They can both give you really good results however composite veneers will require some artistry of the dentist to layer and characterize the color match or to create shape and contour of the teeth, whereas the porcelain veneers are made by a ceramist. Both of them are great options. However the composite restorations will stain over time, they will absorb some of the astringent stain in the mouth from coffee or tea or various beverages. The strength of that material, since it's a plastic base material, is not as strong as porcelain. So I would say a longevity expectations, the color stability and the strength make the composite a little less of a product than the porcelain.
Q: Composite veneers and porcelain veneers seem like they yield the same results, what are the differences?
What our experts say:
Composite veneers and porcelain veneers initially can look very similar. However, they are two very different materials. Bonding veneers are made of a plastic based material and porcelain veneers are actually porcelain. The differences lie in the long-term color stability and wear. So bonding, over time, will stain, yellow, wear down and thin out. Porcelain veneers do not wear and do not stain.
