CROWNS AND BRIDGES
A dental crown is a tooth-shaped "cap" that is placed over a shaved or reduced tooth, it cover the tooth to restore its shape and size, strength, and improve its appearance. The crowns are cemented into place with specialized cements and fully encase the entire visible portion of a tooth that lies at and above the gum line.
Bridges are commonly used to replace one or more missing teeth. They span the space where the teeth are missing. Bridges are cemented to the natural teeth or implants surrounding the empty space. These teeth, called abutments, serve as anchors for the bridge. A replacement tooth, called a pontic, is attached to the crowns that cover the abutments.
As with crowns, you have a choice of materials for bridges. Your dentist can help you decide which to use, based on the location of the missing tooth (or teeth), its function, aesthetic considerations and cost. Porcelain or ceramic bridges can be matched to the color of your natural teeth.
Dental veneers (sometimes called porcelain veneers or dental porcelain laminates) are thin, custom-made shells of tooth-colored materials designed to cover the front surface of teeth to improve your appearance. These shells are bonded to the front of the teeth changing their color, shape, size, or length.
They require minimal or no reduction of the enamel of the tooth making it a very conservative approach when restoring the appearance of your teeth.
