Tooth coloured fillings, or composite resins, have become very popular option to restore the back teeth. They look virtually identical to natural teeth. However, like all restorations that we place, they do have a lifespan. The longevity of a tooth coloured filling can depend upon many factors including type of material used, the chewing forces that are placed on the filling, grinding or clenching forces and an acidic oral environment.
Old composite resins fillings can sometimes fracture, creating a situation where decay can develop under the filling. The first picture illustrates a broken filling and a filling with decay underneath. The second picture shows the new restoration which is bonded to the tooth, creating a seal from the oral bacteria. This should serve the patient well for many years to come.
It is important to have your fillings checked by a dentist on a regular basis. If not, decay underneath a filling can go undetected and cause more serious problems.
