If you're using Chrome, the right column of this blog isn't displaying correctly. Switch to Firefox. If you're using the iPad, you're a tool. If you're using IE, go kill yourself.
(This person is kinda upset that I dissed their favorite browser. I actually use Chrome and I like it, but for some reason the layout here is different than on Firefox. And of course, the iPad and IE just plain suck. You tool.)

How does flossing help increase life expectancy?

I was somewhat skeptical of it at first but I guess it's true. Here's how flossing protects against heart disease:

When you floss, you help prevent your gums from becoming inflamed. That's a good thing. What is happening when your gums are inflamed is that you have a chronic bacterial infection in your mouth. This harms your arteries through two mechanisms: the bacteria find their way in to your arteries and hang out (causing plaques), and your body mounts an immune response to the bacteria in your mouth, causing inflammation (which in turn can cause your arteries to narrow). This makes it hard for your heart to do its job and can lead to heart disease.

No one knows for sure how many years that adds to life. Estimates range from 1.5 to 6.
