Hi all

I started my invisalign treatment a month back, started my 3rd set of aligners yesterday. Got 29 for top and 30 for the bottom.
My dentist has never mentioned refinements. I just thought after the 60 weeks that would be it. My treatment isnt exactly cheap - does this mean I'm only getting half the job done? What exactly are refinements??
He did say I'll need to get some impressions done half way through. I guess I never knew the right questions to ask before I began treatment.
Having found this forum and reading some of the threads I'm worrying it's not going to be the fairytale ending I've been hoping for
