i recently got new retainers to replace my old ones which were 10+ years old. I wore the top only for a first couple of days because the full set didn't feel to align properly/wasn't comfortable. But several nights later i noticed that my bite on one side is now lower. i suspect that the retainer was not aligned properly with my bite and led me to grind down slightly on one side in my sleep. i want to avoid doing the "bite adjustment" on the normal side as much as possible. is there a way to restore the lower side to match my original bite? i am starting to have jaw pains on the lower side due to this uneven height.
