Fixed bridges are a non-removable option to replace missing teeth. They are comprised of two crowns affixed to neighboring – or anchoring teeth. The artificial teeth then span between then anchor teeth and replace the missing teeth. They are strong and durable but will need to be replaced after many years. These are good options for the replacement of a missing tooth if the “anchoring teeth” already require crowns, or if the area of the missing tooth is not a good candidate for a dental implant.
