Bonding vs Porcelain Veneers

Tuesday, January 27th, 2009

Hello, I had my 8 front upper teeth fully bonded about 14 years ago to close in gaps between them. I have taken extremely good care of them and they have held up well, although they have stained now from food and drink. I have been told my only option for white teeth is to remove the bonding altogether,then bleach and rebond or go the more expensive route, porcelain veneers. My question for you is this… if the tooth is actually what has become stained and it is showing through the bonding, why wouldn’t bleaching work? If the coffee, tea, etc. got through, wouldn’t they bleach also?? Thank you.

Dear Patti,
I think you’re being given good information.

I’m not clear whether you want your teeth generally whiter or you want the stains removed. If you just want the stains removed, the bonding could maybe be re-surfaced. The cosmetic dentist would just remove enough of the surface of the bonding to get rid of the stain, and then bond new material over that. But if you want your teeth whiter than they are, too, then you need to remove the bonding, have the teeth bleached, wait a couple of weeks for the new color to stabilize, and then re-bond.

We do a lot of direct dental bonding, and the bonding material can produce beautiful results. But the bonding resin is a little bit porous, and over the years it will absorb stain. This stain doesn’t respond to any of today’s bleaching techniques, even the state-of-the-art Zoom whitening that we offer.

If you were my patient, I would encourage you to upgrade to the porcelain veneers. Porcelain has the added advantage of being extremely stain resistant year after year. You could have the whitest shade of teeth you want, and as long as you have to have the bonding removed anyway, why not go for the porcelain?

What is Invisalign reproximation?

Wednesday, January 7th, 2009

I am just putting on my last Invisalign aligner. By the way, they sure do look good. However, on its package is written “Please check the invisalign website for information regarding reproximation.” This concerns me. I looked up reproximation online. I do not have crowding at all. Do you know if this is printed on everyone’s last aligner?

Janice,
No, this isn’t printed on everyone’s last aligner package. Something seems not right about this message. I wonder if it was an error.

Reproximation is shaving of the sides of teeth. If you have a little crowding, but not enough to justify taking out one or two teeth, then we just shave a little off the sides of several teeth to get more space so that the teeth can be all lined up. But this is either done even before impressions are taken, in other words, the very first thing after the diagnostic work is done for the Invisalign. Or it is done very early in the treatment, during the wearing of the first few sets of aligners.

I’d ask your dentist if he or she knows anything about this comment. But I suspect that it is just an error by the Invisalign people – that they used this package for your aligners and didn’t realize it had that comment on it.

And we’re glad to hear that Invisalign has worked so well for you. There is an extremely high rate of patient satisfaction with Invisalign. And we just love doing this treatment for people.
