A bridge is like a series of connected crowns, some of which fill the space left by missing teeth and some of which sit on existing teeth and protect them.
A bridge may be an option when one or more missing teeth need to be replaced.
It is cemented or bonded in place so you may not even notice that it's there. You may feel like you have your natural teeth back; many patients do. It is typically more economical than an implant and has many of the same advantages.
