How do I address this issue to my good friend.  My friend oral hygiene is less to be desired.  In fact it seems she dose not have any oral hygiene in place.   I normally let this go since I feel it is not my place to tell her how to take care of herself.

The thing is her breath is really bad.  I give her mints off handedly so that she does not think much of it. But other friends of ours have been making fun of her behind her back.  I do not join in but can not really stand up for her either since  they are right about her.

I feel bad but I also do not want to get involved.  I guess my question is should I tell her she needs to start doing something about her yuck mouth?  Or just do nothing ?  I am at the point that I really do not want to hang with her that much any more but I know her for over ten years and she is a really nice person.
