Seek medical treatment if you experience chronic discomfort or soreness in your jaw, or if you are unable to fully open or close your jaw. Possible reasons and therapies for your condition might be discussed with your doctor, dentist, or a TMJ expert. Chronic tension or stress on the jaw muscles can lead to pain, stiffness, or other problems down the road. So the first step is to identify the cause of your tension or stress. This may include looking at possible contributing factors such as poor posture, grinding your teeth, or using chewing gum excessively. If you suffer from chronic tension or stress in your jaw, see a dentist or orthodontist to have any issues diagnosed and treated before they become serious problems. They may suggest exercises that can help prevent future tension or stress on the jaw muscles. Medical professionals can also offer advice on how to avoid putting additional strain on your jaw muscles. For example, you should try not to grind your teeth at night or use your computer in an uncomfortable position. In addition to being painful, also risk damaging your teeth if you don't take care of them. To protect your mouth and dental health, make sure to brush and floss daily, visit the dentist regularly for check-ups, and avoid smoking and drinking alcohol excessively.
