I had a friend in high school who was kind of gung-ho and claimed to have fixed a misaligned tooth by applying pressure with his finger in the desired direction for an hour every night before going to bed. According to him, this worked. I wonder if that is possible or if the teeth would undo the progress in the other 23 hours.
