Back and forth And around in circles.
There really isn't a fun way unless you have some sort of light-up tooth brush.
the right way to brush your teeth is in a circular motion,always brush your gums to.brush for at least two minutes.
It really doesn't matter, but it would help if you floss and brush in small, rapid circles.
Circular motions, make sure to brush inner sides, outter sides and the top of every tooth. Then flaws beetween each tooth.
