Frequently Asked Questions
Can a night guard make TMJ worse?
Yes, a poorly fitted or overly thick night guard can worsen TMJ by altering your bite. Our tests showed the Pro Teeth Guard's ultra-thin 1.55mm profile minimizes bite disruption, making it the safest choice for TMJ sufferers.
Should I get a soft or hard night guard for TMJ?
Dentists generally recommend hard acrylic for TMJ because soft guards can encourage more clenching and chewing. In our tests, The Doctor's NightGuard (Shore A 88) offered the best balance for light-to-moderate TMJ.
