Veneers are very thin shells that are applied to the entire front part of the teeth to help improve the cosmetic appearance of teeth by changing their colour, shape, angle or spacing. Veneers generally come in two different materials: composite resin or porcelain. They both serve the same purpose with the primary difference being that porcelain veneers while more expensive, are more durable and more resistant to staining.
For composite resin veneers, the process is much like bonding. The dentist applies a mild chemical to the front of your teeth to roughen the surface to allow for better adhesion. After this, the dentist will apply the composite resin and shape each tooth, hardening it with a strong curing light between each layer. Composite resin veneers can usually be done in one visit.
For porcelain veneers the process is slightly different. A mold is taken of your teeth so that the porcelain veneers can be custom made. Because of this, porcelain veneers usually take two visits to apply. On your second visit, the process is much like bonding where the dentist will first apply a mild chemical to the front of your teeth to roughen the surface and allow for adhesion, and then one by one apply each veneer with a bonding agent.
Veneers also need the same care as your natural teeth, so a proper oral health care routine that involves brushing and flossing your teeth is critical for their care. Avoiding chewing on hard objects that may cause damage such as ice can also go a long way in prolonging the life of the veneers.
