Dental fillings are a common and effective treatment for tooth decay or cavities. When a tooth becomes decayed or damaged, a filling is used to restore the tooth's structure and prevent further decay. The procedure involves removing the decayed portion of the tooth and filling the resulting cavity with a material such as composite resin, amalgam, gold, or porcelain.

During the filling procedure, the dentist first numbs the area around the affected tooth with a local anesthetic. The decayed portion of the tooth is then removed using a dental drill or laser, and the resulting cavity is cleaned and prepared for the filling material. The filling material is then placed in the cavity and shaped to match the natural contours of the tooth.

Dental fillings are a relatively simple and quick procedure that can be completed in a single visit to the dentist. With proper oral hygiene practices and regular dental checkups, dental fillings can last for many years and provide a durable and long-lasting solution to tooth decay.
