Upper vs. Lower Mouthguard: Which Is Right for You?

A mouthguard is typically worn on the upper teeth because they protrude further than the lower teeth, making them more vulnerable to impact during sports or teeth grinding. An upper mouthguard absorbs and distributes force, reducing the risk of fractures, lacerations, and jaw injuries.

Why the Upper Arch?

The upper teeth naturally extend beyond the lower teeth, creating a larger target for direct blows. A properly fitted upper guard covers the entire dental arch and cushions the teeth against both external impacts and internal forces from clenching.

When a Lower Guard Might Be Used

In certain cases—such as a fixed orthodontic appliance on the upper teeth, a severe gag reflex, or specific dental work—a dentist may recommend a lower mouthguard. However, the upper guard remains the standard for most athletes and bruxism patients.

Key Takeaway

For the vast majority of people, an upper mouthguard provides superior protection and comfort. Consult your dentist to determine the best option for your specific needs.
