I've never had ortho before, so I didn't have much to compare the treatment to... One of the things I love is the new way they're cutting the trays (they are cut a bit higher now). Before as they would become loose they would rub against my gum line. They're not anymore since the change which I love.
I'm set to be in treatment for about a year to a year in a half, and I'm already noticing a difference. So far it's definitely worth it. I'm set to have crowns placed after treatment, and I'm excited to get what I need from orthodontia from this prior to getting the other cosmetic work done.
