I have always wanted to fix my teeth, and i finally was able to do that through smile direct. I slacked a little bit on the impression kit while I got dental work to prepare for my aligners. I had my approval within a week and my treatment plan within a week on September 23rd. I was given a 20 tray plan, 6 months treatment. I have always thought i would be in them for years because of how bad I think my teeth are. I have purchased my plan and would have my first trays within 21 days. Super excited to get them! My plan doesnt show noticeable changes until about 1/2 way through the treatment.
