Teeth filling is a common dental procedure used to repair teeth damaged by cavities, minor fractures, or wear. During the treatment, the dentist removes the decayed portion of the tooth, cleans the affected area, and fills the space with a restorative material such as composite resin, glass ionomer, or amalgam. This helps restore the tooth’s shape, strength, and normal function while preventing further decay. Tooth-colored fillings are commonly used today because they blend naturally with the surrounding teeth and provide a durable, aesthetic result.
