One of the essential details about veneers that patients need to know is that the porcelain surface is glazed. As long as this glaze is intact, porcelain will retain its resistance to staining. Another aspect of veneers that relates to potential staining is that bonding resin is found at the edge of each porcelain sheath. This is how veneers are affixed to teeth. Bonding resin is not as stain-resistant as porcelain.
Staining around veneers may occur for several reasons. If discoloration occurs only around the edges of veneers, it may be possible to resolve the problem by visiting an experienced cosmetic dentist for an evaluation. Standard stains that have developed in bonding resin may disappear when veneers are polished in the dental office. Another reason for outer-edge discoloration is that a microscopic gap has formed between the tooth and the veneer. This is referred to as micro-leakage.
Depending on the extent of separation between a veneer and natural tooth structure, micro-leakage may be repaired using an etching technique. However, if veneers are quite old, separation may have resulted from deterioration of the bonding material around porcelain material. If necessary, your dentist may recommend veneer replacement.
Porcelain veneers are durable and can last upwards of twenty years. However, the edges where veneers are bonded to enamel are vulnerable. This is because bonding resin, which is sandwiched between enamel and porcelain, is softer than those two materials. Knowing this, you can support long-term results by:
