Crowns and Bridges
As teeth age, they develop cracks and stress fractures which increases the need for a crown. Silver fillings are held in the teeth due to mechanical retention; over time the metal microscopically expands and contracts, allowing leakage around it for more decay to start. Today’s tooth colored fillings are bonded into place and do not have the expanding or contracting at the rate silver fillings do. However, sometimes crowns are the more conservative treatment over very large fillings, especially when the cusps (corners) of the tooth are compromised; the more dental work a tooth has and the deeper the decay gets to the nerve, the higher the chance for root canal treatment is. Crowns wrap around the entire tooth and are cemented in place; they are a more long-term restoration than a very large filling. Bridges are crowns joined together to replace missing teeth. Today with the success of implants we are making fewer bridges. We typically make all zirconium crowns but offer other types of lab made crowns as well.
