In the past, the only way to correct these or other imperfections was to cover the tooth with a crown.
The teeth will need to be reshaped (cut) before veneers are put on. Sometimes, very little reshaping is needed. Other times, more of the tooth needs to be removed.
Veneers look like natural teeth. Porcelain veneers resist stains from coffee, tea or smoking better than resin veneers do. Resin veneers cost less, but they chip easily and don't last as long as ceramic veneers. You and your dentist also should talk about whether veneers will work for you. For some people, the way the teeth come together (the bite) creates pressures that could chip or break veneers.
Next, your dentist will take an impression of your teeth. This will be sent to a dental laboratory. The laboratory will make veneers to fit your teeth. It usually takes 5 to 10 days for the veneers to be made and sent to your dentist. A temporary veneer may be made and put on during this time.
The veneers will be bonded on during the next visit. Your dentist will apply them temporarily first, using water or glycerin. This will allow both of you to see how they look. If the color is not quite right, it can be adjusted. Your dentist may use a specific color bonding agent. Sometimes the veneer will need to be sent back to the laboratory to get the color or shape changed.
Once you're satisfied with the veneers, your dentist will clean your teeth and bond the veneers onto your teeth.
Another type of veneer, which is exceptionally thin (0.2 millimeters), is now available. Use of this type of veneer does not require any tooth preparation. Also, the procedure is reversible because the teeth are not cut.
Doing any of these things can cause the veneers to come off, break or chip. Your dentist may ask you to come back in a few weeks. He or she will check the veneers for any problems.
The veneers may not exactly match the color of your other teeth.
Veneers may fall off. A temporary veneer is more likely to fall off.
