HI BRYANNA,
Thanks for your quick reply to my worrisome problem! I understand the possibility of a 4 tooth bridge but was wondering if extraction of tooth 20 followed by an implant in its place as the new abutment for the three tooth bridge is a plausible solution to this problem. It seems this would eliminate the need for tooth 21 being shaped to serve as the new abutment. If this is feasible do you beleive my current crown could be modified to fit the implant abutment? Lastly what is your opinion of the "flexible dentures" as a possible solution following extraction of tooth 20?
