Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Lactobacillus species have been investigated for their potential to support oral health, including after oral surgery. The rationale for their use lies in their probiotic properties; they can modulate the oral microbiome, inhibit the growth of pathogenic bacteria, and potentially reduce inflammation. Several clinical studies and systematic reviews have examined the adjunctive use of Lactobacillus-containing probiotics following oral surgical procedures such as tooth extraction, implant placement, or periodontal surgery.

Evidence suggests that Lactobacillus supplementation may help reduce postoperative complications, particularly infection and inflammation, by competing with pathogenic bacteria and modulating host immune responses. For example, randomized controlled trials have shown reduced levels of periodontal pathogens and decreased signs of inflammation in patients using Lactobacillus probiotics after oral surgery or scaling and root planing. Some studies also report reduced postoperative pain and improved healing, although results are not uniformly consistent.

Systematic reviews (e.g., Gruner et al., 2016, and Inchingolo et al., 2020) indicate that while the use of probiotics, including Lactobacillus, is promising, the overall evidence quality is moderate due to heterogeneity in study designs, probiotic strains, and outcomes measured. Most experts agree that probiotics may be a useful adjunct but should not replace standard surgical aftercare. In summary, there is moderate scientific validation for the use of Lactobacillus in supporting oral surgery recovery, but further high-quality studies are needed.
