(Chapter 11) Footnote 6:

Vesalius cites the fifth book of Galen’s De compositione medicamentorum secundum locos, where Galen writes “Now I wish to testify, without logical or physical proof, on behalf of those who say that the tooth itself feels pain. When I myself had a sharp toothache I investigated, having previously heard of the controversy, and I perceived clearly that the tooth not only hurt but also throbbed like inflamed flesh; and I thought it remarkable that this very affliction which we call inflammation can occur in a tooth which has a stony and rigid character.” (12.848.16ff.)
