Good discussions of dental work in Mexico.
“Los Algodones is a small 5-block square border town just south of Yuma, AZ (right next to CA/AZ split) that is pretty much dedicated to medical tourism. It has over 300 registered dentists, a slew of pharmacies (for cheap prescription drugs), multiple eyeglass doctors (cheap glasses), places to get inexpensive hearing aids…and probably a few more specialties I don’t know about.”
