Morphology
The compound is a straightforward adjective + noun: 'dental' (relating to teeth/dentistry) modifies 'amalgam' (an alloy used in dentistry), so the meaning 'an amalgam used in dental work' is directly derivable from the parts. Although somewhat technical, this compositional pattern is regular and cross-linguistically common, so a B1 learner who knows both constituents would understand the MWE.
Etymology
Dental amalgam comes from the word amalgam, which means a 'mixture'. Dentists mixed mercury with metals like silver to make a soft paste they could press into a tooth cavity, and when it set it became a strong 'filling'. So dental amalgam means the metal 'filling' dentists use to repair a tooth.
