That's my dentist's latest hypothesis on why my teeth are eroding at the speed of light. There's really nothing that can be done about it. Cutting down on salty foods isn't going to help, and brushing my teeth five times a day doesn't seem to be doing much either. They seem hell-bent on getting me the bionic mouth. I suppose metal screws topped by fake teeth won't really be affected by salt. Or maybe they'll turn green, like the copper tops on buildings.
I'm done freaking out over things and am trying to be zen about it. After all, they also thought I might have AIDS, leukemia or this other disease that I can't pronounce but causes giant oozing sores to bust out all over your body. I don't have any of those, so maybe my salty spit isn't so salty either.
