It is a sound that stops many parents in their tracks: a scraping, squeaking noise coming from your child’s bedroom in the middle of the night. Teeth grinding, known in the dental world as bruxism, is surprisingly common in children. If you have heard it, you are not alone, and in most cases there is no need to panic. Here is what parents in Orange and the east side suburbs should know about why kids grind, when it is a normal phase, and when it is time to have a dentist take a look.
How Common Is Teeth Grinding in Children?
More common than most parents expect. Studies suggest that 15 to 30 percent of children grind their teeth at some point, usually during sleep. It tends to show up in two waves: when baby teeth first arrive, and again when permanent teeth start coming in around age six or seven. Many children grind for a season and then simply outgrow it.
Because kids are asleep when it happens, most never know they are doing it. Usually a parent or a sibling sharing the room notices first.
Why Do Kids Grind Their Teeth?
There is rarely one single cause, and often several factors work together. The most common reasons include:
- – Teeth coming in: New teeth, whether baby teeth or permanent ones, can feel strange. Grinding can be a child’s way of exploring how their bite fits together.
- – A growing, changing bite: As the jaw grows and teeth shift, the bite does not always line up perfectly. The mouth sometimes responds with nighttime grinding.
- – Stress and big feelings: Children process stress physically. A new school year, a move, a new sibling, or even excitement about an upcoming event can show up as grinding.
- – Sleep issues: Grinding is more common in children who snore, breathe through their mouths, or have restless sleep.
- – Certain habits or sensitivities: Some kids simply have more active jaw muscles than others.
When Grinding Is Probably Fine
In many cases, childhood grinding is a passing phase that needs nothing more than monitoring. If your child grinds occasionally, has no complaints of pain, and their teeth look healthy at checkups, your dentist will likely just keep an eye on it. Most children outgrow the habit by the time their permanent teeth are fully in.
Signs that grinding is likely harmless include:
- – It happens only now and then, not every night
- – Your child wakes up rested and pain-free
- – No complaints of jaw soreness or headaches
- – Teeth show no visible wear at regular dental visits
When to Call the Dentist
Sometimes grinding does deserve a closer look. Reach out to your pediatric dentist if you notice any of the following:
- – Complaints of pain: Jaw soreness, face pain, earaches, or headaches in the morning can all point to grinding that is straining the jaw.
- – Worn, chipped, or flattened teeth: Your dentist can spot wear patterns on the chewing surfaces long before they become serious.
- – Tooth sensitivity: If your child suddenly avoids cold drinks or ice cream, enamel wear from grinding could be a factor.
- – Loud, frequent grinding: Grinding that happens most nights and is loud enough to hear across the house is worth mentioning at the next visit.
- – Sleep concerns: Heavy snoring or gasping alongside grinding should be discussed, since sleep quality and oral health are closely connected.
Because stress can play a real role in grinding, it also helps to think about your child’s daytime world. Calming bedtime routines, less screen time before bed, and space to talk about worries can all reduce nighttime jaw tension. For children who carry anxiety into the dental chair itself, our team offers gentle anxiety management approaches designed to make every visit feel safe and predictable.
What Parents Can Try at Home Tonight
While you are waiting for your next dental visit, a few low-effort habits at home can take pressure off a grinding jaw:
- – A predictable wind-down: A warm bath, a story, and lights out at the same time each night help the whole nervous system, jaw included, relax.
- – Cut the late-day stimulation: Caffeine hides in surprising places, including chocolate and some sodas, and evening screens keep young brains revved up. An earlier, calmer evening often means a quieter night.
- – A warm compress: If your child wakes with a sore jaw, a warm washcloth held to the cheek for a few minutes before school can ease the ache.
- – Hydration: A dry mouth and a tired jaw often travel together, so keep water flowing through the day.
One thing to skip: over-the-counter boil-and-bite mouthguards. Growing jaws change fast, and an ill-fitting guard can interfere with how teeth come in. If a guard is the right call, it should be a custom one made by your child’s dentist.
What Can a Pediatric Dentist Do?
If grinding is causing wear or discomfort, your dentist has options. A checkup can rule out bite problems or other causes, and in some cases a custom night guard may be recommended to protect the teeth while your child sleeps. More often, though, the plan is simple: watchful waiting, regular monitoring at each cleaning, and small comfort measures at home like a warm washcloth on a sore jaw before bed.
