Hello, i'm wondering what kind of bite i have, as you can see i wear a wire retainer on the back of my upper and lower front teeth, which i brgan to wear after i lost my removable retainers and my teeth moved as a result and this is to keep it from moving more. I have another reviv mouthgaurd on the way, the previous did not fit, will it work?
