How do you confront dentistry when there is no dentist? This is an interesting question as I had a tooth go bad (infected nerve) when I was working in the jungles of north Myanmar. It was a molar and it was somewhat painful although I did have some benzocaine to deaden the pain. I had another five or six weeks before I could get out of the jungle and get to a "real" dentist in Hong Kong or Singapore. Since then I had thought about how to deal with tooth problems when there is no dentist.
I found an online book "Where There Is No Dentist" which may be of some help and is designed for those in the Third World. The book is also available in hard copy from Amazon. It is part of a series including the book "Where There Is No Doctor" from the Hesperian Organization.
