KittyAngel From here, I decided to create the mouth next, while going back and forth between pre foaming the back of the dog. So, I used craft mesh and paper mache. It took 3 to 4 layers of the paper mache to make it functional. The teeth and tongue are made of Polymer Clay. When the paper mache dried, I decided to put Wonderflex on top to make it sturdy. When the Wonderflex set, I painted the inside of the jaw. I then placed the teeth and tongue inside. It took 25 minutes to create the teeth and tongue. Then it took 25 minutes to create the overall jaw. It took 50 minutes to make.
