To have a tooth for something, or to have a grudge against someone—often a stubborn tooth, or why not a hollow one if you’ve got fangs. Fangs to bite into life with gusto, or, on the contrary, to gnash your teeth until they grind. Expressions referring to our canines, molars, and other incisors pepper our vocabulary, reflecting the importance we place on our teeth. In psychoanalysis, Carl Jung and others even interpreted dreams featuring falling teeth as a sign of fear or resistance to change. Don’t smile, because it’s likely to spare the little ones from breaking their teeth on this anxiety that our imaginations, armed to the teeth, finally gave birth to a mouse to retrieve those little teeth and peace of mind without waiting for the chickens to grow teeth.
As you can see, today’s topic has us gaping in amazement as we discuss a scientific discovery that could explain why our teeth are so strong. Alban Desoutter and Frédéric Cuisinier both work at the Bioengineering and Nanosciences Laboratory in Montpellier—the former as a technical assistant and doctoral student, the latter as a faculty researcher. Using 3D technology, they discovered a mysterious structure hidden deep within our teeth, which they’ve dubbed “enamel drapery.” Their findings were published in the journal Archives of Oral Biology.
