Pathogenic bacteria in the mouth

Pathogenic bacteria in the mouth refers to a diverse group of bacterial species present in dental plaque and oral biofilms that are capable of causing disease. Major examples include Streptococcus mutans (involved in dental caries), Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola (key pathogens in periodontitis, often called the “red complex”)[4][6][8]. These bacteria can form complex biofilms, evade host immune responses, and produce toxins and metabolic products that lead to tissue destruction, inflammation, and increased risk for systemic conditions[4][6][8]. Treatment typically involves antibiotics, antiseptics, improved oral hygiene, and sometimes specific antimicrobials targeting key pathogens[5][6][8][9]. Note: - There is no single canonical molecule, receptor, or gene corresponding to "Pathogenic bacteria in the mouth"; rather, the term encompasses hundreds of distinct bacterial species from multiple phyla (such as Firmicutes, Proteobacteria, Bacteroidetes, Actinobacteria, Spirochaetes)[2][9]. - For structured target information, individual species (e.g., Streptococcus mutans, Porphyromonas gingivalis) should be the entries rather than the broad "pathogenic bacteria in the mouth" category.
