Dental fillings are a common restorative dental treatment used to repair teeth affected by decay or damage. They involve removing the decayed or damaged portion of the tooth and filling the space with a suitable material. Fillings can be made from materials such as composite resin, amalgam, or porcelain. The process typically involves cleaning the tooth, applying the filling material, shaping it to match the natural tooth contours, and finally, polishing the filling for a smooth finish. Dental fillings restore the tooth’s structure, strength, and function while preventing further decay or damage.
