Can acids produced from probiotics demineralize the tooth and cause progression of caries: a critical review

Background: Probiotics are live microorganisms which that provide various health benefits to the host upon administration in adequate amounts. Lactobacilli, Propionibacterium, and Bifidobacterium common “Lactic Acid-producing bacteria (LAB)” present probiotic formulations. These release many organic acids, mainly lactic acid, acetic propionic acid into their surrounding environment. Increased concentration of these inorganic acids reduces saliva’s critical pH below 5.5, initiates demineralization. Thus, review aims critically appraise existing evidence on this emerging clinical perspective double edged nature bacteria, explain as how supplements increase risk tooth decay. Results: Lactobacilli were associated with rampant caries preschool children progression caries. All probiotics acidogenic they decreased saliva, demineralized eroded enamel. also extracellular polysaccharides help essential elements like calcium phosphorous from enamel surface. The acid-producing efficiency is increased when combined supragingival plaque. Low was attributed interaction other microorganisms. Conclusion: Acids can lower oral cavity five, play a role demineralization
