DenTek Ultimate Dental Guard, Slim-Fit Mouth Guard for Grinding Teeth at Night, FDA Cleared Night Guard, 1 Count

As many people have said, a mouth guard is the way imo. I chewed/clenched through tons of guards including the custom one from a dentist and almost gave up.... HOWEVER, I am a huge supporter of this over the counter one: https://a.co/d/059nNUXs I've bought a new one of this kind probably 5 or 6 times in the last few years because they get worn and gross, but I have NEVER fully bit through this mouth guard unlike so many others I've tried.
