You check on your child at night and hear it before you see anything, a scraping, grinding sound coming from somewhere near their pillow. It stops as soon as you get close. The next morning, your child has no idea what you’re talking about.
Teeth grinding can happen in children, and hearing it doesn’t automatically mean something is seriously wrong. At the same time, grinding that keeps happening, visible wear on the teeth, pain, or other symptoms are worth bringing up with a dentist rather than assuming it will simply pass.
What Is Teeth Grinding in Children?
Dentists call this bruxism. It covers two related behaviors. Grinding happens when teeth actually move or rub against each other. Clenching happens when the jaw muscles tighten forcefully, sometimes without much visible tooth movement at all. Some children grind mainly while asleep. Others clench or grind during the day, often without anyone noticing. Parents tend to pick up on nighttime grinding because of the sound. Daytime clenching is much easier to miss, since there’s usually nothing to hear.
Is Teeth Grinding Common in Kids?
It can show up at different points during childhood, sometimes tied to specific stages of dental development. Rather than relying on a specific percentage, it’s more useful to know this: the presence of grinding alone doesn’t tell you whether your child has a serious dental problem. A dentist looks at your child’s actual teeth, symptoms, stage of development, and overall health, not just the sound you heard through a bedroom door.
Why Do Kids Grind Their Teeth?
There isn’t always one clear answer. Normal changes as baby teeth loosen and permanent teeth come in can play a role. How a child’s upper and lower teeth meet can factor in too. Sleep-related patterns, general stress or emotional changes, certain habits, and other individual factors can all contribute. Stress isn’t the automatic explanation for every child who grinds, and grinding on its own doesn’t mean your child is anxious. In plenty of cases, the exact reason simply isn’t obvious, even to a dentist looking closely.
Can Baby Teeth Grinding Be Normal?
Children go through significant changes as their teeth and jaws develop, and some grinding during these stages doesn’t necessarily point to a problem. That said, it’s still worth mentioning frequent grinding at regular dental visits, particularly if you notice tooth wear, chips, pain, sensitivity, or jaw discomfort alongside it. Grinding in baby teeth isn’t automatically harmless just because the teeth are temporary.
Can Grinding Damage a Child’s Teeth?
It depends on how often it happens, how much force is behind it, and how long it continues. Possible signs of more significant wear include flattened tooth edges, worn chewing surfaces, small chips, changes in tooth shape, and in some cases sensitivity. Teeth naturally experience some wear over time, so noticing a small change doesn’t automatically confirm a serious grinding problem. A dentist can tell you whether what they’re seeing looks typical for your child’s stage of dental development or whether it’s worth watching more closely.
What About Permanent Teeth?
It’s worth mentioning grinding as permanent teeth start coming in, since those teeth are meant to last a lifetime, and repeated excessive wear deserves attention. This isn’t meant to cause alarm. The American Academy of Pediatric Dentistry notes that preliminary evidence suggests juvenile bruxism is often a self-limiting condition, meaning many children don’t carry it into adulthood. Early evaluation simply gives your dentist a chance to monitor tooth wear over time and catch anything that looks like it’s actually causing damage.
How Can You Tell If Your Child Grinds at Night?
A few clues tend to show up: hearing the grinding sound directly, your child waking with jaw soreness, complaints about tooth discomfort, morning headaches in some cases, visible wear on the teeth, or a dentist noticing wear patterns during a routine exam. None of these confirm bruxism definitively on their own. Plenty of these symptoms have other possible explanations too, which is exactly why an evaluation matters more than trying to piece it together at home.
Does Grinding Cause Jaw Pain or Headaches in Kids?
For some children, yes, clenching or grinding can lead to jaw muscle fatigue or general discomfort. The American Academy of Pediatric Dentistry lists dental wear, headaches, jaw dysfunction, and muscle soreness among the complications reported with childhood bruxism. Headaches in children have plenty of other possible causes though, so it isn’t accurate to assume grinding is behind every headache your child has. If your child regularly experiences jaw pain, headaches, or facial discomfort, it’s worth discussing with your dentist or your child’s pediatrician.
