...are full coverage restorations that are used to cover a tooth that is likely to break, or is too broken down to be restored with a filling. They are most commonly done after root canal treatment, or when a large filling wears out. Teeth are subjected to tremendous pressures. Crowns ride over the weakened tooth, providing strength & protecting the tooth against breakage. A broken or cracked tooth is a far more serious matter & much more difficult to treat. Crowns prevent this, as well as making for a nice smile.
Traditionally it takes two appointments to restore a tooth with a crown. In the first, any decay is removed from the tooth & it is shaped to accept the crown. Then an impression is made of the tooth for use in fabricating a crown. Between the two visits the crown is made, usually of high-strength porcelain over gold alloy, all ceramic material, or gold. During this time a temporary crown is worn. In the second visit this temporary is removed, the permanent crown is adjusted as needed, & cemented in place. Second appointments are NOT NEEDED with CEREC-One Visit Dentistry.
Dental bridges have been used for centuries to replace missing teeth. Today, dental bridges are still considered a durable option for bridging the gap between a missing tooth and surrounding teeth. However, Implants are the most conservative route to go, if one qualifies. Both bridges and implants are pretty close in cost. Comprised of two anchoring teeth and a replacement tooth, dental bridges help prevent surrounding teeth from drifting out of position, improve chewing and speaking, and help keep your natural face shape in tact.
There are three types of dental bridges: 1) traditional dental bridges, 2) cantilever dental bridges, and 3) Maryland bridges. Traditional bridges have either dental crowns or dental implants on either side of the missing tooth, plus a replacement tooth, which is held in place by a post-like structure called a dental abutment. Cantilever dental bridges are used in cases where there are surrounding teeth only on one side of the missing tooth.
Maryland bridges are made of a specialized resin that is cemented to a resin meshwork and cemented to the enamel of surrounding teeth.
