Porcelain veneers are often used in cosmetic dentistry to change the colour, size. Shape and length of your teeth, improving the overall appearance. They are a thin shell (thickness of a fingernail) of tooth coloured material bonded to the front surfaces of your teeth.
Veneers can be made of porcelain or composite resin. While composite resin is more affordable the advantage of using porcelain lies in the fact that it is stronger, more resistant to stains and cam mimic the life-like appearance of tooth enamel.
Before veneers can be considered, consult your dentist as active gum disease, decay, certain genetic conditions resulting in insufficient enamel are contra indicators. Also if you grind or clench your teeth, porcelain veneers may not be suitable, as these habits can lead to chipping, cracking or loss of veneers.
To prepare your teeth for porcelain veneers, the dentist will trim around ½ mm of enamel from the existing tooth surface. Usually this can be done without local anaesthetic. Then an impression of the tooth is take and send to a dental laboratory where your veneers will be constructed. This usually takes two weeks. At the next appointment, the veneers are tried for colour and fit. Then they will be boned to teeth with a special adhesive that’s set by light. Your bite will then be checked and any adjustment to the veneer will be done. Veneers, as any other medical procedure, have risks associated. Firstly, some tooth enamel is removed to prepare for veneers, this may lead to sensitivity. Secondly, veneers are a thin layer of material bonded to teeth, they can chip, break or debond, and may need to be recemented or replaced.
