I was recommended to go to Dr. Scaff for general dentistry, and for that I had no real issues. However, go to a proper orthodontist rather than get Invisalign through him. I am looking at redoing the treatment a few years after getting this done with him. Bottom line: he cut corners and didn't do things that were needed for my treatment to be successful.
Some examples of cutting corners: The impressions he made did not fit because the part covering one of my wisdom teeth was malformed, so he cut off that part of those trays and had me do the same for every subsequent tray. Then, sometime midway through my treatment my invisalign trays started to not fit snugly on my teeth. One of my canine teeth that it was trying to rotate slipped from its position so that the button on that tooth was not under its respective slot in the tray.
Without telling me what he was going to do, he took his dental drill out and shaved the anchor button off that tooth, then proceeded to reshape the edge of my tooth and round it off so it fits the tray! That only temporarily fixed the tray fitting problem, then it got worse and maybe a month later he redid impressions, but that canine tooth is still twisted.. later had issues with retainers..
