Hi, I've just noticed your post and would like to help if I may. I have been sculpting using polymer clay for years and a lot of the work I do is very small and detailed. To make very realistic teeth you would also need some translucent clay....mix the clay 1 part white to 3 parts translucent, when perfectly mixed roll your clay out to about a 1 1/2mm thickness. Now for some wire...you need wire that is quite fine, but also not too bendy ( an old fashioned hair grip works well ), cut 2 small squares out of your rolled clay and place 1 square on a small flat bakeproof plate. Take your wire or hair grip (if using a hair grip, cut the knobbly bits off the ends using pliers, and if using wire, shape it like a hair grip)
Now place the rounded top of the wire onto your clay and press down very gently, if your have liquid polymer clay then brush a little onto the clay and over the wire, otherwise baby oil will do just fine ( I hope you can follow this, its hard to describe without pics). Take your other small square of clay and place it on top of the first piece so the wire is sandwiched between the two, again press down gently. Now for the sculpting.....using any pics you have for reference, cut out the shape of your teeth using a sharp blade so you dont "drag" the clay, making sure the wire is inside the edges and in the middle. Dont cut your 2 teeth separately, just make a line down the middle with a toothpick or pointed tool, shape your teeth around the edges so the join is not noticable and also round off your teeth. Dont worry about them looking a bit rough because we come to the magic part now....using a small flat soft brush, dip it into some baby oil and remove the excess, now brush the teeth very, very gently in a downward motion...around the sides, down the line in the middle and then the front. Keep doing this until the teeth are smooth and to your liking.
Do not use too much oil or the clay will soften and become too thin. Now bake the teeth according to the instructions, usually at 130c for 10 to 15 mins. When baked leave the teeth to cool in the oven. To insert the teeth, first mark where they are to go in your baby's mouth and mark where the 2 ends of wire will go, you can shorten the wire at this stage, but leave enough to bend over once they are inserted. Using a small drill bit, drill holes where the wire will be pushed through..make sure you dont do them at an angle or your baby will have buck teeth
Carefully push the wire through the holes and check that the teeth are sitting right and then, whilst holding the teeth in place, turn your baby's head over and using long nosed pliers carefully bend the wires over enough to keep the teeth in place. It is a good idea to dab some glue on and around the wire to stop them from moving around.
Hey Presto...teeth that will never come out!!!
I make teeth this way for my goblins..only they have yukky ones
Hope this helps...Tina xx
