Last two years went to Rio Grande Valley area, Mission Texas. All the people we talked to go across the border to Nuevo Progreso for medicine and dental work. I have Tricare so don't need nor want to get cheaper medicine nor dental work. I understand the reason for it as my mother and father go there every year (in their late 80's) and go there for their meds and work. Most of the places I take them speak excellent English, have graduates of US schools and medicines that look and read like their US counterparts.
