Morphology
The meaning 'a tooth from the first/temporary set' is directly derivable from combining 'primary' (first/initial) with 'tooth'. This is a straightforward adjective+noun compositional pattern with clear cross-linguistic equivalents, so a B1 learner who knows both constituents will readily infer the intended sense.
Etymology
Primary tooth uses primary to mean 'first' and tooth for the small teeth children grow. These are the first little teeth children have; they fall out and are replaced by adult teeth, so the name shows they are the child's first set.
