You’ve probably watched at least one breath mint commercial where two love interests are just about to kiss – and then one recoils at the stench coming from the other’s mouth. Bad breath is generally seen as undesirable, but getting rid of it isn’t always as simple as popping in a few breath mints or biting down on some chewing gum. For some, it’s a chronic problem that needs to be addressed more strategically.

If you’re looking for a more long-term solution to bad breath, the science behind eating yogurt could help!

What Causes Bad Breath?

One of the reasons bad breath tends to be stigmatized is it can be a sign of poor oral hygiene. Leftover food particles and bacteria buildup are common contributors to an unpleasant mouth smell.

However, the ultimate cause of bad breath is chemical. Certain bacteria produce foul odors as they grow, and some compounds (like hydrogen sulfide or enzymes found in garlic and onions) are naturally pungent. Thus, the aroma of your smile can also be dictated by genetic, medical, and dietary factors that influence the types of bacteria living in your oral biome.

How Does Yogurt Help Freshen Up Your Breath?

Studies have found that the active probiotics in yogurt are particularly effective at fighting the various bacteria and compounds that contribute to bad breath. This even includes anaerobic bacteria – the same type that can cause gum disease! Eating yogurt on a regular basis seems to lower the smelly bacteria content in the mouth and help freshen up the breath.  

How to Fight Bad Breath with Yogurt

According to the research, the magic ratio is six ounces of yogurt per day, which is about the size of a standard single-serving container. Plain, sugar-free yogurt also seems to be more effective than flavored yogurt.

In addition to incorporating more yogurt in your diet, remember to maintain good oral hygiene by:

  • Brushing your teeth (and tongue!) twice daily
  • Flossing once per day
  • Changing your toothbrush every four months
  • Using a dentist-recommended mouthwash
  • Drinking plenty of water
  • Asking your dentist for personalized tips

While yogurt doesn’t replace good ‘ol fashioned brushing and flossing when it comes to combating bad breath, eating more of it can be beneficial for those with more persistent symptoms. Give it a try and see if yogurt is an easy solution for your smile!
