What Bacteria Causes Gingivitis?


Gingivitis is primarily caused by the accumulation of plaque on teeth. Plaque is a sticky film of bacteria that forms on teeth and gums, and if it is not adequately removed through regular oral hygiene practices such as brushing and flossing, it can lead to gingivitis. The bacteria most commonly associated with gingivitis include:

  1. Porphyromonas gingivalis: This bacterium is often found in increased levels in individuals with gingivitis and periodontal disease.
  2. Prevotella intermedia: Another bacterium associated with gingivitis, it can contribute to the inflammation of the gums.
  3. Treponema denticola: This bacterium is part of the complex microbial community associated with periodontal diseases, including gingivitis.

It’s important to note that while these bacteria are commonly associated with gingivitis, the condition is often a result of a combination of various bacteria in the oral microbiome. Good oral hygiene practices, including regular brushing, flossing, and professional dental cleanings, can help prevent and manage gingivitis. If you suspect you have gingivitis, it’s advisable to consult with a dentist for proper evaluation and treatment recommendations.
