Here is something different which I am sure we have all needed at some point in our Reborning, Doll's Teeth. They are 2 little toothies, can be used as upper or lower teeth.
Small - 4mm x 7mm
You will get only the one set of teeth
As you can see there is a little bit above the tooth, simply make a very fine cut in vinyl, slip them in with a little glue and voila, you baby has some toothy pegs.
