Crowns are necessary when a tooth is broken down. Crowns are also used when there isn't enough of the tooth remaining to provide support for a filling. If a tooth is cracked, a crown holds the tooth together so the damage doesn't get worse. Crowns may also cover badly shaped or discolored teeth and go on top of dental implants.Remember to ask us about our CEREC one day crowns!Bridges are natural-looking restorations that use either teeth or implants to replace a tooth or a section of missing teeth. To do a bridge, the dentist takes teeth next to the missing space and shapes them so they can receive crowns that will hold the missing tooth or teeth. Because they are custom-made, bridges are very esthetic and can restore the natural contour of teeth as well as the proper bite relationship between. Bridges are bonded into place with high-tech adhesives.
