Crown and Bridges
Crowns are used for the following reasons:
- Decayed, broken or cracked teeth need crowns in order for the tooth to remain functional (ability to chew), and to prevent the tooth from breaking down even further
- A tooth that has received root canal treatment will need a crown. Once root canal treatment is done on a tooth, the nerve and blood supply has been removed from that tooth, which causes the tooth to become very brittle and prone to fracture. A crown the covers the entire surface of the tooth protects the tooth from fracture.
- Large fillings that cover many surfaces of the tooth have a higher failure rate, so crowns are often a better option to maintain long-term results.
Crowns normally take two appointments.
First Appointment: We take impressions and create diagnostic models of your tooth. The area is numbed adn the tooth is prepared for the crown by removing any decay or fractured areas, and creating the ideal surface for your crown. The impressions and models are sent to a dental laboratory, where your crown is made. While the lab constructs the crown, you will wear a temporary crown made here in the office by either the dentist or a trained dental assistant.
Second Appointment: This appointment is about two weeks after the first appointment. The temporary crown is removed, and the custom crown is placed on your tooth to check for fit and aesthetics. After any necessary adjustments are made, the crown is permanently cemented into place.
The process for a bridge is very similar to that of a crown, it just involves more than a single tooth. Bridges are used to replace a missing tooth between two natural teeth that are still existing (see the photo above).
