I've been diagnosed with bruxism (teeth grinding at night) and I made a custom mouth guard that attaches itself to the lower set of teeth. I can feel the pressure after wearing it for a night, but I made 3 mouth guards before and they all would fall out while I sleep. After a couple of month, I swear I can start to see the first 6 teeth at the bottom (canines to incisors) crowd more together. Is this just my imagination from the pressure I feel after the night wearing the mouth guard or can it really mean it's crowding my teeth, and possibly mean that I'll need braces to correct that?
