A dental filling is a material that is applied to a cavity to fill it and get rid of the infection causing bacteria. With its help, a decayed tooth can be brought back to its original contour, functionality, and appearance. Before a filling is applied, the cavity will be cleaned and disinfected, thereby halting the spread of the cavity.
Fillings have been around for a long time now, which is why several options for filling cavities are available. Some of the most prominent ones are as follows:
Sometimes, applying a filling material to a large cavity can become too complicated due to the risk of tooth failure due to fracture. In other cases, the sealing wouldn’t be completed perfectly and could lead to re-infection. In such cases, inlays or onlays may be recommended by the dentist. An inlay is essentially a custom fabricated filling that fits perfectly in the cavity. It offers perfect sealing and restores the tooth to its original condition. An Onlay is a restoration that is used to restore the cusp, or biting surface of a decayed or worn-out tooth.
The dentist would initially screen the tooth to determine the extent of infection. Prior to starting the filling procedure, the cavity has to be disinfected. The decay will be removed and the walls of the cavity will be scrubbed to get rid of the microbes. Once it is disinfected, the filling material will be prepared. It will be made to match the exact color of the tooth, applied on the cavity and shaped accordingly. A special curing light will be used to harden the applied filling. Any adjustments, if required, will be made.
