Dental crowns, often called caps, are custom-made restorations that completely cover a damaged or decayed tooth. They restore the tooth's strength, shape, size, and appearance. Crowns can be made from various materials, including porcelain, ceramic, zirconia, and metal alloys, and are designed to blend seamlessly with your natural teeth. They are used to protect a weak tooth, restore a broken tooth, cover a dental implant, or hold a dental bridge in place.
