Can I get cavities with Lumineers?

Sunday, May 23rd, 2010

Once you have placed something like Lumineers over your teeth, what happens to the ongoing health of the underlying teeth? Can you still get cavities, etc.? Will your regular dentist be able to spot the cavities and repair them as easily as before Lumineers? What will filling cavities do to the veneers? What will brushing and flossing do the veneers? Also, is it possible for the veneers to lose their color just like natural teeth? Thanks for your insight!

David,
Yes, once you have Lumineers, or any brand of porcelain veneers, it is possible to get cavities in those teeth. You won’t get a cavity under the veneer, but you could get it on the edge or another place on your tooth. This cavity can be filled with white filling materials, and it’s not too different from any other cavity on a front tooth, except that special bonding techniques are needed to bond the filling material to the porcelain. So it’s good to have your artistic, specially trained cosmetic dentist do the filling – just as you would have this special dentist do the original smile makeover.

Having said that, as a cosmetic dentist, I discourage people who tend to not take care of their teeth from getting porcelain veneers. After investing so much money in a beautiful smile, if you then get a lot of cavities on those teeth, it can really affect the longevity of the veneers, and they could end up needing to be replaced with crowns. My advice is that, if you get a smile makeover, take good care of it by brushing and flossing every day, getting regular checkups, and don’t be a constant snacker. The snacking habit leads to lots of cavities.

What if I have cavities on my front teeth and want porcelain veneers?

Saturday, January 23rd, 2010

I have some cavities on my front teeth near the gum line. Would I need to get those taken care of before I get veneers? Also, I have a tooth where the filling came out, again, is that something that I would need to fix before getting veneers? What kind of dental problems other than whitening or staightening do they solve?

Debi,
Any cavities defective fillings you have on your front teeth should be taken care of before getting porcelain veneers. And the porcelain veneers can simply be placed over those fillings.

And yes, porcelain veneers can make your teeth whiter, can make crooked teeth appear straight, can make your teeth longer or shorter or more squared or more oval, or whatever you want. They are simply a way to get your teeth to be whatever color or shape you want them to be.

Can I get a porcelain veneer over my crown?

Thursday, July 9th, 2009

I have a porcelain crown on my front tooth that I have had since I was 13. It still looks good but has a small crack in it.  Could I have a porcelain veneer put over the top of this instead of getting a new crown made? I just am worried that the crown is going to break. – Georgia from Oregon

Georgia,
Yes, you can get a porcelain veneer put on top of a porcelain crown. But what you really need is a new crown. And there are two excellent reasons.

The first is that if the underlying crown is cracked, then the porcelain veneer that is bonded on top of it will probably crack, too. Porcelain veneers by themselves aren’t very strong – they derive their strength from the underlying tooth and from being bonded to the tooth. Bonded on top of cracked porcelain will make it likely crack.

The second reason is that at most dentists it costs pretty much the same to get a porcelain veneer as it does to get a porcelain crown. It’s about the same amount of work, and the laboratory fee is usually the same. And a new porcelain crown will last much longer than your patched crown. So why patch the crown, pay the full price, and then in two or three years need a new crown anyway? That’s unnecessary expense.

I might add that if the crack in your porcelain crown isn’t noticeable, it could be just a craze line and the crown could last for quite a bit longer. If it’s a crack that goes all the way through, then the crown would probably need to be replaced. But if it’s just a superficial craze line, it may not need to be.
