Porcelain veneers or dental veneers are thin layers of porcelain that are placed over the front part of the tooth to improve its aesthetic or protect it. The process of placing veneers takes at least two visits to the dentist. During the first visit the tooth is prepared and the shade of the tooth is matched with the veneers. In the second visit the veneer is fixed to the tooth. The procedure might require very little or no anesthesia at all because it is only a thin layer of the enamel that is scraped off from the tooth and nothing else.
Maintaining porcelain veneers is not any different from maintaining normal teeth; it includes routine brushing and flossing. You should go to the dentist for polishing and checkup so that they can check for any potential failure. Polishing should be done with a special non-abrasive paste. You should also avoid grinding or clenching your teeth as this habit damages the veneers.
