I finished invisalign 3 years ago. But I was traveling recently and forgot to wear my invisalign retainer for about 6 weeks. I just put them back in, & my front 2 teeth hurt pretty bad and feel kind of loose. The invisalign fit over all my teeth fine, so I figured it's okay as long as I can bare the pain..? My question is: Is this really bad for my front 2 teeth ligaments to stretch this much at once, or is it okay since the invisalign do fit over the teeth and I just need to bare the pain?
