Partha Dental Clinic — Removing my original teeth unnecessarily

Address:

murali nagar

Doctor was told me that she was going to cover the space between two tooth but now she is telling that she won't cover space and will put another teeth
Then why did she removed my original teeth?
Even Though they will put another teeth but its not original and definitely in future that plastic teeth or some other teeth will definitely face some problem in future and will they do free check up and fix that teeth again?
