Also went to the dentist today for a cleaning. Got no surprises: everything checked out fine, got a clean bill of dental health.
But that in itself was a pleasant surprise, and a bit of vindication. See, I've been low-carbing since Jan 2003. One of the many statements made by some of the authors I've read is that our distant ancestors (pre-agricultural, anyway) had much better dental work, whereas poor teeth appeared hand-in-hand with the mass consumption of grains. The conclusion is that our dental problems would be reduced or eliminated by eliminating large quantities of carbs from our diet.
"So", you're sitting there saying, "what does a 6-month no-cavity report mean?" Well, it's been at least 2 years, and perhaps 4 since my last cleaning, and I had virtually no tartar build-up. I brush twice-daily and floss 2-3 times monthly, but otherwise, just eat "normally".
So no, it doesn't "prove" anything, but it just feels like one more little thing in support of this way of eating.
