Can a veneer that fell off be bonded back on?
Often yes — if the shell is intact and the tooth underneath is sound.
Whether a detached veneer can be reused depends on how it came off. A clean separation at the cement layer is a very different situation from a shell that cracked as it detached.
When rebonding works — and when it does not
If the porcelain is whole and the tooth shows no decay, the dentist can clean off the old cement, re-treat both surfaces, and bond the same shell back with results close to the original. The shell must seat exactly, which is why professional bonding — not home adhesive — is required.
A cracked or chipped shell, decay under the veneer, or repeated debonding usually points to a new restoration instead. Outcomes differ case by case, so bring the shell to your dentist and have the tooth examined before deciding.
