this review title is: not for people with over bite and the content is: i like the idea of this product and i know this can work for some peoplebut it is not for everyonei have a bit of an overbite and this is made for someone who dose not have a overbite if the bites 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 is begining to move my teeth out forward more so i gave this to my friend who has perfect teeth and she has no problems.there are other information for this review, one is this reviewer did purchase it and the other is 3 people think this review is helpful.
