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.”
After ruling out other possibilities for your constant jaw joint pain, your doctor has diagnosed you with a temporomandibular disorder (TMD). Now that you know what you have, what can you do about it?
Unfortunately, it's not always an easy answer. Ideas about treatment are almost as numerous as theories on the causes of TMD. By and large, though, we can classify treatment into two broad categories: conservative and aggressive.
The conservative approach is the result of many years of experimentation and application; it's also much less invasive than aggressive treatments. For most patients, though, these treatments can offer significant relief from pain and dysfunction.
Conservative treatments are based primarily on the philosophy that the temporomandibular joint is like any other joint, and should be treated that way. Treatments include thermal therapies like ice or heat packs applied to the jaw, physical therapy (gentle stretching, jaw exercise, and massage) and pain and muscle relaxant medication. In cases where teeth grinding may be a contributing factor, we might recommend a bite guard worn in the mouth to reduce biting pressure.
On the other end of the spectrum are treatments like altering the bite or the position of the jaw. The purpose of bite alteration is to change the dynamic when the jaws are in contact during chewing or clenching, and reduce pressure on the joints. This is often done by reshaping the teeth's biting surfaces, moving the teeth with orthodontics or performing crown and bridgework. Another possibility, actually modifying the lower jaw location, requires surgery. All of these aggressive treatments are done in order of less to more invasiveness.
These more aggressive treatments, especially jaw surgery, are irreversible. Furthermore, studies on results have not been encouraging — there's no guarantee you'll receive relief from your symptoms. You should consider the aggressive approach only as a last resort, after you've tried more conservative measures. Even then, you should get a second opinion before undergoing more invasive procedures.
Hopefully, you'll see relief from therapies that have made a significant difference for most TMD sufferers. And that's our goal: to reduce your pain and dysfunction and help you regain your quality of life.
