I have one question. I boiled my mouthpiece and did what the instructions said, but the mouthpiece is kind of loose. I mean I bite down on it as hard as I can, but when I stop biting, It falls from my upper teeth. I have tried boiling it and followed the instructions twice. Please help. I need to know whether just to leave it alone, or try it again. My teeth marks are already in the mouthpiece though.
