I start with my mouth very close to you. I open it wide and hold it there, giving you time to take a detailed look inside, seeing every tooth, my tongue, the depths of my throat. Then I brush, I’m so close to the camera you can hear the brush sliding against my teeth. I show you the whole process, sticking my tongue out, showing my uvula, opening and closing my throat, letting some saliva drip from my mouth. And when I’m done, I show you again how my whole mouth looks when it’s clean.
