Morphology

back + tooth

The meaning 'a tooth located toward the back of the mouth' is directly and transparently derived from combining 'back' (rear) with 'tooth' (a chewing/biting structure); it is a straightforward adjective+noun description (e.g., molar or premolar). This compositional pattern is cross-linguistically common and follows basic English modification rules, so a B1 learner who knows both words would readily infer the meaning.

Etymology

Back tooth comes from joining back and tooth to name a tooth at the back of the mouth, the molars used for chewing. That's why it means 'a tooth located toward the back of the mouth'.
