You state that some people say good things about your Tijuana dentist. Fair enough. A simple Google search reveals that a number of people are far less impressed with him.
You claim that Dr. Stephen Barrett is a quack. That "quack" graduated from Columbia Medical School and practiced real medicine for decades. He has won numerous awards for his consumer protection work. He taught at Penn State. He has been a strong advocate for many years against health-related frauds and myths. He is a scientific advisor to the American Council on Science and Health. He has written over 2000 articles and spoken at a large number of universities. What a quack. I'm sure your dentist from Tijuana is equally qualified. Speaking of his qualifications, is he currently board certified? By board certified, I'm not talking about some obscure holistic board. I'm referring to the Mexican Dentists Association.
Your rejection of modern dentistry is as interesting as your rejection of reasonable advice from the American embassy in Mongolia. Is the American government involved in yet another conspiracy? Is President Obama is a pod for the American Dental Association? This conspiracy may be deeper than you think. I believe the American embassy, for decades, has been referring Americans travelling abroad to dentists who use (to use your language) horrendous U.S. technology.
By the way, do you happen to have some connection to this Tijuana clinic that you have been opening promoting?
