Most people know certain foods and drinks will stain their teeth. Coffee, for example, is well known as an anti whitener, as is tobacco. But did you know there are certain foods that act as natural abrasives and help keep your teeth their shiny best?

Let's take a look at some of the culprits and heroes for that pearly white smile of yours. First, here are the bad guys:

Red Wine: Great for your heart, but not so good for keeping your teeth white. Whoever said there's always a trade off is right in this case.

Blueberries: A fruit that's really high in antioxidants and just as high in staining power.

Soda: Specifically, dark colored sodas, or do you call it pop? Either way, it'll stain your teeth.

Here's a good rule of thumb: If it'll stain your favorite t-shirt, it'll stain your teeth.

And now, here are a few of the hero foods, at least for keeping your teeth white ...

Apples: Apples have a natural abrasive in them which helps keep your teeth clean and free from debris. You can probably taste the natural abrasive as you bite into the apple. And while an apple a day doesn't keep the dentist away, its natural abrasive powers are but one benefit of the apple.

Carrots: See our plug for apples.

Lemons: Lemons are a natural bleach, which is why you see lemon as a common ingredient in cleaning solutions. And while munching on lemons isn't practical or likely, even a quick swish of lemon juice from a fresh lemon will help prevent staining.

Cucumbers: Did you know cucumbers help your mouth produce saliva? Saliva is one of the best ways to help remove staining agents and debris from your teeth.

So if you're looking for your brightest, whitest smile, consider adding some of these foods to your diet. And as always, follow a consistent routine of brushing, flossing, and rinsing. A good whitening rinse is one of the best ways to keep your smile in tip top shape.
