This Colgate advertisement shows the importance of a clean mouth.  It has humor to the photo by the woman placing the sleeping mask over her nose and mouth instead of her eyes like the man.  Only if the man used Colgate Plax (Complete Care) she would not have to worry about smelling his bad breath at night.  Colgate’s overall message is to keep a clean, fresh mouth because no one wants to tell you that you have bad breath.
