Lately, my daughter has been asking me a lot of questions that seem to have the sole purpose of getting me to floss more. A few days ago it was whether the enamel on our bathtub is the same stuff as on our teeth.
Today it was, “What does a toothache look like?”
Since I’m not terribly interested in developing a toothache just to give her a live demonstration, we asked the iPhone this question, and found this page on abscessed teeth right away (thanks Dr. Internet). It includes a diagram of a cross-section of a tooth which was, thank goodness, good enough.
We then got sidetracked looking at a story about the oldest known toothache, which happened some 275 million years ago to Labidosaurus hamatus, an omnivorous reptile who lived on land and wore out his teeth chewing some very tough plants and crunchy insects.
