Lactobacillus gasseri has been investigated for its potential benefits in oral health, particularly in the context of oral surgery and postoperative recovery. The scientific basis for its use stems from its probiotic properties, which include the ability to modulate the oral microbiome, inhibit pathogenic bacteria, and potentially reduce inflammation. Several studies have shown that L. gasseri can suppress the growth of periodontopathogens such as Porphyromonas gingivalis and Streptococcus mutans, which are implicated in postoperative infections and delayed healing.

Randomized controlled trials and pilot studies have demonstrated that oral administration of L. gasseri (in lozenges or tablets) can decrease pathogenic bacterial load, reduce gingival inflammation, and promote a healthier oral environment, conditions favorable for surgical recovery. Some studies have also reported reduced incidence of postoperative complications such as infection or delayed healing in patients using probiotics, though these findings are not universally consistent and often involve the use of multi-strain probiotic formulations, making it difficult to isolate the effect of L. gasseri alone.

Overall, while there is a growing body of scientific evidence suggesting potential benefits, the quality and quantity of data specific to oral surgery patients is moderate. Larger and more rigorous clinical trials are needed to confirm these effects and establish standardized protocols for probiotic use in oral surgery settings.
