heyas; you know you can use the grouping tool and magnets... put the skin and mouth-skin into a group, and the teeth/gums materials into another (are the gums separate or part of the 'mouth' material? can't remember.) anyway, once you have the skin group separated from the teeth/gums, you can tell the mag zone to only affect the group. so you could use a magnet to pull the lips and facial skin all around anywhere, and leave the teeth where they are.
