Morphology
The meaning is directly compositional: 'pulp' names the nerve-and-blood tissue inside a tooth and 'cavity' denotes a hollow, so a learner who knows both constituents can infer it is the hollow containing the pulp. This noun–noun compound follows regular English formation and parallels constructions in other languages, making it immediately understandable to B1 learners who know the parts.
Etymology
Pulp cavity literally names the hollow inside a tooth: pulp is the soft inner tissue and cavity means a hollow space. So, pulp cavity refers to the tooth's central space that holds 'nerves' and 'blood vessels' and can become infected and painful.
