My dentist mentioned Invisalign to me before but I did not research it until today. I searched their website and found that my practice with 2 dentists is a "Preferred Provider" whereas there is another practice in my area with 2 dentists that is listed as "Elite Preferred Provider" and also top 1%. Both are also orthodontists and apparently teens are seen in the practice as well (is this good or bad for their ability with adults? is it diffusion of effort or useful practice for adults?). Is it common for persons to see dentists for Invisalign that are NOT their regular dentist, and how have dentists reacted to this? Is there any reason I should not go to the one with more experience? I think my teeth are fairly straightforward (one tooth on the bottom that is posterior to the next but it's not visible from the front, only from the top, and one tooth on top that is slightly crooked) but I'd like the best result and someone who will take the time to answer questions. I also saw numbers from 2011 regarding how to attain the various designations, has this changed since then? 10 cases for Preferred seems quite low. Are prices usually comparable in the same geographic area? Thank you very much!
