Dental fillings are a common restorative treatment used to repair tooth decay or damage to the tooth. The filling material is placed in the cavity or area of the tooth that has been affected by decay or damage. The filling material can be made of different materials such as composite resin, amalgam, gold, or porcelain. The dentist will choose the best dental filling material based on the location and extent of the damage. The procedure involves numbing the area around the tooth to make it painless, then removing the damaged portion of the tooth and filling the area with the chosen material. Dental fillings are important to prevent further decay and to restore the function and appearance of the tooth. Regular dental check-ups can help detect cavities early before they cause significant damage to the tooth.
