A risk factor is something that increases your likelihood of getting a disease or condition.
It is possible to develop TMD with or without the risk factors listed below. However, the more risk factors you have, the greater your likelihood of developing TMD . If you have a number of risk factors, ask your doctor what you can do to reduce your risk.
Risk factors for TMD include:
People who have a lot of stress in their lives may have an increased risk of TMD. Some of the stress-related habits that may increase your risk of TMD include:
- Habitually clenching and unclenching your jaw
- Grinding your teeth during the day and/or at night in your sleep
- Constantly or very regularly chewing things, such as gum or ice, for long periods of time
The following medical conditions may increase your risk of TMD :
Most people report TMD symptoms between the ages of 30 and 50.
Women are three times as likely as men to develop TMD.
Poorly fitted dentures are thought to be a risk factor for TMD.
Other Risk Factors
There is some evidence that women taking ]]>hormone replacement therapy]]> are more likely to develop symptoms of TMD.
