Bacterial plaque

Dental plaque is characterized as the community of microorganisms found on the surface of a tooth as a biofilm, embedded in a polymer matrix of host and microorganism origin. The fact that biofilms are less susceptible to antimicrobial agents and microbial communities may even exhibit pathogenic synergism (improved pathogenicity) is clinically relevant.
