"Dentists and patients alike should be aware of the potential health effects from overuse of tobacco, alcohol and caffeine," said Michael Glick, D.M.D., editor of JADA. "This study is a great contribution to the dental community's growing knowledge on this topic."

Researchers conducted a systematic review of the literature and found seven studies that met their criteria. The studies ranged in size from 51 to more than 10,000 people who ranged from 18 to 55 years of age. According to the review, smoking tobacco can more than double the odds of teeth grinding, drinking alcohol nearly doubles the odds, and heavy caffeine drinking (more than 760 milligrams a day) increases odds by one and a half. 

In addition to drugs such as alcohol and tobacco, teeth grinding has also been linked to stress, sleep disorders, abnormal bite and other factors. Symptoms of teeth grinding include dull headaches, jaw soreness, muscle pain, teeth that are painful or loose and fractured teeth.

Patients who experience symptoms of teeth grinding should talk to their dentist about potential causes and solutions. For additional information on teeth grinding, visit
