Abstract: The present invention is concerned with microorganisms or fragments thereof as sensorically neutral oral care agents, particularly for prevention of dental calculus, as anti-caries agents and/or anti-oral malodor agents. The invention is furthermore concerned with compositions comprising microorganisms or fragments thereof for reducing mutans Streptococci. Such compositions can be used in oral care compositions, e.g. for caries prophylaxis, or for prophylaxis of dental calculus or oral malodor.
