TMD Prevalence

The prevalence of signs and symptoms of TMD in the general population varies according to the different studies examined. Guidelines of the American Academy of Orofacial Pain estimate that 40% to 75% of the population displays at least one sign of the disease and 33% of the population reports at least 1 symptom. However, only 5% to 10% of adults with TMD symptoms require treatment and even fewer develop chronic or debilitating symptoms. The disorder is 1.5 to 2 times more prevalent in women than in men. Pain tends to occur after puberty, with the highest prevalence occurring in women aged 20 to 40 years.
