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.”
“What can I do about my child's teeth grinding habit?”
It's a common question we get from many concerned parents. Their exasperation involves more than having to wake every night to the annoying sounds coming from their child's bedroom: they're also worried about any potential damage occurring to their teeth.
Teeth grinding and similar habits fall under the umbrella term “bruxism.” In basic terms, bruxism is the involuntary movement of the teeth and jaws not engaged in regular functions like chewing, speaking or swallowing. Bruxism is actually common among pre-adolescent children, considered by many healthcare professionals as normal behavior like thumb sucking.
It's not fully known why children grind their teeth, especially during sleep. Stress can play a part, but many believe it could also be related to immaturity on the part of the neuromuscular system that controls chewing. In some cases it could be linked to sudden arousals from sleep, particularly if the child is prone to airway obstruction causing sleep apnea. And there may be a link with certain medications, especially for hyperactivity disorders like attention deficit hyperactivity disorder (ADHD).
Most children eventually outgrow the habit. If it persists, though, it can contribute to teeth problems. Teeth can withstand a lot of biting force, but when chronically exposed to the higher than normal forces produced during teeth grinding they can begin to wear. Sodas, fruit juices, sports drinks or similar acidic beverages complicate matters because they increase mouth acid that can soften enamel. And besides dental issues, teeth grinding can also cause jaw problems, ear pain and headaches.
If symptoms begin to appear, we can take steps to reduce the effect of teeth grinding, such as a mouth guard worn at night to reduce biting forces and protect against wear. We can also look at curbing consumption of acidic foods and beverages, addressing possible airway obstructions, changing medications or counseling for psychological stress.
As with thumb sucking, there's no cause for immediate alarm if your children grind their teeth. But if it continues on into their later childhood years or begins to affect their health and well-being, we'll need to intervene to prevent further harm.
