The formation of oral biofilm can be a major factor leading to periodontal disease. Harmful strains of bacteria in the oral biofilm can enter the bloodstream during the inflammatory response and travel to other areas of the body, exerting a distant systemic effect that has been connected to numerous diseases. This article reviews this link and discusses maladies associated with periodontal disease, including cardiovascular disease, chronic kidney disease, cancers, and more. A discussion of the management of oral biofilms is also included.



  • Describe the characteristics of oral biofilm and its role in causing periodontal disease.
  • Explain why patients with periodontal diseases have a higher risk of developing cardiovascular and other systemic problems.
  • Discuss ways that oral biofilms can be more effectively managed to combat periodontal disease.
