teeth grinding
Why does my child grind their teeth?
Teeth grinding (bruxism) is very common in young children and usually harmless — often linked to new teeth, jaw growth, tiredness, tension, or sensory regulation, and most children grow out of it. Check with a dentist or doctor if it causes worn teeth, jaw pain, or comes with disturbed sleep, and consider a developmental check if it sits within wider sensory or regulation concerns.
That night-time grinding sound can be unsettling to hear — but in most young children it is far more common, and far less worrying, than it feels.
In short
Teeth grinding (clinicians call it bruxism) is very common in childhood — many children do it, especially during sleep, and most simply grow out of it as their adult teeth settle in. Common reasons include new teeth coming through, the natural way jaws line up while growing, mild discomfort, or a way of releasing tension and big feelings. Once in a while, persistent grinding goes alongside sensory needs, disrupted sleep, or stress — which is worth a gentle look. It is a symptom to understand, not a diagnosis to fear.Why it happens
Most grinding falls into a few everyday patterns:- Growth and teeth — emerging or shifting teeth, and the jaw finding its natural bite, often trigger grinding that fades with time.
- Sensory regulation — for some children, the firm pressure of clenching or grinding is calming; it can be a way the body seeks input, much like chewing or fidgeting.
- Tension and tiredness — excitement, worry or an overtired body can show up as night-time grinding.
- Sleep and breathing — disturbed sleep, mouth-breathing or blocked nasal airways can be linked, so it is worth mentioning to your doctor or dentist.
When to have a closer look
Most grinding needs only reassurance and time. Do check in with a dentist or your child's doctor if you notice: worn, chipped or sensitive teeth; jaw or face pain on waking; ongoing daytime grinding; or grinding alongside snoring, restless sleep or daytime tiredness. If grinding sits within a wider picture — strong sensory-seeking, big regulation struggles, or other developmental questions — a developmental check helps you see the whole child, not just the symptom.The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online description or a worried night's listening. If grinding seems tied to sensory needs or regulation, our team can map the full picture through a structured, clinician-led assessment and gentle occupational and sensory therapy where it helps. Start by understanding the symptom itself at teeth grinding.Trusted sources

What to watch
Worn, chipped or sensitive teeth; jaw or facial pain on waking; ongoing daytime grinding; grinding alongside snoring, restless sleep or daytime tiredness; or grinding paired with strong sensory-seeking or regulation struggles.
Try this at home
Build a calm wind-down routine before bed — dim lights, quiet play and a warm bath can ease tension. Offer safe firm-input options in the day (a chewy snack, a chewable toy) if your child seems to seek that pressure.

Frequently asked
Is teeth grinding in children normal?
Yes — it is very common, especially during sleep. Many children grind their teeth at some point, often linked to new teeth, jaw growth or tiredness, and most grow out of it without treatment.
Can teeth grinding be a sign of stress or sensory needs?
Sometimes. For some children the firm pressure of grinding is calming and a way to seek sensory input, while excitement, worry or being overtired can also play a part. If it sits within wider regulation struggles, a developmental check helps.
When should I worry about my child's teeth grinding?
Check with a dentist or doctor if you see worn, chipped or sensitive teeth, jaw or face pain on waking, ongoing daytime grinding, or grinding alongside snoring, restless sleep or daytime tiredness.
Does teeth grinding damage my child's teeth?
Occasional grinding rarely causes lasting harm, especially with baby teeth. Frequent, forceful grinding can wear or chip teeth over time, so a dentist can check and advise if you notice changes.
