019, in which articles in Portuguese, Spanish and English were searched. They were searched in databases such as LILACS, GOOGLE ACADEMIC and PUBMED, with articles from 2010 to 2019. It was noted that botulinum toxin is an important ally in reducing pain and in the general treatment of temporomandibular disorders, but in agreement with the current literature further studies are needed.
