to do the tooth you can use paint, its easy to do this at it.

The eyes are a bit high up, and the red tattoo thing won't map well like that.

For the teeth, shade them with a soft light gray brush.

Check out a tutorial or two on mapping, as it will help you figure out what goes where.

Move the entire thing down a bit.
