Bruxism — teeth grinding or clenching — is quite common in children, affecting an estimated 15-40% of kids at some point. The good news is that most childhood bruxism resolves on its own.
Why Children Grind Their Teeth
In children, bruxism is often related to the transition between primary and permanent teeth — the jaw and bite are constantly changing. Stress and anxiety play a role at any age. Sleep-related bruxism is also associated with sleep-disordered breathing in some children.
Signs Your Child May Be Grinding
The most obvious sign is an audible grinding sound during sleep. Other signs include: worn-down tooth surfaces (flat or shortened teeth), complaints of jaw soreness or morning headaches, tooth sensitivity, and disrupted sleep.
When It Is Not a Concern
Most children who grind their baby teeth stop before or when their permanent teeth come in. If the grinding is not causing significant tooth wear, jaw pain, or sleep disruption, watchful waiting is often the most appropriate approach.
When to Seek Treatment
If your child's grinding is causing notable wear on permanent teeth, jaw pain, frequent headaches, or significant sleep disruption, it is worth a thorough evaluation. We can assess the degree of wear and discuss whether a custom night guard or other intervention is appropriate. Contact Smileworks Dental in Calgary to schedule an evaluation.
