The lst one wants to remove 4 bicuspids for my severe crowding. The 2nd orthodontist told me that I wouldn't need extractions and that all I would need is to expand the jaw to make room for the teeth. The 1st orthodontist said that my case can't be done w/o extractions because of lack of bone to move things around. He said if I got work like that done I'd look fine initially but in 5-10 yrs, it would push my teeth out of the bone and I would have severe gum disease. Help! What should I do?
