The best night guard for teeth grinding is one that fits well, stays comfortable all night, and holds up to your grinding. Here’s how the main options compare.
By the FixUrSmile Dental Lab team · Updated September 2026
Grinding or clenching your teeth during sleep (sleep bruxism) can wear down enamel, chip teeth, and damage dental work. A night guard puts a protective layer between your upper and lower teeth. It doesn’t cure grinding, but it helps protect your teeth from the wear it causes. If you have jaw pain, headaches, or TMJ symptoms, see a dentist to find the cause.

The FixUrSmile Custom Night Guard is a hybrid design: soft inside for comfort, durable outside for protection.
Many providers recommend replacing a night guard every 3 to 5 years, or sooner if it cracks, gets holes, discolors, or no longer fits, according to GoodRx. Heavy grinders may need replacements more often. Keeping it clean helps it last. See how to clean a night guard.

For many people, yes. Custom guards are slimmer, more comfortable, and more durable than boil-and-bite guards because they’re made from impressions of your teeth.
Soft guards suit light grinding, hard guards suit heavy grinding, and hybrid guards with a soft inside and hard outside offer a balance of both.
Both can work. Many people wear an upper guard, but the best choice depends on your bite and comfort. Ask your dentist if you’re unsure.
A night guard protects your teeth from grinding damage, but it doesn’t treat the cause. Talk to your dentist or doctor about causes such as stress or sleep issues.
