Just a note on the NTI device, I had one of these for years as I am a bad grinder. After a while I noticed that my front teeth were not coming together any more when biting, and I could not force them together. It turns out it is known that for people that really force their jaws together, the NTI device actually changes and collapses the jaw joint, changing the pivot point of your whole jaw. I stopped using it, but the change is permanent. I had to have the dentist actually grind down my molars so that my front teeth could touch again. Beware.
