Grinding, clenching, and gritting your teeth are common reactions to stress — but their results can be quite complex. Here are some questions and answers that will fill you in on what you may not know about this widespread problem.
My dentist said I was bruxing. What does that mean?
Bruxing means that your teeth are grinding upon each other. Many people carry out this habit subconsciously and are not even aware that they are doing it.
Is bruxing or gritting harmful?
Such habits are called “parafunctional” (from para, meaning outside, and function, meaning purpose). This is because these stress habits exert much larger biting forces — as much as ten times more — than in normal biting and chewing activities. This excess pressure can cause damage to jaw joints and muscles, resulting in muscle spasm and pain; and to the teeth, resulting in wear, fractures or looseness. They can also cause headaches, earaches, and even neck and backaches because of the pressures on various structures in the face and mouth.
What is the usual treatment for problems arising from these stress habits?
The first thing we want to do is relieve your pain and discomfort. Second, we want to stop future damage. Application of heat or cold is helpful, and mild anti-inflammatory and muscle relaxant drugs are prescribed for pain and muscle spasm. To prevent future occurrences, we may treat you with biofeedback or refer you to someone who can offer psychotherapy.
What is a night guard and how can it help?
A night guard is an unobtrusive thin plastic appliance that is made to fit over the biting surfaces of your upper teeth. These guards are so unobtrusive that they can even be worn during the day if your stress level is so high that you grind your teeth during the day. The guard is adjusted to leave the lower teeth free to move against the surface of the guard, but they cannot bite into the upper teeth. This prevents wear on the teeth and lets the jaw muscles relax, preventing the pain of muscle spasm.
