Morphology

grinder = grind (semi-transparent) = grind + er

Formally 'grind' + '-er' is clear, but the meaning 'a molar/tooth' is a specific metaphorical extension (instrument for grinding) that some learners may not immediately infer.

Etymology

Grinder for a tooth comes from the same verb grind meaning 'to chew' or 'crush'. That's why a grinder is a tooth that 'grinds' food into smaller pieces, which we also call a molar.
