Why do movies often show young couples "in love" kiss first thing in the morning without brushing their teeth? Am I to assume that when someone is "in love" bad breath does not inflict significant damange it would otherwise? Or good practices of oral hygiene become totally irrelevant in life?
So when they show old married couples brushing their teeth standing side by side, is it that they are no longer "in love" or did bad breath finally win the challenge making them realize the importance of brushing and flossing?
