well, my dentist tells me that i grind my teeth!! (my friends reckon i need a psychologist as opposed to a dentist!)
but seriously, my dentist said to me that if i get crowns (and he was talking about here in eire) that i would probably chew my way through them in no time. he said that my crowns (which cant be done according to him till after the braces) would cost about 5 or 6 grand - he reckons i need the entire top row done - due to the damage i've done from the grinding! and the braces will cost, in ireland, c. 5 grand.
so thats over ten grand. so, i'm sure you can appreciate how someone like me is attracted by these cheapo options? i have to say, my dentist is spot on, and he doesn't stand to make a bean out of me getting the work done here (unless there's some underhand commission type system in operation, which i dont believe there is).
