A specialized cell that secretes enamel on the surface of developing teeth.
From Latin/Greek 'amel-' (enamel) plus '-blast' (young cell, from Greek 'blastos' meaning sprout). The compound was created in the 19th century with the development of microscopic dentistry.
Ameloblasts are like tiny enamel factories—they work only while your teeth are developing and then disappear! This is why adult teeth can't repair their enamel the way skin can heal: you run out of ameloblasts. Pretty cool that your teeth get built by cells that self-destruct.
