The durability of veneers depends on the material they are made from and on the condition of the teeth they are placed on.
Resin veneers are made from a plastic-like material (composite resin). They last up to five years, are more prone to staining and chipping. They require regular polishing and maintenance to keep their lustre.
Ceramic veneers made from specialised dental porcelain can last up to 15 years. They do not stain easily but can chip or fracture if excessive forces are applied to them. While less maintenance is needed for ceramic veneers to keep their lustre, chipping or fracturing is harder to repair and might require a full replacement.
The condition of the teeth on which the veneers are placed will affect the veneers' lifespan. Teeth need to be free of decay and gum disease before veneers are placed. Decay in the teeth can lead discoloration of the venner or to the veneer falling off prematurely. Gum disease can lead to the teeth becoming loose and falling out.
Before veneers are placed, it is essential that a full oral assessment is made to ensure teeth are free of decay and gums are healthy.
Good oral hygiene and regular professional cleans are also critical to maintain the lifespan of veneers.
