Veneers are made out of porcelain and are fabricated to correct slightly misaligned teeth or to cover discolored teeth that will not bleach.
Ceramic laminate veneers are all white, thin ceramic shells, which fit precisely onto the faces of prepared anterior teeth. Like bonding, veneers are used to cover up discoloration, cracks and chipping. Dental veneers can also be used to change the shape and size of your teeth. Veneers outperform bonding with greater resilience and a greater resistance to stains and dulling over time.
Most veneer procedures require two appointments to complete, the first of which is dedicated to preparing and taking an impression of the teeth. Veneers are minimally invasive restorations. Therefore, we need to remove only a small portion of the face and top edge of a tooth to achieve a proper preparation design. After the tooth or teeth are prepared, an impression is taken, which, along with accompanying photos and models, is sent to the dental laboratory. The dental technician fabricates porcelain shells that will fit precisely on your teeth.
During your second appointment, veneers will be permanently cemented to your teeth. Be sure to leave plenty of time for this appointment, since placing veneers is a meticulous and delicate procedure. Each veneer must be trial fitted and assessed for aesthetic and functional success before final cementation. If necessary, fine adjustments are made prior to or immediately after final cementation.
Ceramic laminate veneer procedures are exacting, but the results can be extremely rewarding. Stronger and longer lasting than composite resin restorations, they are the current state-of-the-art procedure to restore and enhance your smile.
More Details About Porcelain Veneers
What are porcelain veneers?
Porcelain veneers are ultra-thin shells of ceramic material, which are bonded to the front of teeth. This procedure requires little or no anesthesia, and can be the ideal choice for improving the appearance of the front teeth. Porcelain veneers are placed to mask discolorations, to brighten teeth, and to improve a smile. Highly resistant to permanent staining from coffee, tea, or even cigarette smoking, the wafer-thin porcelain veneers can achieve a tenacious bond to the tooth, resulting in an esthetically pleasing natural appearance that is unsurpassed by other restorative options.
Why restore your teeth with porcelain veneers?
Porcelain veneers are an excellent alternative to crowns in certain situations. They provide a much more conservative approach to changing a tooth’s color, size, or shape. Porcelain veneers can mask undesirable defects, such as tetracycline stained teeth, teeth discolored by injury, or as a result of a root-canal procedure. Veneers are also great at masking discolored fillings in front teeth. Patients with gaps between their front teeth or teeth that are chipped or worn may consider porcelain veneers.
Preparation of teeth for veneers
The patient should spend time in the evaluating, decision-making, and planning of the smile and understand the corrective limitations of the procedure.
To prepare the teeth for the porcelain veneers, the teeth are lightly shaved down to make room for the thin piece of porcelain. Usually, about a half a millimeter or less of the tooth is removed, which may or may not require local anesthesia. At this appointment, a mould of the teeth is also obtained and sent to the laboratory for the fabrication of the veneers. The fabrication process can take about a week. Depending on the amount of reduction and appearance of the prepared teeth, if needed, temporary veneers can be fabricated.
Bonding of veneers
Before the veneers can be permanently cemented they need to be tried in. First, the dentist places the veneers on the teeth with try-in paste. Through this process the fit and shade of the veneer can be evaluated. While the veneers are resting on the teeth, the esthetic appearance of your smile is examined with attention being placed to the shape, shade, and overall appearance of all the teeth. At this point, the color of the veneers can still be modified with the shade of the cement to be used. The color cannot be altered after veneers are permanently cemented. For proper bond to occur between the veneer and tooth, the tooth is cleansed and prepared with specific chemicals. Once a special cement is sandwiched between the veneer and tooth, a light beam initiates the release of a catalyst that hardens the cement.
For about a week or two, the patient will go through a period of adjustment as he/she gets used to the “new” teeth that have been changed in size and shape. Regular brushing and flossing should be performed to maintain the health of the gums.
Have realistic expectations
Porcelain veneers are reasonable facsimiles of natural teeth, not perfect replacements. Upon close inspection it is common to see slight variations in the color of the veneers. This is what gives the veneers their natural appearance. Similarly, our teeth exhibit natural color variation which makes them appear real and natural. Nevertheless, porcelain veneers can greatly enhance a smile, and can heighten inner satisfaction and self-esteem.
