Help prevent further tooth decay. Dental fillings can help prevent tooth decay by sealing off the tooth so bacteria cannot enter. Fillings can also help prevent tooth loss. Restore a tooth to its original shape. When a cavity is present, the tooth can become misshapen. Dental fillings can help to restore the tooth to its original shape and give it a more natural appearance. Prevent further damage to a tooth. Once a cavity has formed, it is important to fill it as soon as possible. If left untreated, the cavity can continue to grow and cause further damage to the tooth. This may eventually require a root canal or even an extraction. Last a long time. Dental fillings are made from amalgam (a mixture of metals) or composite resin (a plastic-like material). These materials are strong and durable, lasting for many years with proper care. Simple and quick procedure. The procedure for getting a dental filling is relatively simple and quick. It’s usually accomplished in just one visit to the dentist, unlike other procedures like root canal treatments or dental implants that need 2-3 visits.
