Post progress here.
Saw my orthodontist on Thursday to get aligner 4 and have some IPR and attachments put on. He said he was really happy with how my teeth are moving, and said he thought I don't need the attachments at all!!! I'm so happy! Aligner 4 is going well, was a bit tighter than the others, but my teeth are really starting to take shape! I also asked him to show me my final aligner, and it looks so good that its motivated me alot to carry on!!!
