Bridge placed and permanently cemented 2 weeks ago. At time dentist did not point out #13 tooth exposed under bridge. No pain, but concerned about life of bridge. Dentist only said will look better when guns heal, but will guns cover tooth or is bridge too small? Tomorrow sending 4 of 5 crowns back bc he wrongly perm cemented #7,saying fine but fluid gets in, pain, can't eat on it.Temp cement on 6,8,9 against their advice but color, size, shape wrong & different from wax up. Send all8 back?
