On My 25th Tray of Invisalign and Top Tray Doesn't Fit?
I'm currently on my 25th tray with Invisalign. I haven't had any issues until now. I'm not able to change my upper tray, but the bottom fits fine. I contacted my orthodontist and they said to wear the new bottom set and wear the old top set and use the white "chewie" to kind of set the teeth into place. My question is how long should I be using the chewie to ensure that I will be able to eventually fit the top tray? Thanks!
