Dental crowns are custom-made caps placed over damaged or decayed teeth to restore their shape, size, strength, and appearance. They are commonly made from materials such as porcelain, ceramic, or metal, blending seamlessly with natural teeth. Crowns are used in various dental treatments, including after root canals, to protect weakened teeth, or to improve the aesthetics of a discoloured tooth.

The procedure typically involves filing down the affected tooth, taking impressions for the crown, and placing a temporary crown until the final one is ready. With proper care, dental crowns can last many years, contributing to improved oral health and function.
