The benefits of composites definitely begins at the price point, and you can see below just how drastic a price difference there is between the two. As well, a composite veneer can be applied within one dental visit. The most notable benefit of a composite is that it can be repaired if damaged. The downside of this type of veneers is they generally will not look as natural or appealing as their porcelain counterpart, and they certainly do not last as long. They will discolor over time, and they do tend to chip and crack. As well, while you can normally expect a composite veneer completed in one dental visit, the "in chair" time is around 2 to 3 hours, depending on the amount of work required. This can be a hassle for those dental appointments that normally take place during a work day.
