These fake teeth sit between your teeth and lips. They're pretty comfortable and stay in place pretty easily. If you print them in a bright color or wear them at night they do an even better job looking spooky.

They print with no support, but a brim might help with adhesion problems.

They are sized for adults.

Trim the ends of the parabola if you experience discomfort. (Also, just don't wear them all the time).
