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.

Teeth are naturally strong and durable — if we can prevent or control dental disease like tooth decay or gum disease, they can last a lifetime. Still, teeth do wear gradually as we age, a fact we must factor into our dental care as we grow older.
Sometimes, though, the wear rate can accelerate and lead to problems much earlier — even tooth loss. There are generally four ways this abnormal wear can occur.
Tooth to tooth contact. Attrition usually results from habitual teeth grinding or clenching that are well beyond normal tooth contact. Also known as bruxism, these habits may occur unconsciously, often while you sleep. Treatments for bruxism include an occlusal guard worn to prevent tooth to tooth contact, orthodontic treatment, medication, biofeedback or psychological counseling to improve stress coping skills.
Teeth and hard material contact. Bruxism causes abrasion when our teeth regularly bite on hard materials such as pencils, nails, or bobby pins. The constant contact with these and other abrasive surfaces will cause the enamel to erode. Again, learning to cope with stress and breaking the bruxism habit will help preserve the remaining enamel.
Chronic acid. A high level of acid from foods we eat or drink can erode tooth enamel. Saliva naturally neutralizes this acid and restores the mouth to a neutral pH, usually within thirty minutes to an hour after eating. But if you’re constantly snacking on acidic foods and beverages, saliva’s buffering ability can’t keep up. To avoid this situation, refrain from constant snacking and limit acidic beverages like sodas or sports drinks to mealtimes. Extreme cases of gastric reflux disease may also disrupt your mouth’s pH — seek treatment from your medical doctor if you’re having related symptoms.
Enamel loss at the gumline. Also known as abfraction, this enamel loss is often caused by receding gums that expose more of the tooth below the enamel, which can lead to its erosion. Preventing and treating gum disease (the leading cause of receding gums) and proper oral hygiene will lower your risks of receding gums and protect tooth enamel.
