Review (3/5): Not for people with over bite.
I like the idea of this product and I know this can work for some people....but it is not for everyone.
I have a bit of an overbite. And this is made for someone who dose not have a overbite. If the bite's pressure is not squarely one on top of the other then, the teeth push out forward a little with unequal force. So this can make your overbite worse. My top teeth got more sore than my jaw after a few days, which means it's begining to move my teeth out forward more. So I gave this to my friend, who has perfect teeth and she has no problems.
