Because you guys were so incredibly helpful with my previous post, I’ve got one more thing to ask. Earlier this year, I had a bridge installed on my upper right side. The molar back there was so worn down that the whole procedure was a total nightmare—problems with it sticking, nerve issues, the works. However, once the bridge was finally in, I didn’t have any pain or sensitivity at all. But ever since I started Invisalign, that specific tooth has become extremely sensitive; I can’t chew on that side and I have to be super careful when brushing. I expected some soreness in the teeth they adjusted before the trays went in, but has anyone else dealt with sensitivity in teeth that weren’t bothering them before? I figured I’d check here before I call my dentist to complain
