Q. Hello Dr Caplan I underwent Invisalign treatment on my lower teeth and was thrilled with the results.In my upper jaw, however, years ago I had an incisor tooth removed on the left but the right one was left to grow down (the tooth underneath was removed). Years later, as this tooth protruded, I had it crowned and also had three veneers on my front teeth, which are not brilliant. My front teeth are not symmetrical. I was wondering if you can have Invisalign treatment with crowns and veneers? Many thanks.
