Probiotics are usually defined as live bacterial cultures, which contain lactic acid bacteria such as lactobacillus and bifidobacterium. They can be taken as oral supplements or added to food. During the last few years, several authors have suggested that probiotic bacteria originally planned for gut health could also be beneficial to oral health. The aim of this review is to examine potential mechanisms of probiotic bacteria in the oral cavity and to summarize observed effects of probiotics with respect to oral health.
