Dental fillings are restorative treatments used to repair teeth that have been damaged by cavities, minor cracks, or wear. When tooth decay creates a small hole in the tooth, a filling is placed to restore the tooth’s structure and prevent further damage. Fillings help protect the tooth from bacteria while restoring its normal function and appearance.

The procedure begins with the dentist removing the decayed portion of the tooth using specialized dental instruments. Once the affected area is cleaned and prepared, a filling material is placed into the cavity to restore the shape of the tooth. Common filling materials include composite resin, porcelain, amalgam, and glass ionomer. Composite fillings are widely used because they match the natural color of teeth and provide a more aesthetic result.
