Along with thumb sucking, childhood teeth grinding is one of the top concerns anxious parents bring to their dentists. It’s so prevalent, though, many providers consider it normal behavior—the sleep-disturbing sound it can generate is often the worst consequence for the habit.
But that doesn’t mean you should brush aside all concern, especially if the habit continues into late childhood. Long-term teeth grinding could eventually damage the teeth and gums.
Teeth grinding (or clenching) is the involuntary movement of the jaws when not engaged in normal functions like chewing, speaking or swallowing. The action often produces higher than normal chewing forces, which over time can accelerate tooth wear, cause fractures, or contribute to loose teeth, all of which could increase the risk of dental disease. While it can occur at any time it’s most common among children during nighttime sleep.
While stress is the usual trigger for teeth grinding in adults, with young children the causes for the habit are more complex and less understood. Most doctors hold to the theory that most pediatric teeth grinding arises during shifts from lighter to heavier, rapid-eye-movement (REM) sleep. The child’s immature neuromuscular chewing control may engage involuntarily during this shift. Teeth grinding is also prevalent among children who snore or mouth-breathe, or who take anti-depressant medication.
But as mentioned before, there’s usually no cause for concern unless the habit persists beyond about age 11. If the habit isn’t fading, you should speak to your dentist about ways to reduce it or its effects. One way is with a custom-made night guard worn during sleep. The smooth, plastic surface of the appliance prevents teeth from making solid contact with each other during a grinding episode.
You might also seek treatment from an ear, nose and throat (ENT) specialist if your child is having issues with airway obstruction, which could also relieve teeth grinding. And children experiencing stressful situations or events may find relief both emotionally and physically from psychological therapy.
At younger ages, you can safely regard your child’s grinding habit as normal. But if it persists, it’s worth looking for ways to reduce it.

One of the unfortunate aspects of aging is tooth wear. Depending on your diet, years of biting and chewing can cause enamel along the biting surfaces to erode. Your body also can't replace enamel — so when it comes to teeth it's not a question of if, but how much your teeth will wear during your lifetime.
To make matters worse, certain conditions cause tooth wear to accelerate. Teeth softened by acids or tooth decay, for example, erode faster than healthier teeth. So will grinding habits: often fueled by stress, these include chewing on hard items like nails, pencils or bobby pins.
You may also grind your teeth, usually while you sleep. Normal biting and chewing produces pressure of about 13 to 23 pounds per square inch: grinding your teeth at night can well exceed this, even up into the hundreds of pounds.
There are some things we can do to alleviate these issues. For clenching and grinding habits, one primary step is to address stress through counseling or biofeedback therapy. For nighttime teeth grinding we can create a bite guard to wear while you sleep that will prevent your teeth from generating abnormal forces.
Finally, it's important that you take care of your teeth through daily oral hygiene, regular office cleanings and checkups, and a nutritious diet for maintaining strong bones and teeth. Keeping your teeth free from diseases that could compromise your enamel as well as other aspects of your mouth will help them stay as strong as possible.

While tooth decay and periodontal (gum) disease destroy more teeth than any other causes, both of these diseases are largely preventable with proper oral hygiene and dental treatment. It’s more than possible, then, to enjoy a lifetime of healthy, disease-free teeth.
But even with healthy teeth, the effects of aging will cause tooth wear over time. And although we can’t prevent the aging process from occurring altogether, there are steps we can take not to accelerate the process.
Most tissues, including bone and teeth, have a growth cycle in which older cells are broken down (known as catabolism), removed and replaced by newer cells (anabolism). As we develop during childhood, the growth phase exceeds breakdown; when we reach adulthood, the two phases come into equilibrium. But as we age, breakdown will gradually overtake growth. This aging effect results in, among other outcomes, tooth wear.
“Normal” wear appears to be greatest — and most visible — along the biting surfaces of the teeth. The forces generated when we bite or chew causes enamel to erode over time. Unfortunately, you can accelerate this process through bad oral habits: clenching or grinding teeth, often times at night while you sleep, as well as habitually chewing on hard objects like nails or pencils.
Normal forces generated when we bite or chew are actually beneficial for dental health — they help stimulate bone growth. But when they exceed their normal range as when we clench or grind our teeth, they can increase tooth wear and cause other problems such as diminished function or changes in appearance, such as a shortened facial height.
To slow the rate of wear, it’s important to modify any behaviors that may be contributing to it. In many cases an occlusal night guard worn while you sleep helps prevent teeth clenching. You may also need assistance with stress management, a major trigger for these kinds of habits, through biofeedback therapy or counseling.
If you’ve already encountered excessive wear, bonding techniques using colored composite resin, veneers or crowns that attach directly to the teeth can restore lost function and rejuvenate the appearance and color of your teeth. We can perform a “smile analysis” to determine if one of these techniques is right for you to help you regain a more youthful and attractive smile.
