Before changing up your eating habits, it should first be noted the results didn’t indicate that probiotics permanently solved halitosis.

“The data shows that there’s some potential short-term benefit to probiotics, but it doesn’t really hold up long-term,” said Messina.

Holland added that “having a more diverse microbiome may allow the body to digest a wider variety of foods and thus stave off halitosis.”

“It is important to consume a diet that helps propagate a diverse quantity and quality of various gut bacteria to help maintain not only gut and oral health but overall well-being too,” Holland noted.

Experts say that maintaining a balanced diet, such as the one recommendedTrusted Source by the American Heart Association, can add some healthy variety to your meals.

Regarding how you get probiotics into your body to begin with, Holland said, “the broad recommendation would still be to ingest the foodstuffs first. If you aren’t going to intake the food items, supplements are a great option.”
