Over the past 18 trays I've had with Invisalign out of 55, I've noticed that one teeth I have has a gap where my teeth does not fit the aligner well while my other teeth does. Even my orthodontist has noticed. She says that if the gap does not go away, I'm going to need to take another impression and start refinments. The thing is I don't want to wait for another few weeks for the Invisalign refinements to come in. I also feel Invisalign is a discomfort to me because I don't always have the time to brush my teeth after I eat. Can I ask my orthodontist if I can change to braces?
