Probiotics in oral health--a review

Probiotics are dietary supplements containing potentially beneficial bacteria or yeasts. Probiotics are live microorganisms thought to be beneficial to the host organism and, when administered in adequate amounts, confer a health benefit on the host. Lactic acid bacteria and bifidobacteria are the most common types of microbes used as probiotics. Probiotics strengthen the immune system to combat allergies, stress, exposure to toxic substances and other diseases. There are reports of beneficial use in HIV infections and cancers.These products help in stimulating oral health promoting flora, and suppress the pathologic colonization and disease spread. Probiotics can be bacteria, molds and yeast, but most probiotics are bacteria. In recent years, there has been a lot of interest in the use of probiotics in maintaining good oral health and treating oral infections. Their use in premalignant and malignant oral disorders is yet to be probed.
