i-NAML/ɪˈnæml/

Enamel here is the hard white outer covering of a tooth: tooth enamel; enamel erosion. Dentine lies beneath; cementum covers the root. Label the enamel on the tooth diagram, then the function. Mix-up: enamel vs the hard shiny paint (enamel paint) — use that only if the source names a coating or a tin; enamel vs emerald (already in a B2 list); do not write enamel for the whole tooth.
