Tooth. n.s. plural teeth. [toð, Saxon; tand, Dutch.]
- The teeth are the hardest and smoothest bones of the body; they are formed in the cavities of the jaws, and about the seventh or eighth month after birth they begin to pierce the edge of the jaw, tear the periosteum and gums, which being very sensible create a violent pain: the dentes incisivi, or fore teeth of the upper jaw, appear first, and then those of the lower jaw, because they are the thinnest and the sharpest; after them come out the canini or eye teeth, and last of all the molores or grinders, because they are the thickest and bluntest: about the seventh year of age they are thrust out by new teeth which then begin to sprout, and if these teeth be lost they never grow again; but some have been observed to shed their teeth twice: about the one-and-twentieth year the two last of the molares spring up, and they are called dentes sapientiæ. Quincy.
