What are Dental Crowns?
Dental Crowns are used to repair badly decayed, broken or severely discolored teeth or teeth that are not properly aligned. A dental crown is an artificial covering for the tooth and can be made out of several different types of material. A dental crown can be zircon, porcelain, acrylic, gold or a combination of metal and porcelain or gold and porcelain. Where in the mouth the cap is being placed will determine the type of material used.
Dental Crowns look just like regular teeth and no one but you and your dentist will know which tooth is yours and which one is a cap. The tooth under the crown is reduced in size, over which the dental crowns will be permanently cemented. While the permanent dental crown is being fabricated you will be given a temporary crown to wear. Crowns have a much longer life span than bonding, resist stains better, hold their color and resist chipping and cracking. Crowns do take longer to prepare than bonding and are not reversible.
What are Dental Bridges?
A dental bridge is a dental appliance that replaces one or more natural missing teeth, thereby “bridging” the space between two teeth. Fixed dental bridges are cemented into place next to “abutment” teeth – the surrounding teeth on either side of the space, or “span.” Unlike removable partial dentures, fixed dental bridges cannot be taken out of the mouth by the patient. A fixed dental bridge is a device that typically consists of three units – a pontic (a false tooth) fused between two crowns that are cemented to abutment teeth.
