Dental Guard SMARTGUARD Elite (2 Guards 1 Travel case) Front Tooth Custom Anti Teeth Grinding Night Guard for Clenching - Dentist Designed - Bruxing Splint Mouth Protector for Relief of Symptoms

I got this one to tide me over while I saved up for an official appliance from the dentist, and this one worked so well that I never got the dentist one! I very strongly recommend a front-teeth-only approach... You can't grind teeth that aren't touching!
