Does Your Child Grind Their Teeth? It Could Be an Airway Issue

Teeth grinding — also called bruxism — is common in children. Many parents assume it’s just a phase.

But sometimes, grinding can be a sign of something deeper.

At Alpine Pediatric Dentistry in Lincolnton, NC, we evaluate teeth grinding as part of a comprehensive pediatric exam — especially when airway concerns are present.

Why Do Children Grind Their Teeth?

Common causes of teeth grinding include:

• Stress or anxiety

• Teething discomfort

• Bite alignment changes

• Airway obstruction

While occasional grinding is normal, persistent or loud grinding may signal disrupted breathing during sleep.

The Airway Connection

When a child’s airway is partially restricted during sleep, the body may instinctively shift the jaw forward in an attempt to open the airway.

That movement can result in grinding.

Teeth grinding may be associated with:

• Snoring

• Mouth breathing

• Restless sleep

• Nighttime sweating

• Daytime fatigue

If grinding is paired with these symptoms, further evaluation may be helpful.

Signs Grinding May Need Evaluation

• Loud, frequent nighttime grinding

• Worn or flattened teeth

• Jaw discomfort

• Headaches

• Poor-quality sleep

Families throughout the greater Charlotte area often seek evaluation when grinding persists beyond early childhood.

What Happens During an Airway-Focused Evaluation?

We assess:

• Breathing patterns

• Tongue posture

• Jaw development

• Tonsil size (visually)

• Overall oral growth

In some cases, we may recommend monitoring, collaboration with a pediatrician or ENT, or additional airway-focused strategies.

Not all grinding is airway-related — but understanding the root cause allows for the most appropriate care.

Healthy sleep supports healthy growth — and sometimes grinding is the body’s way of asking for help.
