Dental fillings play an indispensable role in modern dentistry, serving as a fundamental treatment for restoring teeth damaged by decay and preventing further deterioration. This procedure involves removing the decayed portion of the tooth and filling the cavity with a variety of materials, such as composite resin, amalgam, porcelain, or gold. By sealing off spaces where bacteria can enter, fillings help avert additional decay and provide structural support, thereby maintaining the tooth’s integrity and functionality. Moreover, advancements in dental materials and techniques have enabled fillings to closely match the natural color of teeth, offering not only restorative benefits but also aesthetic appeal. Dental fillings exemplify how traditional dental practices have evolved to meet the dual demands of health and aesthetics in oral care, making them a cornerstone of dental health maintenance.
