Bruxism in Children: Real Symptoms, Causes, and the New 2026 Clinical Approach

Childhood bruxism is one of the most common reasons for consultation in pediatric dentistry, but also one of the most misinterpreted. For years, teeth grinding was thought to be the main sign, but today we know that bruxism goes far beyond nocturnal noise. New terms like bracing and thrusting are redefining how we evaluate this muscular activity, allowing for a more precise and useful diagnosis for clinical management.

In this article, you will find an updated guide to identify childhood bruxism from a modern perspective, integrating evidence, orofacial function, and neurodevelopment.

What is childhood bruxism, really?

Bruxism is not a disease, but an activity that can be rhythmic or tonic, occurring during sleep or wakefulness.
In children, this activity is often transient and can be influenced by neurological, respiratory, emotional, and functional factors.

Most importantly:
✔ Not every child who grinds their teeth has clinically relevant bruxism
✔ Not every child with bruxism develops wear
✔ Bruxism is a symptom, not a final diagnosis

New concepts: Bracing and Thrusting

1. Bracing

It is a prolonged clenching, usually quieter, where there is no dental contact or grinding. It can be associated with emotional tension, regulatory difficulties, or altered breathing patterns.

2. Thrusting

It is a mandibular thrust, sometimes lateral, that can generate repetitive and more visible movements.
In pediatric clinics, thrusting is more common in children with sleep disturbances or nocturnal breathing issues.

Why this differentiation matters:
Because the management of bruxism changes depending on the type of muscle activity. A child who clenches due to anxiety is not the same as one who thrusts their jaw due to a compromised airway.

Clinical signs that do matter

• Pain or discomfort upon waking
• Repetitive nocturnal noise
• Masseter tension
• Difficulty opening the mouth in the morning
• Frequent awakenings or restless sleep
• Nocturnal oral breathing
• Dark circles, fatigue, or irritability
• Poor sleep habits

Clinical myths we must abandon

❌ "All wear is due to bruxism"
→ In children, much of the wear is erosive, associated with reflux or acids.

❌ "A child who grinds needs a splint"
→ In pediatrics, splints are not a first-line treatment and are almost never indicated.

❌ "Bruxism is exclusively a dental problem"
→ It is multisystemic: nervous system, sleep, breathing, emotions.

When to intervene and what to do

Intervene when:

• There is recurrent pain
• There is sleep disturbance
• There is evidence of respiratory obstruction
• Bruxism affects quality of life

Recommended approach:

• Evaluate breathing and sleep
• Improve sleep hygiene
• Identify emotional factors or stress
• Coordinate with pediatrics, ENT, and speech therapy

Conclusion

Childhood bruxism requires an updated, functional, and transdisciplinary approach.
