The experience with the Dr. was great, but a year and a later (after the warranty expired) I started getting holes in my snap on smile. I called their office and I asked how to repair the holes. The told me they could not be repaired and my only recourse is to buy another - For $1875.
The most important thing that affects the outcome when choosing Invisalign is patient compliance...Wearing the trays as instructed as well as wearing the retainers after the Invisalign is finished...If the patient chooses not to wear the retainers, the teeth will most likely move..Hope this helps answer your question!
