Fillings and crowns and root canals, oh my!

Well, I'm going to the dentist today and I am not at all happy about it. I have always had really good teeth, which is why it was so jolting to find out I need major dental work. Is this the first sign of impending middle age? Is the deterioration of my somewhat pearly whites just a harbinger of the trouble to come? Probably not. Most likely I've just neglected my teeth and the chickens are coming home to roost. 

Whatever, the fact is I have to have a filling, a crown, and a root canal today, and I wish I didn't.
