If you’ve heard a strange grinding or grating sound coming from your child’s room at night, you’re not alone. Teeth grinding in children shows up more often than most parents expect, and for a lot of families around Mernda, South Morang and the wider Doreen area, it’s one of the first odd little habits they notice as their kids grow. In most cases it settles down on its own. But knowing what to look for, and when it’s worth getting checked, can save you a fair bit of worry.
Before We Get Started
- Teeth grinding, or bruxism, is common in young children and usually happens during sleep.
- Most kids grow out of it without any lasting issues.
- Watch for a grinding sound at night, jaw soreness, or teeth that look more worn than expected.
- Regular check-ups are one of the easiest ways to keep track of it.
What Is Teeth Grinding (Bruxism) in Children?
Teeth grinding, also known as bruxism, is when your child clenches or grinds their teeth together, usually without meaning to. It tends to happen during sleep, though some children do it during the day too, often while concentrating on something like homework or a puzzle. It’s especially common in toddlers and preschoolers and tends to ease off as they get older.
You might not even notice it in your own child at first. Often it’s a sibling sharing a room, a grandparent staying over, or a babysitter who mentions the sound before you’ve picked up on it yourself.
Teeth Grinding vs Clenching: What’s the Difference?
The terms get used a bit loosely, but there is a small difference. Grinding is when the teeth slide back and forth against each other, which is what causes that grating sound. Clenching is when the jaw muscles tighten and the teeth press together without much movement, so it’s quieter and easier to miss. Some children do one, some do both, and either can happen during sleep or while they’re awake and focused on something.
Common Signs Your Child Might Be Grinding Their Teeth
Every child is different, and grinding doesn’t always look, or sound, the same from one child to the next. Here’s what tends to stand out.
What You Might Notice at Night
- A grinding or grating sound while they sleep
- Restless or disrupted sleep
- Waking up complaining of a sore jaw or face
What You Might Notice During the Day
- Headaches, especially in the morning
- Teeth that look flatter or more worn than you’d expect for their age
- Sensitivity when eating something hot, cold, or sweet
If you’ve spotted one or two of these, try not to jump to conclusions. Plenty of kids show mild signs without it ever turning into a bigger issue.
Why Do Children Grind Their Teeth?
There’s no single cause, and it’s not always obvious why one child grinds their teeth and another doesn’t. A few things that may play a part include teething discomfort in younger children, new teeth coming through as their jaw develops, and everyday stress or bigger changes, like starting at a new children’s dentist, beginning kindergarten, or adjusting to a new sibling at home.
Some parents also notice a link between grinding and bedtime routines, particularly on nights when screen time runs later than usual or the evening has been a bit chaotic. Others notice it seems to flare up around the same time as a growth spurt, or when a new tooth is on its way in. That said, every child’s triggers are different, and for some kids it simply happens without any clear reason at all, which can be a little frustrating if you’re trying to work out what’s causing it.
Does Teeth Grinding Look Different in Older Kids?
Bruxism isn’t only something that shows up in toddlers. Some children keep grinding into their primary school years, and occasionally it starts later than you’d expect, sometimes around exam time, a big move, or other stressful stretches. The signs tend to be similar at any age, though older kids are often better at describing what they’re feeling, like a tight jaw in the morning or teeth that feel more sensitive than usual.
If grinding shows up for the first time in an older child, it doesn’t necessarily mean anything is wrong. It’s simply another reason to mention it at their next visit so it can be kept on the radar.
When Should You Get It Checked?
Because so many children grow out of grinding without any lasting effects, there’s no need to panic the first time you notice it. But it is worth mentioning at your child’s next check-up, particularly if you’re noticing jaw pain, disturbed sleep, or teeth that look worn down.
Regular visits make it much easier to track changes over time, since your dentist can compare how their teeth look now against previous appointments. If you’re not sure how often your child should be seeing a dentist, our guide on how often kids need dental check-ups covers what’s generally recommended for growing families.
What Happens at a Dental Visit for Teeth Grinding?
There’s nothing to be nervous about. A visit to check on teeth grinding is usually low-key and straightforward. Your dentist will have a look at the wear pattern on your child’s teeth, ask a few questions about their sleep and any habits you’ve noticed at home, and talk you through whether any follow-up is needed.
For most young children, the answer is simply to keep an eye on things at future general dentistry visits. Treatment is rarely needed at this age. Healthdirect Australia notes that young children who grind their teeth often grow out of it without any intervention at all, which lines up with what we see day to day.
If your child is a little anxious about dental visits in general, our approach to paediatric dental care is built around keeping things relaxed and age-appropriate, so a check-up feels more like a friendly chat than anything to dread.
Frequently Asked Questions
Is Teeth Grinding Normal in Young Children?
Yes, it’s quite common, especially in toddlers and preschoolers. Many families across Doreen, South Morang and Mernda mention it to us at routine check-ups, and in most cases it turns out to be nothing to worry about.
Will My Child Grow Out of It?
Most children do stop grinding their teeth as they get older, often once their adult teeth start coming through. Every child is different though, and results and timing vary between individuals, so it’s hard to put an exact age on it.
Can Teeth Grinding Damage My Child’s Teeth?
In some cases, ongoing grinding can wear down the surface of the teeth over time. This is one of the reasons regular check-ups matter, so any wear can be picked up early and monitored rather than left unnoticed for months.
Should I Get My Child a Mouthguard?
This depends on the individual child, and it’s worth discussing with your dentist rather than deciding at home. A mouthguard may be suitable for some children, particularly if grinding is causing noticeable wear, but it’s not something every child needs.
What Can I Do at Home to Help?
A calm, unhurried bedtime routine can sometimes help, particularly if grinding seems linked to stress or a rushed evening. If you’re concerned about your child’s teeth grinding, it’s worth booking them in for a check-up so we can take a proper look.
