People who have otherwise healthy teeth and gums can clench so often and so hard that over time their teeth become sensitive. They experience jaw pain, tense muscles and headaches along with excessive wear on their teeth. Forceful biting when not eating may cause the jaw to move out of proper balance.

Bruxism is triggered by people with certain types of personalities. They may have a nervous tension and a hard time handling stress. Anger, pain and frustration can cause people to start showing the beginning signs of bruxism without them even knowing it. People who are aggressive, competitive and hurried also may be at a greater risk for bruxism.
