Hmm. Oops.

I was reading something the other day—I don't even remember what—and it contained a Q and A about sensitive teeth.

One of the most common causes, the doctor responding said, was improper toothbrushing habits. People brush side to side and using too much pressure, he said, which tears up your gums and wears on the enamel, creating tiny weak points which your common sensitivity triggers (hot liquid, cold liquid, sweet, and salty) use to infiltrate your tooth and cause you pain.

And as I'm reading this, I realize I'm one of the people he's talking about. I've always found the "little circles" method to be awkward at best, and gave it up for scrubbing side-to-side a couple years ago. Which, perhaps not incoincidentally, is when I started having cold sensitivity in a couple teeth. My most recent brushing habits are perhaps best likened to using a wire brush to scrape old paint off the side of a house; I've now mended my ways.
