FAQ
Do I need a mouthguard for BJJ?
Yes. Even in no-gi training, accidental knee and elbow strikes to the jaw are common. A mouthguard protects teeth, jaw, and reduces concussion risk.
What thickness is best for BJJ?
1.6β2mm is ideal for BJJ β thin enough for easy breathing and communication while providing protection. Wrestling-style thick guards (4mm+) hinder breathing during rolls.
How often should I replace my BJJ mouthguard?
Replace every 6β12 months for regular grapplers, or sooner if you notice cracks, deformation, or persistent odors despite cleaning.
