With a prevalence of approximately 10 percent and an incidence of approximately 3 percent per year, Temporomandibular Disorders (TMD) is a significant health condition that cannot be ignored. The prevalence of TMD in adult populations is between 10 and 15 percent, but only 5 percent of the population seeks treatment. The PICO structured summary approach was selected as a strategy for organizing clinical research issues related to evidence synthesis. This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 20202) criteria and protocols. A comprehensive search was conducted using EBSCOhost, PubMed, NCBI, Scopus, and Clinical Key. Based on the available literature, mental stress is considered a predisposing factor that causes bruxism. It is of high importance to relieve this excessive clenching effect to further preserve the morphological and physiological teeth, periodontium and temporomandibular joint functions. Therefore, updates and appraisals of the available evidence and literature are needed to sufficiently send information to healthcare providers. It is recommended to further educate the general population about bruxism, its causes and how to limit the risk factors associated with it through the national public health education programs.
