How do I know if I need a mouth guard for teeth grinding?

If you wake up with a sore jaw, notice tooth wear, or hear someone say you grind your teeth at night, a mouth guard may be worth asking about. NIDCR says dentists can check for signs of bruxism and may provide a custom-made mouthguard to protect the teeth from damage.

The important distinction is that a mouth guard protects teeth; it does not fix the cause. Stress management, sleep issues, certain medications, caffeine, alcohol, and jaw problems can all be part of the picture. If you have pain, cracked teeth, headaches, or jaw clicking, the right next step is a dentist, not just a random guard from the store.

Signs worth taking seriously include flattened tooth edges, chipped enamel, sensitive teeth, morning temple headaches, jaw soreness, and a partner hearing grinding at night. A dentist can also tell whether the wear pattern looks like grinding or something else, such as acid erosion or a bite problem.

For a temporary at-home option, look for a comfortable mouth guard for teeth grinding, but treat it as a stopgap until you know what is actually going on.

Do not ignore the basics while you wait for an appointment. A worn brush can irritate gums, so the toothbrush replacement guide is a useful maintenance check. If you are overdue for routine care, the annual checkup guide explains what preventive visits are for.
