Porcelain veneers are thin layers of porcelain placed over an existing tooth. Sometimes these veneers are placed over teeth that have been damaged and sometimes the placement of veneers is purely aesthetic.
There are two basic ways that these veneers are placed over the teeth. They can be built in the mouth by applying thin layers of the composite material until there is adequate coverage, or the veneer can be fashioned in a lab by a dental technician and then placed over the tooth. When creating porcelain veneers the only acceptable method is to have a dental technician construct them in a laboratory.
When veneers were first invented by Charles Pincus they were unreliable. The first ones were placed over teeth and held in position using dental adhesive. The adhesive would not hold them in place for very long. The majority of veneers that were made in those early days were made to place in the mouths of actors so they could change their appearances.
In 1982, research began to prove that porcelain veneers could be etched with hydrofluoric acid causing them to be able to be bonded to the natural tooth surface. This research would prove that these coverings could be made to stay on the teeth for many years before they needed to be reattached. This increased the number of the porcelain veneers that were used.
Since that time the bonding agents have been greatly improved and these veneers are expected to stay on for no less than ten years and no longer than about thirty years. After thirty years, the veneers have a tendency to chip or become the ill-fitting and allow food particles to get to the natural tooth beneath them.
The price that you pay for these items will depend on the portion of the United States you live in. Dental procedures in the mid-west are less expensive than dental procedures on either of the coasts are. The experience of the dental professional you hire to do the work will also reflect on the price you have to pay.
There are actually do it yourself kits available so people can take molds of their teeth and have veneers made to cover them. The non-permanent veneers are made in a lab by a dental technician and then shipped to the customer’s home where they place them over their own teeth. These items do not stay in position as long as the ones the dentist places over the teeth do.
The do it yourself veneers are not porcelain veneers. They are made of a flexible resin that can be removed and replaced several times before they need to be thrown away.
Most dentists will try and discourage their patients from getting these items for minor cosmetic reasons. The drawbacks to covering your natural teeth with them are too great to take the risks unless it is necessary that you do. As much as thirty percent of the tooth surface is destroyed in the preparation of placing the veneers on them.
Porcelain veneers can cover teeth that have been damaged or that are aesthetically unsightly. Porcelain veneers are expected to last between ten and thirty years before they need to be replaced.
