1. tooth powder, toothpaste
   • Pliny the Elder, Natural History, XXVIII, 28, 11, 49, §182

     Efficax habetur et caprino lacte conlui dentes vel felle taurino. Talorum caprae recentium cinis dentifricio placet et omnium fere villaticarum quadrupedum, ne saepius eadem dicantur.

     It is also held to be very efficacious to wash the teeth with goat milk or gall from a bull. The anklebones of a nanny goat recently killed, [burned to] ashes is good as a toothpaste, as are the bones of all quadrupedal farm animals in most cases, to avoid repeating this too much.
