My student dentist had indicated that she thought I grinded my teeth
and so should get a night guard. I said that I doubted I would be able
to wear one because I am a very light sleeper and had trouble wearing
the teeth whitening thing that was made for me a few years ago.

So then I read you guys talking about NTI and I decided to ask her
about that.

So I did and she had never heard of it. She asked another student
dentist and he had never heard of it.

Then she asked the prof, probably 60 years old.

He looked puzzled and said it was for headaches. I said, "Yes, but
apparently some dentists are using them successfully for grinding
problems."

He said, "Maybe for short term use it might be okay, especially if
grinding is giving you headaches, but long term use will probably
cause the front teeth to protrude, and also it can cause problems in
the jaw, leading to TMJ or other problems." I can't remember exactly
what he said, but it was something like that.

In any case, he was very much against it.

Seemed to me that he really didn't know much about it, though and was
probably behind-the-times in his views on this.

But what about these assertions?

Personally, the cost of a night guard OR an NTI seems overpriced to
me, and I am leaning towards not getting either one. I really have no
proof or indication, that I grind all that much in the first place. I
have never had headaches much at all (until my recent sinus lift - see
my thread on that!). So I am skeptical about my need for any kind of
guard.
