Yoof and Goof

Anybody know where I could find a height/weight/age chart of yoof in Britain? I could use it in my current research...

And in an unrelated matter, I am finally looking into sorting out my goofy choppers. Apart from recommendations to look at Eastern European dental facilities, I'm a bit lost. Anyone know where I can find a good cosmetic dentist who won't charge me mortgage eating prices, I'd be very grateful.

Cheers! xxx
