Bifidobacterium lactis is a probiotic bacterium that has garnered interest for its potential to support oral health, especially in the context of oral surgery. Scientific studies suggest that probiotics, including B. lactis, may aid in reducing postoperative complications such as infections, inflammation, and delayed healing. The primary mechanisms proposed include modulation of the local immune response, inhibition of pathogenic bacteria, and enhancement of mucosal barrier function. While most research has centered on Lactobacillus and other Bifidobacterium species, B. lactis specifically has shown promise in in vitro and animal models for inhibiting periodontopathogens and modulating inflammatory responses in oral tissues.

Clinical trials directly investigating B. lactis in oral surgery patients remain limited. However, several small studies and systematic reviews have reported that probiotics can reduce postoperative infections and improve wound healing when used as adjuncts to standard care. For instance, a few randomized controlled trials have demonstrated decreased incidence of alveolar osteitis and improved healing in patients receiving probiotic lozenges or rinses post-extraction, though these often include B. lactis as part of a multi-strain formulation, making it difficult to isolate its specific contribution.

Overall, the evidence supporting the use of B. lactis for oral surgery is emerging but not yet robust. While there is a scientific rationale and early clinical evidence, larger and more targeted trials are needed to draw firm conclusions about its efficacy and optimal use in this context.
