Clenching, or grinding of your teeth (also known as bruxing) are common habits. Biting forces are normally small, gentle, fleeting and very frequent throughout the day. In fact, it's the normal stimulus necessary to keep your teeth and jawbone healthy. When you clench or grind your teeth you apply forces up to ten times normal (in the 200 lb range). And it's not just the force, it's the duration and frequency with which they're applied. High forces lasting for seconds or minutes, frequently exerted, can affect some or all of the masticatory system. This includes the teeth, jaws, jaw joints and muscles, causing aching jaws, headaches, earaches, neck and even backaches; and the teeth themselves causing excessive wear, fractures, or even loose teeth.
Why does grinding occur? Habitual grinding is most frequently a reaction to stress. Sometimes abnormalities in your bite or malocclusion (“mal” – bad; “occlusion” – bite) can trigger clenching or grinding. It is normal for children to sometimes grind their teeth when new teeth are coming in, but it may be indications of stress too. You may be grinding your teeth subconsciously in your sleep, but it may be so loud as to awaken your sleeping partner. Or our office may be the first to suspect it during a dental exam because of the apparent signs of change to muscles, joints and teeth especially abnormal tooth wear.
What can be done about teeth grinding or bruxing? If you are symptomatic, having pain, muscle, joint or tooth soreness, the first step is to get you comfortable. Generally, a mild non-steroidal anti-inflammatory medication (aspirin, ibuprofen) and muscle relaxants will help in addition to moist heat and mild jaw exercises. Stress management is also helpful. To prevent further damage, we may recommend a bite guard made of wear-resistant plastic that fits over the biting surfaces of your upper teeth. These customized unobtrusive appliances when properly fitted and adjusted stop clenching and grinding activity, or at least the damage they can do. A bite guard can be worn day or night especially during stressful periods.
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.
