I can never find plastic fangs that fit my mouth properly. Here's a way to make inexpensive plastic fangs that fit your teeth and stay put.
Note: Not recommended for small children. Since these are individual fangs, rather than a full set, they are potentially a choking hazard.
Step 1: Materials
- low-temperature thermoplastic (a.k.a. "friendly plastic", Ultra high molecular weight polyethylene, UHMWPE). Should be able to find it at a craft store.
- denture adhesive
- a glass container
- hot (nearly boiling) water
Step 2: Melt Some Plastic
This plastic melts at about 150F. Put some in hot water and wait for it to soften. It turns transparent when melted.
Step 3: Make a Fang Shape
Take a blob of plastic and shape it into a rough fang shape. Don't worry too much about the exact shape yet. You can shape it better once it's in place.
Step 4: Fitting
Shove the blob onto one of your canines and shape it to blend in with your other teeth.
If it doesn't come out to your liking, re-melt it and start over.
Step 5: Finishing Up
Remove the fang from your mouth and let it cool. It'll turn opaque when it returns to room temperature.
You should now have a plastic fang that fits your mouth perfectly. A small amount of denture adhesive will hold it in place.
