S. mutans is the best established, converting dietary sucrose to extracellular glucans that anchor the plaque and to lactic acid that demineralises enamel; S. sanguis is an early coloniser of the tooth surface and contributes to the same process. S. pyogenes is a pharyngeal and skin pathogen with no part in caries.
