Hal Huggins has a couple of books out about dentistry.  I fail to see how
one can argue with his conclusions.  He is  a dentist himself--N Dakota I
think-somewhere far north anyway.  Mexico is, imho, the best place to go if
you don't want to mortgage the house and sell your firstborn into
indenture.  And dental issues can very, very easily be matters of life and
death.  pj
