Crowns and bridges are dental restorations used to repair and replace damaged or missing teeth. A crown, often made of metal, porcelain, or a combination of materials, is placed over a damaged tooth to restore its shape, size, and strength, and to improve its appearance. A bridge, on the other hand, is used to fill the gap created by one or more missing teeth. It consists of artificial teeth anchored by crowns on the adjacent teeth or implants. Both crowns and bridges help restore functionality, prevent shifting of surrounding teeth, and enhance the overall smile. Regular dental care ensures their longevity.
