Tooth Woes

So I am losing another tooth. I think it is a combination of genetics and the best of Socialist dental care in my childhood because I do not smoke, do not drink sodas, do not have diabetes, do not take meds that cause tooth decay,brush rigorously, and yet, I have another ugly cavity that according to my dentist requires either root canal or an extraction. Since he honestly told me the root canal has a 20-30% failure rate, I decided to have the sucker removed, since, as my dentist sternly reminded me 'we have a lot of work to do' and I'll have a buch of reconstruction to be done anyway. My lower jaw is in a pretty sorry state, apparently.
So-I'll be in a dentist's chair at 230pm today...after that's it's painkillers and bedtime for meee...
