Ever since childhood, when her career as a model and actress took off, Brooke Shields has enjoyed worldwide recognition — through advertisements for designer jeans, appearances on The Muppet Show, and starring roles in big-screen films. But not long ago, that familiar face was spotted in an unusual place: wearing a nasal anesthesia mask at the dentist's office. In fact, Shields posted the photo to her own Instagram account, with the caption “More dental surgery! I grind my teeth!” And judging by the number of comments the post received, she's far from alone.
In fact, researchers estimate that around one in ten adults have dental issues that stem from teeth grinding, which is also called bruxism. (Many children also grind their teeth, but it rarely causes serious problems, and is often outgrown.) About half of the people who are teeth grinders report problems like persistent headaches, jaw tenderness and sore teeth. Bruxism may also result in excessive tooth wear, and may damage dental work like crowns and bridges; in severe cases, loosened or fractured teeth have been reported.
Researchers have been studying teeth grinding for many years; their findings seem to indicate that it has no single cause. However, there are a number of factors that play a significant role in this condition. One is the anatomy of the jaw itself, and the effect of worn or misaligned teeth on the bite. Another factor relates to changes in brain activity that occur during the sleep cycle. In fact, nocturnal (nighttime) bruxism is now classified as a sleep-related movement disorder. Still other factors, such as the use of tobacco, alcohol and drugs, and a high level of stress or anxiety, can make an individual more likely to experience bruxism.
What can be done for people whose teeth grinding is causing problems? Since this condition may have many causes, a number of different treatments are available. Successful management of bruxism often begins by striving to eliminate the factors that may cause problems — for example, making lifestyle changes to improve your health, creating a soothing nighttime environment, and trying stress-reduction techniques; these may include anything from warm baths and soft music at bedtime, to meditation and mindfulness exercises.
Several dental treatments are also available, including a custom-made occlusal guard (night guard) that can keep your teeth from being damaged by grinding. In some cases, a bite adjustment may also be recommended: In this procedure, a small amount of enamel is removed from a tooth to change the way it contacts the opposite tooth, thereby lessening the biting force on it. More invasive techniques (such as surgery) are rarely needed.
A little tooth grinding once in a while can be a normal response to stress; in fact, becoming aware of the condition is often the first step to controlling it. But if you begin to notice issues that could stem from bruxism — or if the loud grinding sounds cause problems for your sleeping partner — it may be time to contact us or schedule an appointment. You can read more about bruxism in the Dear Doctor magazine article “Stress and Tooth Habits.”
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.
