Dentists

Mice & Rats as Dentists

In many parts of the world it is customary to put extracted teeth in some place where they will be found by a mouse or a rat, in the hope that, through the sympathy which continues to subsist between them and their former owner, his other teeth may acquire the same firmness and excellence as the teeth of these rodents. For example, in Germany it is said to be an almost universal maxim among the people that when you have had a tooth taken out you should insert it in a mouse’s hole. To do so with a child’s milk-tooth which has fallen out will prevent the child from having toothache. Or you should go behind the stove and throw your tooth backwards over your head, saying “Mouse, give me your iron tooth; I will give you my bone tooth.” After that your other teeth will remain good.

Far away from Europe, at Raratonga, in the Pacific, when a child’s tooth was extracted, the following prayer used to be recited: “Big rat! little rat! Here is my old tooth. Pray give me a new one.”
Then the tooth was thrown on the thatch of the house, because rats make their nests in the decayed thatch. The reason assigned for invoking the rats on these occasions was that rats’ teeth were the strongest known to the natives.
