The process of getting porcelain veneers usually takes two to four visits to the dentist over the span of a few weeks. The first one or two visits involve the consultation and preparation of the teeth, which can take several hours. The third visit is when the veneers are placed on the teeth, which can take around one to two hours. In some cases, a fourth visit may be necessary for final adjustments or refinements to the veneers. Overall, the entire process can typically take anywhere from two to four weeks, depending on the individual case and the dentist’s schedule.
