A dental crown is a tooth-shaped “cap” that is placed over a tooth - covering the tooth to restore its shape and size, strength, and/or to improve its appearance. The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line.
Dental bridges literally bridge the gap created by one or more missing teeth. Since the gap left by a missing tooth can cause the remaining teeth to shift or move, it is important for your oral health to replace the missing tooth or teeth, and fixed bridges are one of the solutions for doing so. A bridge is made up of two crowns for the teeth on either side of the gap – these two anchoring teeth are called abutment teeth – and a false tooth/teeth in between. These false teeth are called pontics and can be made from gold, alloys, porcelain or a combination of these materials. Dental bridges are supported by natural teeth or implants.
