I have had porcelain veneers for over a year. I was told they are very stain resistant. However, I noticed that the sides are beginning to pick up stains. While I do smoke, as I mentioned, I was told these would stain less than my natural teeth. I like them, but I’m a bit concerned they’re defective because of the staining. Can I whiten them?

Dear Eddie,

You were correctly informed that porcelain veneers are more stain resistant than even your natural teeth. There are a few reasons that porcelain veneers will pick up stains. Let me say first that teeth whitening will not work. It only whitens natural tooth structure.
One is that the glaze, which protects the veneers, was damaged. This can happen if your dental hygienist uses something like a power prophy jet or acidulated fluoride during your check up. With the glaze compromised, your teeth will begin to pick up stains.
What you described is staining on the sides of the veneers, which is likely the margins where the veneers and teeth connect. Bear in mind that I haven’t examined you, but here are a couple of possibilities.
The first could be that there is a gap between your teeth and the porcelain veneers. These are called leaky margins. It would be a tricky fix, but it would need to be fixed. The stains you would be seeing from that is bacteria that is getting caught between your teeth and the veneers. This can lead to decay.
However, the most likely issue is that what the stain your seeing is more to the composite bonding than to the veneers themselves. This is a much easier fix. They will need to be polished. I would consider this regular maintenance.
Your dentist should have some ultra-fine polishing strips and a special ultra-fine aluminum oxide polishing paste that he or she can use in this area. The composite bonding is more stain resistant, so that is why they pick up stains more quickly. The smoking will add to this, but as long as you keep up with your maintenance, you should be fine.
