Morphology

retainer = retain (transparent) = retain + er

The dental device literally 'retains' teeth in place, a straightforward nominalization from the verb 'retain'.

Etymology

The word retainer comes from Latin retinere, with re- meaning 'back' and tenere meaning 'to hold'. So a dental retainer is something that 'holds' your teeth in place after braces.
