Question: Can a chipped veneer be repaired?
Explanation: A chipped veneer means a piece of porcelain has fractured away while the remainder stays bonded. Small chips at the incisal edge can sometimes be polished smooth or repaired with composite bonding, though colour matching to porcelain is difficult and the repair is less durable. Larger chips generally require replacing the veneer. The critical step is establishing why it chipped. Grinding, an interfering bite, or biting nails or thread are common causes. Repairing without addressing the cause simply postpones the next fracture.

Does composite bonding to porcelain last?
Less well than bonding to enamel. The porcelain must be etched with hydrofluoric acid and treated with a silane coupling agent. Even then, the repair typically survives a few years rather than a decade. It is a reasonable interim measure but rarely a definitive one.
Will a repaired chip match the rest of the veneer?
Approximately, rarely perfectly. Porcelain has a translucency and light-scattering quality that composite resin does not fully replicate. In a front tooth visible when smiling, a discerning patient often notices the difference over time as the composite picks up stain.
How can I stop my veneers chipping again?
Wear a night guard if you grind. Have the bite checked and adjusted so no single veneer takes excessive load. Avoid biting nails, pens, thread, and hard foods with the front teeth. Veneers are for appearance, not for tearing open packaging.
