This review presents current knowledge on probiotic bacteriotherapy from an oral health perspective. Recent experimental studies and results from randomized controlled trials have shown that certain gut bacteria, in particular species of Lactobacillus and Bifidobacterium, may provide beneficial effects in the oral cavity by inhibiting cariogenic streptococci and Candida sp. Therefore, the concept of probiotic therapy is interesting and pertinent, and merits further research in the fields of oral medicine and dentistry.
