This is what I made today.
They are made of medical grade thermal plastic and individually placed in Papa Fuzzy’s mouth.
Basically, I cut a tiny piece of thermal plastic and lower it into boiling water with a slotted spoon. I pull it out to shape it using a flat surface and a scoring tool (my fingernail).
For the molars, I shaped two pieces of the plastic and stacked them to get the width I wanted.
You can juuuuust barely see his tongue in this shot.
I’m particularly happy with the molar, but I may wind up not making any more than that. I just want the hint of white when he opens his mouth and having a full set of teeth might break the “cute” aspect of him. Although I’m using ecru thermal plastic, it’s still a little stark for his mouth.
