Periodontal pathogens are bacteria that have been shown to significantly contribute to periodontitis.

Although approximately 700 bacterial species have been identified in the oral cavity and nearly 300 species have been cultured and found to contribute to the biofilm of the periodontal pocket, there is a much smaller number of species that have been shown to be more closely related to the initial incidence and continued persistence of periodontitis, including:
