Would only add that if the teeth weren't fixed in a formalin solution
almost immediately after extraction that the longevity
will be short, maybe very short.
Even if the modifications can be done on unfixed teeth,
the teeth will eventually crack, fracture, and split.
Even "fixed" teeth will do this.

Though it may not seem so to the average person, teeth are still
biologic tissues and as they dry out they become brittle.

One would only hope that this is part of a Halloween costume
for a limited time use and not something intended to be used
as jewelry on a long term basis.

Have helped a few patients with fangs for Halloween costumes
and have been asked to make permanent porcelain fangs but
have yet to encounter the request for wisdom teeth earings.
A novel concept to say the least, with LED's no less.

If you succeed in your quest please send us some pictures.
Should be quite *interesting*.
