Can porcelain veneers be repaired? i have a porcelain veneer on one of my front teeth that looks like it has a crack in it. is this something that can be repaired, or will i have to get it replaced entirely?

Most : Most likely it will need to be replaced to give the best and most aesthetically pleasing result. However, the cause of the crack needs to be determined to prevent the same situation from happening again. Have you ever noticed a crack in the drywall in your home? You could try to spackle over it, sand and repaint, only to see the crack come back.

Small : Small 'chips' in a porcelain veneer can be repaired with composite or 'bonding' material....However, the color match may not be good between the porcelain and composite material. If a large piece of a veneer has broken off, or the gumline has risen, exposing the root, a new veneer should be done.

Porcelain : Porcelain veneers cannot be repaired, once cracked or fractured it will always be noticeable. I therefore recommend to you have your veneer replaced. Good luck!

Porcelain : Porcelain veneers are bonded wholly to the tooth. It is possible that a cracked veneer may never come off because each portion is equally bonded to the tooth. As long as it is not an esthetic problem, and as long as the crack is not so large that it allows leakage to the tooth, you may be able to maintain that veneer for a long time. However, if you are concerned about it coming off, or any of the other possibilities- get it replaced.

Replaced: Any attempt to repair a porcelain veneer will ultimately fail, even small chips the have composite bodied in place. It never lasts. If you simply see cracks, but nothing is broken or missing, it may last for quite some time, assuming they were bonded in place correctly. Much of the material strength comes from being bonded (consider ceramic floor tiles. Very strong once glued to the floor).

Yes but...: Repairs can buy some time; however, they are rarely long-lasting. If you want a long-term result i would seriously consider remaking the veneer. I would also make sure you are wearing a night guard to protect the veneers as you sleep.

Yes/no: Yes they can be repaired but repairs in porcelain veneer (even crowns) do not have a great long term prognosis. I only do it as an emergency treatment but they will eventually fail. I would have it replaced
