Here's the trick. The hinges pop right back out so I used expanding spray foam in the gap to seal em in. If one pops out I recommend the same.

Step 7: A Little Cooler
Step 8: Dental Care
Start with anchoring teeth to jaw with screws, they are canted outward to not make contact with opposing jaw when closing.
Pinch and form play-doh (white) into properly sized teeth. I then painted them with Plasti-cote liquid rubber. This gives them a nice toothy color while effectively keeping play-doh soft like in the jar. Provides some resilience to accidental contact.
Unfortunately these do occasionally break, or get yanked out, luckily the supplies to fix are cheap.
One last bit on painting. The plastikote will also eat the foam if it drips off play doh. Go slow, and coat a few times for sturdy coating. Any drips onto vynyl can be rubbed and peeled off neatly when cured.
