Teeth grinding — known clinically as bruxism — is a condition that affects millions of people, often while they sleep. Many people are completely unaware they grind their teeth until a partner tells them or a dentist spots the evidence. Here is what you need to know.
What Causes Teeth Grinding?
Bruxism is often linked to stress and anxiety, though structural factors like a misaligned bite or certain sleep disorders (particularly sleep apnea) also play a role. Some medications, particularly certain antidepressants, can cause or worsen grinding. In children, it is often a normal developmental phase that resolves on its own.
The Damage Bruxism Can Cause
The forces generated by nighttime grinding can be far greater than those of normal chewing. Over time, bruxism can wear down tooth enamel, cause chips and cracks, lead to tooth sensitivity, damage existing restorations, cause jaw soreness, and contribute to TMJ disorder. The damage accumulates slowly but can be significant.
How a Night Guard Helps
A custom-fitted night guard creates a protective barrier between your upper and lower teeth. It does not stop the grinding reflex, but it absorbs and distributes the grinding forces to protect your teeth and jaw. Many patients also experience significant improvement in morning headaches and jaw soreness.
Custom vs. Store-Bought Night Guards
Over-the-counter guards are bulky, uncomfortable, and often do not fit well enough to be effective. A custom guard made from digital impressions at our Calgary dental office fits precisely and is far more comfortable to wear — which means you are actually more likely to wear it.
