Thanks for the comments. As for the mouth interior, I made the teeth (warped cones), and then duplicated their base circles as separate pieces to form the gums.... connecting the outer points to form the top of the gums as a single piece. After that, I selected the outer edges of the whole thing, and grew outward a bit, then moved that outline down, and grew again, moving the new outline down further, stretching and arranging the expanding areas as needed to get the form ... as shown here in final shape (not going into the tongue development, but you can see what I mean for just the gumline alone)...
Look at the below snd you can see the tooth-base circles and how I expanded from them.
I then placed the original teeth again as separate pieces, moving them about a bit to where it looked good to me, as if they are growing out of the gums.
