Abstract
Because S. Sanguis is the first colonizer of newly cleaned teeth and because other bacteria then attach to it, the formation of dental plaque is reduced on newly cleaned teeth by introducing into the mouth bacteriophages which are parasitic to S. Sanguis. Because S. Sanguis is the means of attachment of plaque forming bacterial colonies to tooth surfaces and forms 10-15% of the organisms in plaque, destruction of S. Sanguis by introduction of its parasitic bacteriophages will remove plaque from teeth surfaces. And removal of plaque containing acid forming bacteria and other harmful bacteria reduces the incidence of dental caries and other disease.
