Athletes know mouthguards are essential gear for protecting your smile. But like all gear, they're not invincible. Worn-out mouthguards can fail at the worst moment, leaving you vulnerable to painful dental injuries. Here’s how to know when it's time for a fresh one.

Follow the Replacement Timeline

  • Every sports season or at least annually: Most dental professionals recommend swapping out mouthguards each season or at minimum, once a year, to maintain optimal protection.
  • More often for heavy users: If you're frequently training or competing, even yearly might not be soon enough. Look to replace more consistently based on condition.

Watch for Wear, Damage & Fit Issues

Replacing a mouthguard isn’t just about time, it’s about condition.

  • Visible damage: Replace immediately if you notice cracks, tears, thinning, holes or material breakdown.
  • Fit has changed: If the guard feels loose, misaligned or less secure, it won’t protect properly.
  • After dental changes: A new filling, extraction, orthodontic work or even natural jaw growth can alter your bite. Anytime your bite changes, your mouthguard needs re-evaluating.

Hygiene & Comfort Matters

  • Odor or discoloration: Can indicate bacterial buildup meaning it’s time for a replacement.
  • Discomfort: If your mouthguard irritates gums, it’s no longer fit for use. Comfort matters!

Special Considerations

  • Children and teens: Because their jaws are still growing, replacements may be required more regularly. Check the mouthguard still fits securely and is comfortable.
  • Post-illness: Germs can linger even with cleaning, it’s best to replace a guard for hygiene reasons.
  • Chewing habits: Letting your guard get chewed on can deform it, replace your guard if this happens.

Why Prompt Replacement Matters
