Origin & History of “tooth”
Etymologically, a tooth is an ‘eater’. Its ultimate source is the prehistoric Indo-European base *ed- ‘eat’, which also lies behind English eat and edible. from this was formed the noun *dont-, *dent- ‘tooth’, whose descendants include Latin dēns ‘tooth’ (source of English dentist, indent, trident (16th c.), etc), Greek odṓn ‘tooth’, (source of English odontology (19th c.)), Welsh dant ‘tooth’, and prehistoric Germanic *tanthuz. This evolved into German zahn, Dutch, Swedish, and Danish tand, and English tooth. A variant of *tanthuz may lie behind English tusk.
