All right, Nighthawk, just so you know that I really am crazy...

The Project Gutenberg EBook of The Cruise of the Cachalot, by Frank T. Bullen (EBook #1356)

From "Chapter VIII. Abner's Whale":

After every sign of the operations had been cleared away, the jaw was brought out, and the teeth extracted with a small tackle. They were set solidly into
a hard white gum, which had to be cut away all around them before they would come out. When cleaned of the gum, they were headed up in a small barrel of
brine. The great jaw-pans were sawn off, and placed at the disposal of anybody who wanted pieces of bone for "scrimshaw," or carved work. This is a very
favourite pastime on board whalers, though, in ships such as ours, the crew have little opportunity for doing anything, hardly any leisure during daylight
being allowed. But our carpenter was a famous workman at "scrimshaw," and he started half a dozen walking-sticks forthwith. A favourite design is to carve
the bone into the similitude of a rope, with "worming" of smaller line along its lays. A handle is carved out of a whale's tooth, and insets of baleen,
silver, cocoa-tree, or ebony, give variety and finish. The tools used are of the roughest. Some old files, softened in the fire, and filed into grooves
something like saw-teeth, are most used; but old knives, sail-needles, and chisels are pressed into service. The work turned out would, in many cases,
take a very high place in an exhibition of turnery, though never a lathe was near it. Of course, a long time is taken over it, especially the polishing,
which is done with oil and whiting, if it can be got—powdered pumice if it cannot.
This would be in the 1890s.

Perhaps you could take up scrimshaw art on people's teeth at the "Renfairs."
