What is the primary purpose of a dental crown?

The primary purpose of a dental crown is to protect a weak tooth. Crowns are designed to encase the entire tooth structure above the gum line, providing strength and support to teeth that have been compromised due to decay, trauma, or large fillings. By covering the tooth, crowns help prevent further damage and reduce the risk of fracture, effectively maintaining the tooth's functionality.

While enhancing the appearance of teeth, supporting dental bridges, and whitening discolored teeth are important aspects of dental treatments and procedures, they do not capture the primary function of a crown. Crowns can certainly improve tooth aesthetics and work in conjunction with bridges, but their essential role lies in protecting and preserving the integrity of weakened teeth.
