Morphology

milk + tooth

The meaning is directly compositional: 'milk' evokes infancy/nursing and 'tooth' is literal, so a learner who knows both words can infer it refers to a child's/temporary tooth. This construction is cross-linguistically common (e.g. Spanish 'diente de leche', French 'dent de lait'), supporting immediate understandability at B1.

Etymology

Milk tooth comes from a simple picture: these are the first teeth a baby has while it drinks milk. They are called that because they are 'temporary' and later fall out and are replaced by adult teeth.
