Probiotics and Oral Health: A Systematic Review

Probiotics have gained significant attention in recent years for their potential health benefits, including their role in maintaining oral health. A systematic review published in PubMed suggests that probiotics usage could be beneficial for the maintenance of oral health, specifically in decreasing the colony forming units (CFU) counts of oral pathogens.

Tooth decay, periodontal diseases, and halitosis are among the most common oral diseases that people suffer from during their lifetime. The composition of oral microbiota plays a crucial role in the development of these diseases. Streptococcus mutans, the most important caries-causing species, is known to contribute to tooth decay. Probiotics have shown promise in adjusting the oral microbiota and reducing the number of pathogenic bacteria in the human intestine.

Probiotics for Tooth Decay Prevention

Probiotics have been extensively studied for their potential role in preventing tooth decay. In vitro and in vivo studies have demonstrated that different strains of probiotics can have health-giving effects, particularly their anti-pathogenic effect in the oral cavity. Randomized clinical trials with long-term follow-up periods are needed to confirm the efficacy of probiotics in preventing tooth decay.

Role of Lactobacillus Bacteria and Bifidobacteria

Lactobacillus bacteria and bifidobacteria have been the focus of many studies investigating the role of probiotics in oral health. These beneficial bacteria have shown the potential to modulate the oral microbiota and reduce the risk of dental caries and periodontal diseases. Their ability to inhibit the growth of pathogenic bacteria and promote a balanced oral microbiome makes them promising candidates for oral health interventions.

Probiotics and Candida Yeast Infections

Candida yeast infections can cause oral thrush, a common fungal infection in the oral cavity. Probiotics have been studied for their potential to prevent and treat Candida yeast infections. While the research is still in its early stages, preliminary studies suggest that certain strains of probiotics, such as Lactobacillus rhamnosus and Saccharomyces boulardii, may have anti-fungal properties and could help in managing Candida infections.

Probiotics and Halitosis

Halitosis, or bad breath, can be caused by various factors, including oral bacteria. Probiotics have shown promise in reducing halitosis by promoting a balanced oral microbiota and inhibiting the growth of odor-causing bacteria. While more research is needed to establish the specific strains and dosages for halitosis management, probiotics offer a potential natural solution for those struggling with bad breath.

The Potential of Postbiotics

In addition to probiotics, postbiotics have emerged as a novel area of research in oral health. Postbiotics are non-living biological compounds derived from probiotics. They have shown potential in improving oral health by promoting a balanced oral microbiota, inhibiting the growth of pathogenic bacteria, and reducing the risk of dental diseases. Further studies are needed to explore the specific mechanisms and applications of postbiotics in oral health.

Conclusion

The systematic review on probiotics and oral health highlights the potential benefits of probiotics in maintaining oral health and preventing common oral diseases. While promising, further research, including randomized clinical trials with long-term follow-up periods, is needed to confirm the efficacy of probiotics and identify specific strains and dosages for different oral health conditions. In addition to probiotics, postbiotics offer a promising avenue for improving oral health. As research in this field progresses, probiotics and postbiotics may become valuable tools for promoting oral health and preventing oral diseases.
