The integrity of veneered teeth is only marginally compromised, and the veneer is bonded to the existing teeth. There is no higher incidence of decay provided the veneers are properly cared for as previously mentioned with regular flossing and brushing with toothpaste. In general, it is good dental advice to keep your sugar consumption low and confined to meal times to prevent decay.

They can last from seven to twenty years. While the veneer itself is inert and non-living, the tooth or teeth to which they are attached and the surrounding gum tissues are living and may change. For example, gum line shrinkage may expose or reveal root surfaces. If a veneer comes off it can generally be rebonded. If it chips it can sometimes be re-bonded or otherwise replaced.

Because some tooth structure and enamel are removed prior to placing veneers, this is considered an irreversible treatment. Veneers may be replaced, but removing them for good will leave your teeth permanently scarred, at high risk for damage, and unhealthy looking.
