I really love these late-19th century illustrations from a Turkish medical book, especially the image above that captures the intense pain of a toothache with both internal demons and an external, gnawing dragon. It's absolutely beautiful, isn't it?
The necessary curative measure, however, is less poetic:
UPDATE: Some readers have pointed out to me that the first image is Persian and the second is Turkish. Sorry about that! Corbis Images had them both listed as Turkish.
Yes, that's how you remove a bad tooth...
