There are many reasons to consider porcelain veneers. Tooth enamel may have become discolored by the effects of smoking, coffee, or age. Teeth may also become discolored by certain drugs, excessive fluoride, or as a result of a root canal. Veneers are often used to correct the look of teeth that are misaligned or have gaps between them. Teeth that have been broken or have been damaged by tooth grinding may also be repaired using veneers.

Porcelain veneers are ultra thin shells placed over the existing teeth. The two types of material used for these veneers are dental porcelain and resin composite. Porcelain veneers are much more stain resistant, more durable, and more closely match the look of natural teeth. Resin composites are less expensive and they are thinner, requiring less removal of the natural tooth surface. The resin composite (“bonding”) material will become stained and discolored over time as opposed to porcelain veneers which are stain resistant. Both are bonded to the existing teeth using a special light activated bonding compound. 

Since veneers are a financial investment, the first step is usually a consultation with a qualified dentist to determine if veneers are the best option for the individual situation. It is also important to consider the fact that veneers are an irreversible treatment. Adjustments can be made and the veneers can be replaced, but since a thin layer of the original tooth’s enamel must be ground off in order to adhere the veneer, the process cannot be reversed.

There are some veneer products that do not require grinding and these ultra thin veneers are bonded directly to the cleaned and prepped teeth. These are more controversial than standard veneers and some dentists do not recommend this application since a thinner material may not hide the problems it was designed to cover as completely as a thicker shell. Another issue with these types of veneers is that although they are thinner than traditional veneers, they still add bulk to the surface of the tooth and they can create a tiny ridge where the veneer stops. This area may collect stains or plaque and may cause irritation at the gum line.

At the first visit, the dentist will explain the procedure and may take x-rays or do an impression of the mouth and teeth, depending on what the veneers are being used to correct. The order is then sent to a lab and usually is completed within three weeks depending on the situation. To apply the veneers, the teeth are cleaned, polished and then etched or roughed in order to provide optimal adhesion for the bonding compound. Once the veneer is in place a special light is used to activate the bonding resin causing it to cure very quickly. The veneers are then checked again, for proper placement and any excess bonding cement is removed.

With proper care and maintenance, veneers may be expected to last anywhere from 10 to 20 years depending on the type of material used. They should be cared for in the same way as natural teeth so it is important to maintain good oral hygiene and continue to see a dentist regularly.
