So, my teeth are definitely moving...a lot. My braces are rubbing new holes all over the place. I had to go stock up on wax again. I should've snagged the free stuff from my ortho last week but didn't think I needed it. Anyway, one of the spots where the surgical hook is rubbing has now turned into a canker sore. This product looked like it could do the trick. These are the weirdest things I've ever seen. You stick this disc (that isn't much thinner then a Skittle) on the sore until it adheres itself to your mouth. It then dissolves and numbs the area. It didn't take long for it to stick to my braces and lodge itself on a bracket. I think I"ll stick to Zilactin from now on. Just a helpful hint for all the metal mouths out there.
