A Flexi Partial Was Recommended for Me Today

Greetings - My bridge has come loose and have actually come out of mu mouth quite often. Today my dentist recommended the above procedure. I am 44 and a type ll diabetic. This is for the back of my mouth. Extractions will have to be done. Is this safe for me? Any other alternative? Will it look natural? He said the shaved teeth underneath has nothing to hold onto anymore. Please help
