Works great
I grind my teeth so bad at night that I wake myself up from the noise.  I bought this after breaking a porcelain crown. I like that this guard fits over the front teeth and prevents me from clenching and grinding my back teeth, and I don't wake up as often at night anymore.  I have a small mouth and and the guard is kind of loose even after two attempts at molding it.  I can remove it with my tongue, but it will stay in place if I leave it alone.  I wish this had included some kind of case.  Don't leave it on the nightstand because the cat will run off with it. :)
