This one goes without saying. Smiles direct is garbage. How many canted arches, class 3 bites, TMD, lack of widening, bit problems,.... are we going to put up with?!
Even Invisalign done by a true orthodontist is highly limited for arch widening.
Self-ligating braces is better. Yes, it's annoying for people to see. But what price are you willing to pay?
