I had to do a quick check if python do have teeth and thus use braces. My initial thought was that they do not as the most prominent teeth on snakes are fangs and python are not venomous. They do have teeth for holding their pray as they constrict it.

Pythons use their sharp, backward-curving teeth, four rows in the upper jaw, two in the lower, to grasp prey which is then killed by constriction; after an animal has been grasped to restrain it, the python quickly wraps a number of coils around it. Death occurs primarily by cardiac arrest.
