Porcelain veneers are excellent for restoring otherwise sound teeth that are stained, chipped or slightly misaligned. But the question for many is, are they long-lasting?Just as the term is used in building construction, a dental veneer is a thin covering of material that’s bonded to the outside of a tooth to conceal blemishes. Very thin layers of dental porcelain (a form of hardened glass colored to match a patient’s natural teeth) are created by a dental lab technician to achieve the preferred shape and size of the patient’s tooth. Unlike crowns or other restorations, veneers require very little tooth preparation to accommodate them.As to their longevity: if cared for properly, a veneer could last for twenty years or more. While the veneer itself isn’t subject to the effects of dental disease, the tooth and the gums that support it are. Shrinking gum tissues as a result of periodontal (gum) disease, for example, could have a negative effect on the veneered tooth and subsequently the veneer. It’s important, then, that you properly practice daily brushing and flossing, along with keeping up regular office cleanings and checkups.There’s one other important consideration: while porcelain veneers can withstand normal biting forces, if they’re subjected beyond their tolerance they could shatter. You should be careful not to subject your veneered teeth to an abnormal biting force, such as biting down on an extremely hard object. If you tend to grind your teeth at night, wearing a night guard can minimize the force created from the grinding.It’s possible to repair and re-bond a loose or slightly chipped veneer. In some cases, though, severe damage may require a replacement. Still, by using common sense about what you bite down on and taking proper care of your teeth and gums, you can minimize the chances of damage and enjoy many years of a more attractive smile.If you would like more information on porcelain veneers, please contact us or schedule an appointment for a consultation.
