Were your teeth very crooked? If you don’t mind me asking

honestly my teeth are/were a mess, crowded, overbite, you name it, Ive got it
very happy with my ortho tho, if you are uncomfortable with your teeth, go for it! 
Mine was complex. I needed a tooth removal, cross bite correction and had to work around an implant on a bridge and a veneer. I think it cost 3K in the end including 3 sets of Vivera retainers which was a much better price than my first quote of 5k min ( with tooth removal and retainers extra).
I needed almost as many trays in the 'refinement' stage than in the main treatment itself and it all took about 18 months ish but it was absolutely worth it for the difference it's made to my life.
