Because I lived near S.D. Ca. I know there are dentists in Mexico that may be more cost effective than using a dentist in the States. I think also that there is a very popular town in Mexico where there are a whole glut of dentists, it's near the AZ. border, it starts with an A, I'd have to research that..I can't recall the name. But people go by the tour bus loads from the States there to take care of their teeth, many of our elderly especially.
If you are wondering what kind of dentists Mexico might have, I'm sure they have all sorts, but I did also read in the same article that because they pay so much less for their equipment, many of them have more new and modern equipment that many of our dentists and even our more elite dentists might not be able to afford here in the States.
