Crowns and Veneers
Veneers are thin, custom-made shells crafted with tooth-coloured materials that cover the front of teeth. Veneers can improve the appearance of teeth by changing their shape and colour, masking stains and replacing fractured pieces of teeth. They can also artificially make teeth appear straighter. Veneers are usually made from porcelain which keeps its appearance far longer than tooth coloured resins that wear away more quickly. Porcelain can be brittle however and chip. If you have porcelain veneers, the ADA recommends ditching habits like biting fingernails, chewing pens/pencils, and taking care when biting into stone fruits or using teeth to open packets (which should really be avoided regardless of veneers or not).
Dental crowns cover or encase the tooth on which they are cemented. Dentists use crowns when rebuilding broken or decayed teeth to strengthen teeth, and as a method to improve appearance. Crowns are made in a dental laboratory by a dental technician who uses moulds of your teeth made by your dentist.
The type of crown your dentist recommends will depend on the tooth involved and sometimes on your preference. They include porcelain crowns, porcelain-bonded-to-metal crowns, which combine the appearance of tooth coloured material with the strength of metal, gold alloy crowns and acrylic crowns.
