Brief Summary

Individuals with chronic temporomandibular disorder (TMD) pain are at increased risk for alcohol-related consequences compared to those without pain, and growing evidence suggests pain is a potent motivator for alcohol use in many individuals. However, few systematic examinations of modifiable and non-modifiable risk factors, including orofacial pain status, have been conducted. This project addresses this gap in knowledge by determining the effect of pain on drinking topography in heavy drinkers with and without chronic TMD pain in both the laboratory and daily life.
