Making teeth that stick out?

I want to make tusks for orcs, trolls, etc., but I'm trying to think of how they would work. For instance, if I made custom teeth, would they stick out of the mouth like intended, clip through, or completely disappear when my sim closes their mouth? If I made them as an accessory, how could I weigh them to follow the lower jaw? Thanks in advance for any advice!

Edit: I have made tusks as teeth and they are working, however, only for vampires. I did check the boxes to make them available to all occult types, but it still only appears for vampires.

Edit 2: I found a solution to the last problem, I just needed to start with human teeth and give it the tusk mesh that I made from vampire teeth.
