Bruxism

When you look in on your sleeping child, you want to hear the sounds of sweet dreams: easy breathing and an occasional sigh. But some parents hear the harsher sounds of gnashing and grinding teeth, called bruxism, which is common in kids. Bruxism is the medical term for the grinding of teeth or the clenching of jaws. Bruxism often occurs during deep sleep or while under stress.

No one knows why bruxism happens. But in some cases, kids may grind because the top and bottom teeth aren't aligned properly. Others do it as a response to pain, such as an earache or teething. Kids might grind their teeth as a way to ease the pain, just as they might rub a sore muscle. Stress — usually nervous tension or anger — is another cause. Some kids who are hyperactive also experience bruxism. And sometimes kids with other medical conditions (such as cerebral palsy) or on certain medications can develop bruxism.

Many cases of bruxism go undetected with no adverse effects, while others cause headaches or earaches. In some circumstances, nighttime grinding and clenching can wear down tooth enamel, chip teeth, increase temperature sensitivity, and cause severe facial pain and jaw problems, such as temporomandibular joint disease (TMJ). Most kids who grind, however, do not have TMJ problems unless their grinding and clenching is chronic.

Most kids outgrow bruxism, but a combination of parental observation and dental visits can help keep the problem in check until they do. In cases where the grinding and clenching make a child's face and jaw sore or damage the teeth, dentists may prescribe a special night guard. Molded to a child's teeth, the night guard is similar to the protective mouthpieces worn by football players. Though a mouthpiece may take some getting used to, positive results happen quickly.

Childhood bruxism is usually outgrown by adolescence. Most kids stop grinding when they lose their baby teeth. However, a few kids do continue to grind into adolescence. And if the bruxism is caused by stress, it will continue until the stress is relieved.

Because some bruxism is a child's natural reaction to growth and development, most cases can't be prevented. Stress-induced bruxism can be avoided, however, by talking with kids regularly about their feelings and helping them deal with stress. Take your child for routine dental visits to find and, if needed, treat bruxism.
