Could you be a bit more specific on your terminology of “Deer” teeth.
I think what you are referring to are the vestigial ivory tusks that
are taken from Elk. If they are Elk Ivory, they will cut and polish
beautifully and need no covering or treatment. They will wear very
well for years.
Just a quick note, if you haven’t cut the tusks yet, be sure to
bleach them and remove any fleshy material to sanitize them first.
