actually brits dont have bad teeth, britain beats the pants off Canada when it comes to edentulousness..and in the studies regarding missing decyaed and fileld teeth in recent surveys UK does much better than US.U in older population..US is better than both btw.
Not only that when you look at younger populations, Brits best American 12-year-olds by a score of 1.1 to 1.4 (lower is better), according to the World Health Organization.
Pakistanis on the other hand are considered third world in that area as well.
