1) Cut out a mouth-like shape from cardboard, and cover with latex and cotton wool for texture.
2) Use layers of cotton and latex to build up the gums
3) Use fake nails (preferably white) as the teeth, and insert them into the cotton while it's still wet (size all the nails in order beforehand)
4) Round off the tops of the teeth (nearest to the gum) and create the lines of the gums
5) Position the mask onto a respiration mask to strengthen and to make it more comfortable to wear (could also hole punch holes and use string instead) Cut parts of the mask if need be
6) Cover the rest of the mask with cotton and latex for texture
7) Use black and dark red paint behind the teeth
8) Use a mixture of reds and browns for the gums (I used alcohol activated paints for this)
9) Paint the teeth white (if not already) and add yellow, reds and browns to discolour
10) Darken any lines with black (make sure theres no harsh lines) and fade black all around the edges
11) Use scab blood around and the at the back of the teeth
12) Flick (with an old toothbrush or paintbrush) and dab (with a sponge) fake blood all around the mouth (tap the blood if it looks too harsh)
13) Use gloss varnish all over the mask when it's dry
TIP
-Measure the size of the mouth before you start making, as mine is far too big for my face
