At noon I had a dental appointment. Tartar builds up massively, especially on my bottom teeth, and a year and a half break is not a good idea. My new insurance plan is stingy with dental; it covers exam and cleaning with a small copayment, and everything else is according to a schedule. I opted to get x-rays since it's been a while and I've had pain occasionally. The fact that the pain doesn't linger means it's probably sinuses or something non-alarming, and indeed the films and exam showed nothing needing treatment. The dentist continued to notice the bone loss he first pointed out in 2004, but feels nothing needs to be done right now. So I had a cleaning and was on my way.
