I spent some time struggling with this. I found it very difficult to rig the gums and teeth the way I wanted it. I largely followed the advice here at this makehuman forum posting, but I added a few tricks of my own.
I put in separate bones for the "nose" (i.e., top row of teeth) and the "chin". I assigned all of the gum vertices to either the nose or chin Vertex Group after I selected them in a side view in Edit Mode. I then had to do a little weight painting to get the gums to go back where they belonged. Despite the parenting to the chin bone, and having been assigned to the chin vertex group, many of these vertices were still parented part way to the nose.
Next up: Eyeball and smile rigging.
