If you're an athlete, you already know the importance of a sports mouthguard—it protects your teeth from impacts during games. But what about after the game? Many athletes don’t realize they also need a night guard to protect against something just as damaging: teeth grinding (bruxism).
In this guide, we’ll break down:
✔ Why athletes grind their teeth more
✔ How sports guards fail for nighttime protection
✔ The best night guard options for active individuals
Intense training increases cortisol levels, leading to jaw clenching.
Post-game adrenaline crashes can trigger nighttime grinding.
Wearing a sports guard for hours trains your jaw to clench.
This habit often continues even after removing it.
Contact sports increase risk of TMJ disorders, which worsen grinding.

💡 A sports guard won’t stop grinding—it’s like wearing cleats to bed!

💡 Use your sports guard for games, and a night guard for sleep.

Your teeth face two different battles:
Daytime: Impacts from sports → sports mouthguard
Nighttime: Grinding from stress → night guard
Don’t leave your smile half-protected.
Q: Can I use my sports mouthguard as a night guard?
A: No! It’s too bulky and not designed for grinding forces.
Q: Do night guards help with concussions?
A: No, but they prevent dental damage if grinding worsens post-injury.
Q: How do I clean my night guard after workouts?
A: Rinse with cool water and brush gently—avoid hot water (can warp it).
