ALVEOLUS, in Anatomy, the sockets in the jaws
wherein the teeth are fixed. Some writers speak of
teeth growing without alveoli. Pliny mentions a per-
son who had a tooth in his palate. Eustachius relates,
that he saw a man who at 60 had a tooth growing out
of the middle of his fauces. Holler gives an instance
of a person whose teeth were of a piece with his jaws,
without any insertion into alveoli.
