faire ses dents

Meaning: A baby is teething and developing their first teeth.

Language: French

Literally: to make one's teeth

Category: Body & Senses

Origin: Plainly literal in its first sense: an infant's first teeth pushing through the gums, from Latin dentire, to grow teeth, the verb behind dentitio and the modern dentition. The figurative sense — someone or something new, still cutting its teeth on a task — rides on the same discomfort every set of new teeth causes on the way in: painful, disruptive, and unavoidable if the thing is ever going to be able to bite into anything at all.
