Dental crowns, also known as "caps," preserve the functionality of damaged teeth. A dental crown may be used to protect a cracked tooth, restore functionality of a tooth with excessive decay or replace a pre-existing crown. The purpose of a dental crown is to encase a needy tooth with a custom-designed material.
Once you and your dentist determine that a dental bridge is the best replacement for your missing tooth or teeth, you will be advised of different materials that the dental laboratory can use to make your restoration. Dental bridges today can be fabricated from a combination of porcelain and metal, porcelain and other high-strength materials. Your dentist will take X-rays and impressions of the area requiring a bridge, as well as preoperative photographs, for use in planning the ideal bridge restoration for you. Depending upon the number of consecutive teeth you are missing, your bridge could be three or more units; two crowns that are cemented to the teeth on either side of the space (called abutments), plus one or more false teeth (called Pontics) to fill the space. Additional impressions will be taken after your dentist prepares the abutment teeth for the bridge.
