. Word History: Eating, biting, teeth, and dentists are related not only logically but etymologically; that is, the roots of the words eat, tooth, and dentist have a common origin. The Proto-Indo-European root *ed-, meaning “to eat” and the source of our word eat, originally meant “to bite.” A participial form of *ed- in this sense was *dent-, “biting,” which came to mean “tooth.” Our word tooth comes from *dont-, a form of *dent-, with sound changes that resulted in the Germanic word *tanthuz. This word became Old English tōth and Modern English tooth. Meanwhile the Proto-Indo-European form *dent- itself became in Latin dēns (stem dent-), “tooth,” from which is derived our word dentist. We find a descendant of another Proto-Indo-European form *(o)dont- in the word orthodontist.tooth
