Crowns and Bridges
Both crowns and bridges are fixed prosthetic devices that are commonly used to improve dental comfort, appearance and alignments. They are unlike dentures, which are removable. Crowns are cemented onto existing teeth or implants. Both of these use the same materials, such as porcelain or ceramic, which are the most popular because they can be matched to the color of the surrounding teeth. Gold, metal alloys, acrylic and ceramic can also be used.
Crowns are used to cover a damaged tooth, kind of like a cap, also to improve appearance, shape or alignment. When doing a crown they first start with a temporary which are made from acrylic but are only in place until the actual crown is received from the lab.
The five types of crowns are the temporary, stainless steel and are used on baby teeth, metal crowns which can withstand biting and chewing longer, porcelain-fused-to-metal have an inner metal cast with porcelain baked over it, and the all ceramic/porcelain crown provide optimum aesthetic results.

A bridge is used when a person is missing one or more teeth and can prevent from the shifting of teeth. They’re cemented to the natural teeth or implants surrounding the area, these teeth are called abutments. Material wise, they are the same as crowns. There are four types of bridges that are used; traditional bridge which is the most common and have two abutments, cantilever bridge is when the bridge can only be supported from one side, Maryland bonded bridges are used for the anterior teeth, and the implant-supported bridge which is when implants are placed for the support.
Benefits of Dental Bridges:
- Restore the ability to chew/speak
- Maintain shape of face, prevent collapsing
- Prevent other teeth from shifting out of position
- Distribute the force of biting
