Although the costlier option, porcelain veneers are more lifelike, aesthetically pleasing and robust as compared to their composite resin counterparts.
Since porcelain veneers are usually fabricated at a dental laboratory, the veneering process requires a few visits to the dentist, whereas a composite restoration can be applied in one sitting.
During the initial visit, the dentist will remove an ultra-thin layer of enamel from the front and sides of the patient's teeth, to create a sliver of room in which to accommodate the incoming prosthetic. The dentist will then create an impression of the prepared teeth to serve as a blueprint of the prepared teeth site. The porcelain shells will be fabricated, typically at a dental laboratory, based on the dimensions, size and shape of the impression.
Once the veneers are ready, the patient will be asked to return to the dentist’s office for final adjustments and fitting of the porcelain veneers. The dentist will first place the porcelain veneers over the prepared teeth to ensure that they conform to size and shape. Following some minor adjustments, where necessary, the tooth shells are bonded to the teeth using dental cements. The dentist may arrange for follow-up visits to make sure everything is in order, and determine whether further modifications or adjustments are required for a perfect fit.
