Veneers set not only for cosmetic purposes.veneer technology allows the creation of a crown to make, if necessary, the pin tooth or a small bridge.
whole process of settling down veneers takes about a week.Dentist to visit twice: first for the treatment of teeth and remove the impression, then - for the actual installation.
first stage - this special treatment of the tooth, which will set the veneer.To do this, from the front surface of the tooth is removed a thin layer of enamel, equal to the thickness of the intended veneers.This procedure does not hurt and does not weaken the tooth.If your teeth are sensitive slishom, during their processing can be used local anesthesia.After the treatment, the dentist removes the tooth impression (mold), in which the laboratory will make your future veneer.
Sometimes veneers are made right in the dentist's office - then the whole procedure is placed in one visit.With the help of high technology, you can get the "optical impression" of a tooth on a special machine, which immediately generates a veneer on the model.Some dentists believe that high-quality veneers can be made by hand, in a special laboratory, and the car copes with the problem worse.
The laboratory veneers are made about a week.Sometimes during this period on the tooth put temporary veneers to the patient is not experiencing discomfort from rough teeth.True, temporary veneers has a drawback - they are easy to slip off or break a tooth so that you can endure without them.In each case, this is solved individually.If you decide to dispense with temporary veneers, avoid hot and cold - a tooth after removal of the surface layer becomes very sensitive.

Immediately before installing the first applied to a tooth gel, which increases the strength of adhesion to the tooth surface of the veneer.Thereafter, the cement is applied to the veneer and the veneer is attached to the tooth.Then, under the influence of a special light source cement hardens within a few seconds due to its photosensitive catalyst composition.After the final installation of the dentist, like the artist, brings a "picture" of the finishing touches - smoothes the contours, making allowance for the bite.The installation of the veneer is completed.
Porcelain veneers compared to other methods of aesthetic dentistry have several advantages.First of all, they give the tooth a natural healthy look.Used in their manufacture dental porcelain closely mimics the properties of the surface layer of the tooth - enamel.In addition to porcelain veneers does not appear stains, discoloration or turbidity.This smooth and impermeable material is not afraid of red wine, tobacco, coffee and tea.
