Dental fillings are not reimbursable by health insurance. Most of the operations in dentistry are outpatient, and inpatient medical insurance does not start the reimbursement, and the materials used for fillings are mostly imported resin, so it is difficult to use the money from the medical insurance card, so patients need to pay in cash for fillings. The cost of filling varies according to the choice of filling materials, from 150-450 RMB, even the good ones can reach about 900 RMB, and the more expensive the material, the less the possibility of the balance of the medical insurance, because the imported materials are not considered to be the scope of treatment. However, if tooth decay occurs, it should be treated by filling in time, if it is not treated in the early stage and develops to pulpitis, the cost of treatment may be doubled.
