So this is that 1 out of 10 dentist who doesn't reccommend all those new toothpastes.
Dr Khaled Kasem, of the international dental chain Impress, has said people should kiss for four minutes a day, purely for the health of their teeth.
"The main benefit of kissing is that it produces more saliva in your mouth" they began.
But before you go and throw your toothbrush away, Kasem went on to say that a cheeky kiss shouldn't replace actually brushing your teeth.
"The only negative impact of kissing is when people are sick, have a cold sore or already have bad oral hygiene. Otherwise, kiss away - but keep brushing and flossing."
