Tooth filling is a common dental treatment used to repair teeth that have been damaged by decay or cavities. The treatment involves the removal of the decayed portion of the tooth and filling the resulting space with a restorative material. After removing the decay, the dentist cleans the area and fills it with materials like amalgam, composite resin, gold, or porcelain. The chosen material is shaped to match the natural contours of the tooth and is hardened to provide strength and durability. Tooth fillings restore the tooth’s structure, prevent further decay, and contribute to maintaining oral health. The choice of filling material depends on factors like the location of the tooth and the patient’s preferences.
