Not to long
ago, the only way to significantly alter the shape, color or
size of a tooth was through the use of porcelain fused to
metal crowns. This involved removing tooth structure around
the entire tooth. With the advent of new bonding technology,
thin layers of porcelain can be permanently bonded to the
fronts of teeth. Veneers are another term for these
custom-made shells of porcelain. They're often used to close
spaces and cover badly stained or irregularly shaped teeth.
They provide a much more conservative restoration than the
use of crowns and offer a stronger, more esthetic
alternative to bonding. When to Consider Veneers
Procedure Take the time to explain to your dentist the result you are trying to achieve. Your dentist may take a few x-rays (radiographs) or photos of your mouth; plaster casts may also need to be taken.
The procedure begins with the administration of a local anesthetic; your dentist will remove approximately 0.3 to 0.5mm of enamel from the front surface of all teeth to receive veneers. An impression will be taken and sent to a dental lab where your veneers will be made. At the next appointment, your dentist will fit your new veneers to your teeth. If the fit is satisfactory and you’re pleased with the results, they will be permanently bonded to your teeth, trimmed and polished. They provide one of the most esthetic results cosmetic dentistry can offer. Veneers generally last between 5 to 6 years and require two visits to apply, start to finish.
Advantages & Disadvantages
Porcelain closely mimics the light reflecting properties of natural teeth. In fact, it does this better than just about any other restorative material available. Why Your Dentist May Suggest Against Getting Porcelain Veneers
