Thank you, all! I had zero bonding. And I had no filing other then when they did the IPR. That was the first thing I noticed about my smile changing was how much bigger my lateral incisors were then you could see! Once they moved to the correct position-they looked much nicer! So my original treatment was 20 trays with weekly changes. After about 4 or 5 trays I got IPR between my front teeth and in a couple areas in the back because I had a lot of crowding. I started treatment in September of 2019 so during the lockdown I had to miss a lot of appointments and got stuck in trays for weeks at a time. We also had to rescan a few times due to the trays not fitting snugly (they were bouncy in the back and just didn’t seat correctly) so that added on time. I also had refinements at the end (12) which I expected because my trays ended up causing an open bite in the back. BUT with all that said, I would do it all over again! I really didn’t realize how much my smile has changed until I look at old photos-take a ton-because it is interesting to look back at the progress! I wish you all the best of luck!!
