I've finished 14 trays. My bonded retainers wont work on top teeth as bottom teeth keep hitting the glue or more glue is removed and it breaks. I've been 6 times with broken retainer in 3 weeks. Is this normal? Now she wants to glue half retainer and rely on the overnight retainer. I'm concerned my unbonded tooth will move as it has always been the worst one. Its a zig zag shape and sits mostly on roof of mouth with glue on the top of my teeth. I feel like my teeth are moving already.
