A study published in the journal Current Opinion in Gastroenterology back in 2011 found that probiotic supplements actually help replace odor-causing oral microbes with beneficial varieties, effectively nipping bad breath in the bud. Other studies have identified specific probiotic strains such as Lactobacillus salivarius that directly target harmful bacterial strains in the mouth, and reduce or eliminate the volatile sulfur compounds (VSCs) responsible for causing bad breath.
5. Include More Raw Foods In Your Diet
Eat more carrots, celery, and apples. Crunchy fruits and vegetables, preferably organic, that are rich in fiber are also beneficial in the fight against bad breath.
