Dental Revision in Tijuana Mexico?

I'm considering having my dental revision procedure done in Mexico. The following three clinics seem promising, and have been recommended from Dr. Hulda Clark 's site and/or Tom MuGuire's site and/or Hal Huggins site.

I would really appreciate any onfo that anyne might have about any of these practices, good or bad:

Dr. Juan Carlos Hernandez, DDS
American Bio-Dental Center
Carolina Lopez Lena

Thank you,