When Should Parents Be Concerned?
A handful of signs are worth a conversation rather than waiting to see if they pass:
- Visible tooth wear that seems to be increasing
- Repeated tooth chips
- Tooth sensitivity
- Jaw pain or soreness
- Frequent complaints of facial discomfort
- Grinding you hear regularly over a long period
- Difficulty chewing
- Changes in how the teeth come together
- Sleep concerns
- A child waking with pain
You don’t need to wait for severe symptoms before mentioning any of this to your dentist.
Does Every Child Who Grinds Need a Night Guard?
No. Children are still growing, and their teeth and jaws continue changing over time, which makes this a different conversation than it is for adults. A dentist should evaluate whether an appliance actually makes sense rather than a parent picking one up on their own. Adult night guards and generic store-bought options aren’t a universal solution for kids, and shouldn’t be treated as one. Our overview of occlusal splints covers appliance basics in more general terms, though children’s dental development means the same reasoning doesn’t automatically transfer over. What actually makes sense for a child depends on their age, whether baby or permanent teeth are involved, how much wear is present, their symptoms, their dental development, and the overall reason behind the grinding.
What Can Parents Do at Home?
Mention the grinding at your child’s regular dental visits, even if it seems minor. Pay attention to new symptoms rather than assuming everything is fine by default. Avoid jumping to conclusions about what’s causing it. If it’s helpful, jot down a simple note of when you notice symptoms, which can help your dentist spot a pattern. Beyond that, follow whatever your dentist actually recommends. Skip unproven home remedies for stopping grinding, and don’t try to get your child to consciously stop grinding at night. That’s simply not something a child can control while asleep.
What Will a Dentist Look For?
An exam typically covers wear patterns on the teeth, chips or cracks, how your child’s teeth are developing, how the upper and lower teeth meet, any signs of sensitivity, jaw comfort, and how things have changed since a previous visit. Your dentist is looking at the whole picture. One grinding sound you mentioned, or one slightly worn tooth, doesn’t automatically mean treatment is necessary.
How Is Childhood Teeth Grinding Managed?
It depends entirely on what your dentist actually finds. In many cases, the plan is simply to keep an eye on things during regular visits. Other situations call for closer evaluation if there’s significant wear, pain, or another contributing factor worth addressing. There’s no single approach that fits every child, and no guarantee that any particular approach will permanently stop the grinding itself.
Does Childhood Teeth Grinding Go Away?
For many children, yes, grinding fades out on its own as their teeth and jaws continue developing. For others, it continues longer or comes with symptoms that are worth monitoring over time. There’s no single timeline that applies to every child. The more useful question isn’t really whether you still hear grinding occasionally. It’s whether that grinding seems to be causing actual damage or symptoms worth addressing.

Frequently Asked Questions
Is it normal for kids to grind their teeth?
It can happen at various stages of childhood and doesn’t automatically mean something is wrong. Persistent grinding, visible wear, or symptoms like pain are still worth mentioning to a dentist.
Can teeth grinding damage my child’s baby teeth?
It’s possible, depending on how often and how forcefully your child grinds. A dentist can tell you whether the wear they’re seeing looks typical or worth watching more closely.
Does my child need a night guard if they grind their teeth?
Not necessarily. Whether an appliance makes sense depends on your child’s age, dental development, symptoms, and the amount of wear present, which a dentist should evaluate directly.
Will my child outgrow teeth grinding?
Many children do stop as their teeth and jaws develop further, though there’s no guaranteed timeline. What matters more is whether the grinding is causing noticeable damage or symptoms.
When should I take my child to the dentist about grinding?
If you notice increasing tooth wear, chips, sensitivity, jaw pain, changes in how their teeth meet, or if grinding continues regularly over time, it’s worth bringing up rather than waiting.
