Etymology: "Odontalgy" is an older spelling of "odontalgia," and its parts are easy to read off: "odont-" comes from Greek "odous" (genitive "odontos"), meaning tooth, and "-algia" comes from Greek "algos," meaning pain. Put together, the Greek noun "odontalgia" meant toothache, and English took it up through New Latin, the scientific Latin used by early modern and later naturalists and physicians to name conditions and organs. The pattern is the one behind many medical terms. Greek-derived "-algia" appears in "neuralgia" (nerve pain) and "myalgia" (muscle pain), so "odontalgy" slots into a set of clinical labels where the first element names the body part and the second names the sensation. Its spelling with "-y" rather than "-ia" follows a common older English habit of dropping the Latin or Greek ending in favour of "-y," as in "neuralgy."
