Hearing a grinding or grating sound coming from your child’s room at night can be startling, especially the first time it happens. Nighttime teeth grinding, known as bruxism, is common in children and can occur while their teeth and jaws are still developing. In many cases, the habit fades on its own as a child grows and their bite changes.
A little grinding now and then may not cause any problems, but frequent grinding can wear on the teeth or leave your child waking up with a sore jaw or a headache. Those are good things to mention at their next visit with Pediatric Dentistry of San Jose. If their teeth need some protection in the meantime, a custom pediatric mouthguard may be an option.
Why Do Kids Grind Their Teeth at Night?
Bruxism tends to show up during two periods of growth: when baby teeth first come in and again when permanent teeth begin to replace them. According to HealthyChildren.org, from the American Academy of Pediatrics, teeth grinding is common in toddlers and preschoolers and can begin even before a child’s first birthday, though most children outgrow it over time.
Beyond teething, grinding can be tied to stress, a change in routine, a new sibling, or a mouth breathing pattern caused by allergies or a stuffy nose. An uneven bite can also play a role, since the jaw sometimes grinds down high spots without your child ever being aware of it. Some children grind more during exciting weeks too, such as starting a new school year or getting ready for a trip, since young bodies often process big feelings through small physical habits. Most of the time, this pattern settles down once permanent teeth are in place and the jaw finishes developing, so there is rarely a reason to worry right away.
Signs Your Child May Be Grinding
Since grinding usually happens during deep sleep, many parents only notice it by accident, often from another room or during a late-night check-in. A few signs worth watching for include:
- A scraping or grinding sound while your child sleeps
- Complaints of a sore jaw or headache in the morning
- Teeth that look flattened, chipped, or more sensitive than before
- Restless sleep or frequent waking during the night
If you notice more than one of these signs, or the grinding sounds especially loud and frequent, it is a good time to schedule a checkup so we can take a closer look at your child’s teeth and bite.
How We Can Help Protect Your Child’s Smile
Regular visits for pediatric exams and cleanings give us the chance to catch early signs of wear before it becomes a bigger problem. During a checkup, we look at your child’s bite, gums, and enamel for signs of grinding, and we will talk with you about habits at home that could be contributing to it. These visits also give us a baseline for your child’s smile, which makes it much easier to spot small changes early rather than after months of unnoticed wear. If mouth breathing or thumb sucking seems to be part of the pattern, our guide to bite habits in children walks through what to watch for at home.
If grinding is frequent or causing visible wear, a custom-fitted night guard shields your child’s teeth while they sleep. Unlike over-the-counter options, a custom guard is molded specifically for your child’s mouth, so it stays comfortable and stays in place through the night. If an uneven bite seems to be part of the picture, we may also discuss whether an orthodontic evaluation makes sense down the road, since addressing the bite itself can sometimes ease grinding.
