Crowns and Bridges are fixed prosthesis. They are cemented onto existing teeth or implants, and can only be removed by a dentist.
A Crown is a tooth-shaped cap that is placed over a damaged tooth (like a helmet on the head). Sometimes tooth becomes so severely damaged due to reasons like decay, cracked teeth or trauma that the area is too large to restore with a traditional filling. When your teeth are severely damaged or root canal treated, nutrition and strength of the teeth are compromised. Therefore crowns are necessary as it fully encases the entire visible portion of a tooth that lies at and above the gum line. The goal of providing a crown to your damaged teeth is to bring back your natural smile and prevent further damage.
