Your risk for temporomandibular disorder (TMD), a condition affecting your jaw bones, increases based on your age and gender. TMD is more common among women between ages 30 and 50. If you have a jaw injury or deformity where your jaw doesn't work properly or your teeth don't align properly, you are more likely to develop TMD. It also occurs more often in people with rheumatoid arthritis, fibromyalgia, chronic fatigue syndrome, or sleep disorders. You may also be at greater risk of TMD if you grind your teeth.
Risk factors for temporomandibular disorders (TMDs) include:
- Stress and anxiety, which can cause facial and jaw muscle tension.
- Repetitive habits, such as grinding your teeth (bruxism), clenching your teeth, excessive gum chewing, eating hard or chewy foods and nail biting.
- Habits that can cause muscle tension, such as sleeping on one side of your face or with your mouth open, opening your mouth wide when yawning or singing or holding your head up by cradling your jaw in your hand.
- Injury to the jaw or head. TMDs can result from a direct blow to the jaw, chin or head; whiplash to the head or neck; overstretching the jaw during dental work or surgery; or other injuries that may lead to joint damage or muscle tension.
- Age and gender. TMDs are more common in younger adults (ages 20 to 50) and in women.

Honor Society of Nursing (STTI) answeredThere are a variety of causes as well as risk factors for TMD. Women between the ages of 30 and 50 have higher incidences of TMD. Being under stress is a risk factor, as it may lead to jaw clenching and teeth grinding. Physical problems, like poorly aligned teeth, arthritis of the jaw, a dislocated jaw, or an inflamed temporomandibular joint will increase the risk of developing TMD. Dentures that fit poorly also increase the risk.
