to this:
We met... I don’t know, he doesn’t brush his teeth, or he doesn’t change his cowards, or maybe a disease – but we communicate now only at a pioneering distance. How would you tell such a good man?

From personal practice:
I met a girl, the smell from her mouth was... not even the smell, the smell. Several times tactically hinted, then directly advised going to the dentist. Hysteria and separation.
In a couple of months I will find out that she is in the jaw-face, with the most difficult suppuration.
I understand not funny. But still do not soak up the problems and take comments into account, with health do not joke.
