That's how the dentists described my teeth, unfortunate!
They're just funny shaped, with gaps the wrong size, grooves in the wrong places. Before modern dental treatment I'm willing to bet that by aged 40 I'd be one of those people with no teeth! I think he's fixed it, the gap between two teeth was filling with food as he reshaped a filling on a previous treatment, he's now really gone to town on this filling to stop food getting in to the gap. Fingers crossed it seemed to have worked.
If not I have to make a phone call to my Dad and say I can't work tomorrow, I start my PGCE on Monday and taking a morning off to go to the dentists isn't an option I really want to take.
