What is a Veneer?
Veneers are thin layers of porcelain or composite material made to fit over a surface of a tooth (usually at the front).
Why would I Need a Veneer?
Veneers are used to improve the colour or shape of teeth, usually at the very front of the mouth. This might be necessary where a tooth is discoloured or chipped or where there are gaps between the teeth (orthodontic treatment to close gaps is very difficult in adults). Veneers are normally recommended for cosmetic reasons but can also be used to reduce wear on teeth. They can produce dramatic improvements in appearance with a minimal amount of preparation. Very little tooth is removed and a tooth can normally be prepared for a veneer without the need for an anesthetic.
What Are the Advantages of Dental Veneers?
Veneers offer the following advantages:
- They provide a natural tooth appearance.
- Gum tissue tolerates porcelain well.
- Porcelain veneers are stain resistant.
- The colour of a porcelain veneer can be selected such that it makes dark teeth appear whiter.
- Veneers offer a conservative approach to changing a tooth's color and shape; veneers generally don't require the extensive shaping prior to the procedure that crowns do, yet offer a stronger, more aesthetic alternative.
What Are the Disadvantages of Dental Veneers?
The downside to dental veneers include:
- The process is not reversible.
- Veneers are more costly than composite resin bonding.
- Veneers are usually not repairable should they chip or crack.
- Because enamel has been removed, your tooth may become more sensitive to hot and cold foods and beverages.
- Veneers may not exactly match the color of your other teeth. Also, the veneer's color cannot be altered once in place. If you plan on whitening your teeth, you need to do so before getting veneers.
- Though not likely, veneers can dislodge and fall off. To minimize the chance of this occurring, do not bite your nails; chew on pencils, ice, or other hard objects; or otherwise put excessive pressure on your teeth.
- Teeth with veneers can still experience decay, possibly necessitating full coverage of the tooth with a crown.Veneers are not a good choice for individuals with unhealthy teeth (for example, those with decay or active gum disease), weakened teeth (as a result of decay, fracture, large dental fillings), or for those who have an inadequate amount of existing enamel on the tooth surface.
- Individuals who clench and grind their teeth are poor candidates for porcelain veneers, as these activities can cause the veneers to crack or chip.
