In dentistry Veneer is a thin layer of material placed over a front tooth to:
a) Improve the aesthetic of a tooth (color, shape, size)
b) Protect the tooth’s surface from damage or worn out as people age
c) Restore a broken tooth
d) Close small gaps
1) Porcelain Veneers
Is a less invasive method than the crowns. The dentist has to remove only half to one millimeter of the outer layer of the enamel only on the front side of the tooth. A local anesthetic may be used to make sure there is no discomfort. After the impression is taken is send the technicians laboratory along with all the necessary information (color, shape, size). A few days later the veneers are ready to fit in place. They are bonded with a special light-sensitive resin glue.
Sensitivity to hot and cold temperatures due to the removal of that thin layer of enamel or the chemical glue may occur. This typically disappears within a few days.
Porcelain veneers must be treated as your own teeth with daily brushing and flossing. Although they are very strong, veneers are also brittle. You should avoid excessive stress as you would with your original teeth. Don’t bite your fingernails, chew ice or open bottles!
If you have the habit of grinding and clenching your teeth your dentist may fit you with a night-time bite guard so you don’t damage your veneers.
Nowadays the new materials of monolithic zirconio in combination with adavanced technology of Computer Aided Design and C0mputer Aided Mashining CAD/CAM offer excellent results which you can hardly distinguish from the natural teeth. CAD/CAM technonogy can provide us with very thin porcelein facings which means very little to no preparation of the tooth.
2) Componeers – A Smile to go
Componeers are polymerized, prefabricated, composite enamel shells, thin as a contact lens. It’s a new, easy-to-use system for restoring anterior teeth .They combine the advantages of laboratory veneers and direct composites offering dentists and patients a new economic perspective in just one session.
