Can you put porcelain veneers over teeth with resin?

Ideally the margins of the porcelain veneers (the edges, or the interface from porcelain to tooth) are on enamel, but with the right bonding agents even a resin margin will work just fine. It is common to use resin underneath a veneer to block out colors so that the veneers will appear the desired color.While we only want to remove the least amount of enamel necessary, most cases will require SOME enamel removal.  It is possible that while YOU feel the enamel removal was extreme, a trained cosmetic dentist would state it was a normal amount that was removed.

Porcelain veneers can be bonded to dentin and to composite resin! However if the enamel is removed, and you have only dentin, the bond is not as strong!It does not matter that your dentist placed composite resin first, to dentin, and now we bond the veneer to composite! the fact remains that the bond is not as strong as to enamel! At least the expert dentist will think about retention form and manage the bite, so no excessive force will be exerted to the compromised bonded veneer!

HI:Good question.  Yes, porcelain veneer can be bonded over veneers with out any trouble.Best,Dr. Maddahi
