Learn how to draw a mouth in four steps! This free online people-drawing tutorial will give you the techniques of an artist in no time flat. You'll easily follow along as the lesson teaches you the sketching, drawing, and coloring phases of creating the image (it includes a special coloring page). These phases can move forward only whenever you choose, so staying with them is simple! Did you know that toothbrushes have only been mass-produced since about 1780? People probably had very dirty mouths before then!
