In a prolonged TEOTWAWKI situation, I guess we'll just endure the pain, lose our teeth, die of heart attack, etc., like our ancestors did. Modern medicine requires a huge supporting industry in order to work. It's not just some guy with a box of herbs.
If Franklin isn't worth the paper he's printed on, barter. The dentist then barters to have more dental supplies to use.
This may not be easy but is it doable?
