First , I got the toothpaste on the toothbrush , and then I wet the toothbrush head .  I brush the back teeth first , because those are the ones I usually miss . Then , I brush near the front of my mouth and my top and bottom teeth get a lot of attention . I like to make sure I brush my teeth for about 1 full minute .  After I brush all sides of all of my teeth , I spit out all the toothpaste , and rinse my mouth .
