When my son lost his first tooth we didn't have a tooth pillow ready, so when his second tooth started getting loose we collaborated on a one-of-a-kind Tooth Monster. I suggested a tooth-shaped pillow and my son decided it should look like a hungry monster who craves little kid teeth.
Cut out 2 pieces of fabric in the shape of a tooth. Make sure not to make the root legs too skinny.
Next, have your kid design a tooth monster face. Cut out fabric in the colors and shapes they indicated and allow them to arrange the pieces on the tooth. when they are pleased with their design, sew them to one tooth template fabric. For the mouth, sew only the sides and bottom to form a pocket. Just to be safe, we sewed an extra pocket inside the mouth.
