I had a root canal done when I was 25 or so. About 12 years later, I had this recurring abscess right up top of the gum, near my nose. Went to a dentist and she told me that the tooth was still alive. The root canal apparently didn't take! So I had to have it done again. And since I'm a Geordie and therefore hard as nails, I had it done by a student at the NY dental school. Dirt cheap as well. While I was there, she started telling me about lots of other stuff I should have done. So I said just go for it, whatever you need to do. I had to have an onlay, a filling and something else which I can't remember. And then she starts telling me you know, you have pretty good teeth with good spacing, they're just worn down a bit and one of the front ones was a little crooked. So before you know it I'm shelling out for some veneers as well, which were ridiculously cheap compared to a normal dentist. The whole thing took forever because the dental students aren't allowed to use assistants, they have to do everything themselves, and they have to keep stopping to go get a dental professor (did I get that right?) to check their work. So many appointments, and some of them 2 hours long. But now I'm in possession of a pretty good set of white chompers. I frigging hate going to the dentist though.
