For a nation with such manky teeth (generally speaking) England (U.K in general) have one of the best and cheapest dental services in the world...you don't pay jack shit if you have a british passport.
Someone was telling me just the other day, a Scottish geezer that works with them, cause the dental care is free over there for residents/passport holders, and the gross amount of work his teeth required, it was cheaper for him to fly back to Scotland and have the work done than it was to just pay for that work here! MADNESS!!!
