We have been to several Mexican dentists over the years from Las Palomas south of Deming,NM to Valle de Juarez near Lake Chapala to San Miguel de Allende to Algodones near Yuma,AZ. Every office we have seen has been immaculate and the dentists all excellent with a high degree of care. As far as sanitary - each room is cleaned by a person whose sole job it is to clean and sanitize between patients. They use some sort of thin film like "Saran Wrap" but tinted blue to cover every knob on every cabinet and every surface anyone might touch. The use the latest technology and have the most modern facilities. I can't single out any one in particular in Nuevo Progresso as we have not yet had the occasion to go there. Lots of great medical professionals all over Mexico. Many people go to clinics in different parts of Mexico for excellent health care - including lots of "elective" surgery. We'll be back in Algondones very soon for another crown ($170US).
