Oral hygiene at work/home

This is not just at one company and have observed everywhere. It's so difficult to bear people with bad breath sitting in small team rooms for meetings. Rather than giving some useless swag, my request for all companies is to promote some oral hygiene products like tongue scrappers during the health/benefits fairs so people can start getting aware of such products. I believe some people don't know they have to clean their tongue as well and not just brushing teeth. I am sure several of you faced this issue at work. Hoping this post solves issue for at least few people.
