Crown

A dental crown is a tooth-shaped “cap” that is placed over a tooth  to cover the tooth to restore its shape and size, strength, and 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. Permanent crowns can be made from stainless steel, all metal (such as gold or another alloy), porcelain-fused-to-metal, all resin, all ceramic/ porcelain or zirconium.

Bridge

A bridge is made up of two crowns one on each tooth 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, zirconium, porcelain or a combination of these materials. Dental bridges are supported by either natural teeth or dental implants.
