Bruxism in Children – What Every Parent Should Know

Bruxism in Children: рave you ever noticed your child grinding their teeth during sleep? It might be bruxism, and yes — it’s more common than you think!

What is bruxism?
Bruxism refers to involuntary grinding or clenching of teeth, often during sleep. It affects up to 20–30% of children at some point, especially between ages 3 and 10.

What causes it?
It’s rarely due to dental issues alone. Research highlights multiple contributing factors:

• Stress & anxiety — Emotional tension or big life changes (starting school, new sibling, etc.)
• Sleep disturbances — Irregular sleep routines, nightmares, or poor-quality sleep
• Neurodevelopmental factors — More common in children with ADHD or sensory processing sensitivities
• Teething or dental misalignment — In some younger children

Most cases of bruxism in kids are temporary and harmless — many children outgrow it without intervention.

When to consult a pediatrician or dentist?

• Your child complains of jaw pain or headaches
• Grinding is loud and persistent
• Teeth show signs of wear or damage
• You notice disturbed sleep or daytime fatigue

What can help?

• Maintain a calming bedtime routine
• Address emotional stress with empathy and support
• Regular dental check-ups
• Avoid screen time before bed

Remember: Bruxism isn’t just “a bad habit” — it’s often a sign that a child’s body or mind is trying to cope with something. Recognizing it early can make a real difference
