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.
