Dental veneers (sometimes called porcelain veneers or dental porcelain laminates) are wafer-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.

Dental veneers can be made from porcelain or from resin composite materials. Porcelain veneers resist stains better than resin veneers and better mimic the light reflecting properties of natural teeth. Resin veneers are thinner and require removal of less of the tooth surface before placement. You will need to discuss the best choice of veneer material for you with your dentist.

Facts about Veneers & Laminates :

  • Occasionally, the preparation of a porcelain laminate veneer does not necessitate the use of a local anesthetic. However, for those patients that are particularly sensitive or anxious, a local anesthetic is advisable.
  • The laboratory time required for the fabrication of a porcelain laminate veneer is approximately one week, although this may vary.
  • You can expect some sensitivity to hot and cold. This is normal and is due to the removal of a small portion of the tooth’s enamel covering. This sensitivity should disappear a few days after the placement of the veneers.
  • The insertion or cementation of your laminate veneers can be accomplished once again with or without local anesthetic. This visit is usually longer in length. The laminates are placed with a light-sensitive resin hardened with the use of a white light, effectively bonding them to your teeth.
  • Once placed, your laminate veneers are very strong and will resist most of the forces placed upon them by a normal diet. Porcelain is a glass and like glass it is strong, but brittle. Therefore, you should avoid anything that will tend to stress the laminate veneer.
