Dragon dentistry came about for 2 reasons.
1. The hubby has fun making teeth. While I am in the work room, often he had a chunk of clay on the kitchen table making all kinds of sets of teeth. I've got quite a few zip lock snack bags of teeth now: wide ones, long ones, twisted ones and some with colors mixed in.
2. The bake clay we've been using is a little brittle. It makes for delicate teeth. I've got one dragon mount above the love seat in the living room and when fluffing a blanket over the seat I've accidentally punched the dragon in the mouth and broken several teeth. I've done this a few times now. I know that this should cause the dragon to chew my arm off but this one just seems to roll his eyes as if to say 'not again'.
We've tried a number of different kinds and brands of baked clay to over come this problem but none of them are tough enough. People have suggested making ceramic, resin, metal, wood carved teeth but all of these seem to be costly and very time consuming.
While we were watching the show 'Face Off', one of the competitors on the show was creating a shark like creature. He mentioned using a low temperature polymorph plastic to make the teeth. They came out beautifully, and were quick to make. We looked this product up online and found a number of places we could get this at a comparative cost to the baked clay. We bought a small bag of it to try it out.
Wow! This stuff works great for the teeth! It is very tough yet has enough give that the teeth don't snap off now. So we are now replacing teeth in the currently finished pieces and will be using this for all future teeth, horns and claws!
The one on the left has the baked clay teeth. The dragon on the right has the new teeth.
