Rating (out of 5): 2

Bifidobacterium bifidum is a probiotic bacterium that has been investigated for its potential benefits in oral health, including the management of gingivitis. Several scientific studies have explored the role of probiotics, including B. bifidum, in reducing inflammation and pathogenic bacterial load in the oral cavity. The proposed mechanisms include competitive inhibition of pathogenic bacteria (such as Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans), modulation of host immune response, and reinforcement of the oral mucosal barrier.

While the bulk of clinical research on probiotics for gingivitis focuses on strains like Lactobacillus reuteri and Lactobacillus salivarius, some pilot studies and randomized controlled trials have included B. bifidum—often as part of a probiotic blend. Evidence from these studies indicates modest improvements in clinical parameters such as gingival bleeding and plaque scores compared to placebo. However, the number of studies specifically isolating B. bifidum’s effects is limited, and most data come from small sample sizes or short-term interventions.

In summary, there is some scientific rationale and preliminary evidence supporting the use of B. bifidum for gingivitis, but the quality and quantity of evidence are currently limited. More robust, strain-specific clinical trials are necessary to confirm efficacy and optimal usage parameters for B. bifidum in gingivitis management.
