It can be alarming to be awakened in the middle of the night by a screeching, gritting sound coming from your child’s bedroom. No, it’s not a scene from a horror movie: it’s your child grinding their teeth as they sleep — a behavior so prevalent in children under eleven it’s considered normal.
That doesn’t mean, however, you should completely ignore it. While it isn’t harmful for most children, a few can encounter tooth wear, pain or trouble sleeping that calls for some form of intervention.
The causes for tooth grinding and similar habits known collectively as bruxism aren’t thoroughly understood, but in children it’s believed linked to the immaturity of the neuromuscular system that controls chewing. Some point to shifts from one stage of sleep to another — more than 80% of grinding episodes occur in lighter stages of sleep and only 5% to 10% during the deeper Rapid-Eye-Movement (REM) stage. It also seems prevalent in children who snore or have other symptoms of sleep apnea.
One primary concern is how the behavior can affect teeth, particularly through abnormal wear. The teeth, of course, make hundreds of contacts with each other every day during eating, speaking or jaw movement. If, however, the forces generated during these contacts chronically exceed normal parameters, as with bruxism, it can cause accelerated tooth wear. This can result in a higher susceptibility to tooth decay and appearance changes later in life.
If your child is exhibiting problems associated with teeth grinding, there are ways to address it. We may recommend a thin, plastic mouthguard they wear while sleeping that prevents the teeth from making solid contact with each other. We may also refer you to an ear, nose and throat specialist if we suspect signs of sleep apnea. And, children under severe psychological stress, which can also trigger teeth grinding, could benefit from behavioral therapy.
The good news is most grinding habits fade as children enter their teens. In the meantime, keep a watchful eye and see us if you notice any indications this common habit is affecting their health and well-being.

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.”
Modern life can be demanding. The body helps us rise to the occasion through responses we collectively call stress.
But while stress can be a good thing, it can also overwhelm us and manifest in some harmful way: bouts of back pain, stomach ulcers or even acne. It could also trigger tooth grinding, often occurring as we sleep. And like other stress relievers, tooth grinding can be detrimental to your health long term.
Teeth-on-teeth contact occurs normally when we eat or speak, or simply as our jaws contact each other with glancing touches hundreds if not thousands of times a day. Such normal contact is beneficial because it stimulates healthy bone growth in the jaw. But if the forces created exceed the normal range as with tooth grinding (up to ten times), it can cause a bevy of problems to the teeth and jaws.
While excessive jaw motion during teeth grinding can cause inflammation and painful spasms in the muscles, the greater danger is to the teeth, which could even fracture from the high amount of force. The more common occurrence, though, is an increased rate of enamel erosion, which causes the tooth to lose vital structure and eventually appear shorter in appearance.
Fortunately, there are ways to reduce teeth grinding or its severity. The first order of business is to treat its effects by reducing its symptoms and ongoing damage. We can recommend some behavior modification techniques to alter the frequency of the habit or a night guard to protect the teeth from the intensity of the habit if you’re unable to change the behavior.
A custom-fitted night or occlusal guard, a retainer-like dental appliance made of smooth acrylic plastic is designed so that the lower teeth glide over the guard surface when grinding and can’t make solid contact with the upper teeth. This reduces the generated force and helps protect the teeth.
In the long term, though, you should address the root cause — how you’re handling daily stress. Treatment by a psychotherapist or counselor, for example, could help you develop ways to channel stress in more productive ways.
However your treatment strategy develops, it’s important to address stress and teeth grinding as soon as possible. Controlling it will have long-term benefits for your teeth and smile.

Teeth grinding and other biting habits are more than a nuisance — they can generate twenty to thirty times the forces of normal biting. Over the long term, this can cause significant damage to teeth and supporting gums and bone.
This particular kind of damage is known as occlusal trauma (meaning injury from the bite). In its primary form, the habit itself over time can injure and inflame the jaw joints leading to soreness, swelling and dysfunction. The teeth themselves can wear down at a much faster rate than what normally occurs with aging. And although less common but even more serious, the periodontal ligaments holding teeth in place to the bone can stretch and weaken, causing the teeth to become loose and increasing the potential for tooth loss.
There are a number of techniques and approaches for treating excessive biting habits, but they all have a common aim — to reduce the amount of force generated by the habit and the associated problems that result. A custom occlusal guard, often worn while sleeping, helps lessen the force by keeping the teeth from making solid contact with each other. Tissue soreness and swelling can be relieved with anti-inflammatory drugs like aspirin or ibuprofen, muscle relaxants or physical therapy. In cases where stress is a main driver, behavioral therapy and counseling may also be helpful.
Biting forces are also an issue for patients with periodontal (gum) disease. In this case even biting forces within normal ranges can cause damage because the diseased gums and bone have already been weakened. If gum disease is a factor, the first priority is to treat the disease by removing built up plaque. Plaque is the thin film of bacteria and food remnant that’s both the cause and continuing growth of the infection, as well as tartar (calculus) from all tooth and gum surfaces.
A thorough dental exam will reveal whether a tooth grinding habit is playing a role in your teeth and gum problems or if it’s magnifying the damage of gum disease. In either case, there are appropriate steps to stop the damage before it leads to tooth loss.
