If you’ve lain awake listening to your toddler grinding their teeth in the next room, you’re not alone — and it’s one of the most common things parents ask us about at check-ups. The sound can be unsettling, especially in the quiet of the night, but the reassuring news is that teeth grinding (known as bruxism) is very common in young children and most little ones simply grow out of it. Here’s what’s actually going on, and what’s worth keeping an eye on.
Teeth grinding in toddlers is very common
Grinding or clenching during sleep is something many toddlers and young children do, often without ever being aware of it themselves. It tends to happen during sleep rather than while your child is awake, and for most families it comes and goes over time as your child grows. Because it’s raised so often at check-ups, please don’t feel like you’re overreacting by asking about it — it’s a completely normal question to have.
Why does it happen?
There isn’t one single, definite explanation for why young children grind their teeth, and it can vary from child to child. Some of the things that may play a part include:
- A bite that’s still settling. As baby teeth come through and your child’s jaw and bite continue to develop, some grinding can simply be part of that process working itself out.
- The different stages of sleep. Bruxism in young children is often linked to normal sleep patterns, rather than anything happening during the day.
- Airway-related factors. Grinding can sometimes be connected to how a child is breathing during sleep. All of the general dentists consulting at Tooth Town are well versed in screening for airway-related signs as part of a regular examination, alongside everything else we assess — it’s simply one of the things we keep in mind, not something you need to work out yourself at home.
We deliberately haven’t listed stress or anxiety as a typical cause here — while it’s sometimes raised as a possibility for older children or adults, it isn’t usually the main explanation in toddlers, and we don’t want you worrying unnecessarily about your child’s emotional wellbeing because of a grinding habit. If you do have any concerns about how your child is feeling more generally, that’s always worth mentioning to us or your GP separately.
What’s worth mentioning at your child’s next check-up
Most toddler teeth grinding doesn’t cause any lasting problems and doesn’t need treatment. That said, there are a few things worth simply flagging next time you see us — not to self-diagnose, but so we can take a look and reassure you either way:
- Visible wear or flattening on your child’s teeth
- Your child complaining of a sore jaw or headaches, particularly in the morning
- Grinding that seems to be getting noticeably louder, more frequent or more intense over time
- Snoring, noisy or mouth breathing, or noticeably restless sleep alongside the grinding
Noticing one of these doesn’t mean something is wrong — it just gives us useful information to check at your child’s regular visit. As part of every check-up, all of the general dentists consulting at Tooth Town look at the fuller picture, including airway-related signs, so you don’t need to try to piece this together on your own.
What you need to do at home
For most families, the answer is reassuringly simple: nothing specific. There’s no home remedy or routine change we’d recommend based on grinding alone, and most children stop as they grow, their bite settles and their sleep patterns mature. Regular check-ups are the best way to keep an eye on your child’s teeth, bite and broader development over time, so any concerns — including anything airway-related — can be picked up early and calmly.
Frequently asked questions
Is teeth grinding bad for my toddler’s teeth?
In most cases, no lasting harm comes from it. Baby teeth are also naturally due to be replaced by adult teeth over time. If we do notice signs of wear at a check-up, we’ll talk you through what, if anything, is worth doing.
Should I wake my child up when I hear them grinding?
There’s no need to wake your child or intervene during the night. Grinding during sleep isn’t something they can control, and waking them isn’t necessary.
Does my toddler need a mouthguard or night splint?
Not routinely, and it isn’t something we’d suggest as a default for toddlers. If grinding is causing visible wear or is a genuine concern, your child’s clinician can discuss appropriate options with you at an examination, based on what they see.
Will my child grow out of it?
Most children do reduce or stop grinding as they get older, though timing varies from child to child. There’s no need to put a timeframe on it — we’re simply here to check in along the way.
Could grinding be linked to something else going on with my child, like breathing or airway concerns?
It’s possible, and it’s not usually cause for alarm. Grinding can sometimes be connected to how a child is breathing during sleep, which is exactly why all of the general dentists consulting at Tooth Town routinely screen for airway-related signs as part of every examination. Rather than trying to work this out yourself, the best approach is to mention anything you’ve noticed — like snoring or restless sleep — at your child’s regular check-up so it can be looked at in context with everything else.
When should I contact Tooth Town rather than waiting for the next check-up?
If your child develops ongoing jaw pain, headaches, or you notice sudden or significant wear on their teeth, it’s worth giving us a call so we can have a look sooner rather than waiting for the next scheduled visit.
What to do next
If your toddler grinds their teeth at night, in most cases there’s nothing you need to do right now — just mention it at their next regular check-up so we can take a quick look, including at any airway-related factors. If you’ve noticed visible wear, jaw soreness, snoring, restless sleep, or grinding that seems to be getting more intense, we’re happy to bring your child’s appointment forward. Book an appointment and our team will check in with you and your child, gently and without fuss.
