Teeth and horns are modified hair follicles which is why,
if you think about it, smell like burning hair when you
get them hot - as in grinding on them at 30K rpms with
a dental bur or bandsawing them at 1K fpm. Because
they're modified hair follicles they each have a nerve or
several nerves - the removal of which, in the case of
a tooth, is called a root canal.

Antlers - I'm not sure about.

Bone.

An intelligent design conceals its secrets from the unthinking.
