There are two main types of dental veneers.
Composite dental veneers:
These are made by placing layers of composite resins on the tooth that are hardened by polymerisation using ultraviolet light. They are then given the desired shape and colour shade to match the rest of the teeth. This is where the artist’s part of the professional and his or her experience comes in.
Composite veneers require little or no grinding of the tooth. The procedure can be done in a single visit and is painless. In addition, composite veneers are easy to repair in case of fractures and are the most economical option.
Ceramic dental veneers:
These are thin sheets of ceramic material (feldspar) that give very good aesthetic results. This material is more resistant than composite veneers, both to breakage and wear, but in the event of fracture they must be replaced. They are made to measure in specialised laboratories and using a model of the teeth taken by the professional in the clinic.
They are then placed on the prepared tooth using a powerful adhesive. The placement of ceramic veneers requires a small amount of grinding of the tooth, depending on the thickness of the ceramic layer, and several visits are needed to place them.
