How do I know if my breath is bad?

[tanyajack]

This isn’t a surprise, of course. You’ll remove tiny food particles and microorganisms that can lead to those volatile sulfur compounds. If you don’t floss, try it and then give the floss a sniff. Smell nasty? You’ve probably uncovered a breeding ground for unhealthy bacteria—and hopefully gained motivation to start flossing regularly. Keep in mind that gingivitis and periodontitis can lead to volatile sulfur compounds and bad breath, so regular dental checkups are a must.
