Deep, even breathing. Blankets softly rustling. The occasional sigh. These sweet sounds of children asleep are music to a weary parent’s ears — until the serenity is pierced by the unmistakable noise of grinding teeth!
When I tiptoed past my slumbering preschooler’s bedroom one night, I heard her peaceful sleep sounds shattered by the bone-rattling, fingernails-on-a-blackboard racket of her tiny teeth, gnashing away.
I lapsed into a moment of parental panic. Surely, this would damage her teeth! Did she do this every night? Was she overstressed? Should I wake her?
The grinding noises tapered off after a few minutes, but my questions continued.
Many parents will hear their children’s teeth grinding at some point. A study in Journal of Dentistry for Children found that more than a third of parents report the condition in their children.
“It can get pretty loud,” admits Dr. Paul Bussman, spokesperson for the Academy of General Dentistry.
Though teeth grinding, or bruxism, may be alarming or worrisome, it’s generally a normal part of the growing process, he says.
Grinding can begin in babyhood — as soon as children have teeth to grind — and generally starts to subside as the permanent teeth begin to erupt, says Dr. Bussman. The condition commonly disappears on its own in childhood, but a small percentage of kids will continue to grind as adults. Severe or persistent grinders may suffer facial pain, ear aches, jaw-joint disorders, damaged teeth, and disturbed sleep.
According to Dr. Khaleel Ahmad of the Iowa Sleep Disorders Center, researchers haven’t pinned down a cause for bruxism. Genetics may play a role — if either parents grinds their teeth at night, children are 1.8 times more likely to grind their own.
Daytime stress and medicines like amphetamines have been associated with bruxism. Interestingly, nearly a third of grinders also bite their nails, and more than 20 percent suck their thumbs, says Dr. Ahmed.
If your child’s teeth have become nighttime noisemakers, here are some tips for coping:
“Don’t wake a child engaged in nighttime teeth grinding,” says Dr. Bussman. “They’re not aware of it, so bringing it to their attention will probably confuse them.”
Grinding can be associated with daytime stress, so help kids relax. Ask them to talk about any stressful events they may have encountered during their day, and encourage them to unwind in the hours before bedtime with a bath, books, and quiet activities.
Help your child maintain good sleep habits, with an age-appropriate bedtime, a regular bedtime routine, and a cool, dark, quiet, and comfortable sleep environment.
Bruxism occurs more commonly during back sleeping. The American Academy of Pediatrics recommends back sleeping for infants, but older children who grind may be more comfortable sleeping in another position.
Encourage kids to get adequate exercise. Physical activity helps kids fall asleep faster, promotes deep, restful sleep, and eases stress, which can contribute to teeth grinding.
As difficult as it may be, try not to become overly concerned with the occasional episode of bruxim. Dr. Bussman advises parents to turn down the volume on monitoring devices so they aren’t tuned in to every little sound.
If grinding regularly interferes with sleep or if a child complains of pain in his teeth or face, see a dentist. In severe cases, a dentist may prescribe a nightgaurd made of soft plastic to protect the teeth and the jaw joint. Occasionally, grinding is associated with a misaligned bite. If that’s the case, a pediatric dentist will refer your child to an orthodontist.
Thankfully, my little bruxist has eased up. But if I hear more teeth-gnashing noises coming from her room, I’ll be better prepared — and I’ll worry a lot less.
