>Don't worry! Thank God for that! >My (naive) belief is that people associated the procedure with good health but weren't able to explain why it works. Also a naive assumption, but I suspect our ancestors understood completely that bad dental hygiene lead to both unpleasant smells and toothache. People are very good at avoiding both disgusting stimuli and pain! |
