The only way to accurately answer how much a dog's hair will weigh when shaven is to weigh it like Gotap_d has done and the dogmen who practiced this method that I know and asked to make a response to this post.

Also think about this, how does a woman's prickly leg, or something else feels in your mouth when she is not clean shaven?

To think dog hair is armour against the pearly whites is kind of laughable to me, protection from the elements yes.
