What bacteria causes periodontitis

Periodontitis is a serious gum infection that can damage the soft tissue and bone that supports the teeth. It is caused by a build-up of bacteria in the mouth that triggers an inflammatory response. There are several types of bacteria that can cause periodontitis, including:

1. Porphyromonas gingivalis – This bacteria is one of the most common causes of periodontitis. It is a gram-negative bacterium that can invade the gums and cause damage to the surrounding tissue.
2. Tannerella forsythia – This bacteria is another common cause of periodontitis. It is also a gram-negative bacterium that can invade the gums and cause damage to the surrounding tissue.
3. Treponema denticola – This bacteria is a spirochete that can penetrate deep into the gum tissue and cause inflammation and damage to the bone.
4. Aggregatibacter actinomycetemcomitans – This bacteria is a gram-negative bacterium that is commonly found in people with severe periodontitis. It can invade the gums and cause damage to the surrounding tissue.
5. Fusobacterium nucleatum – This bacteria is a gram-negative bacterium that can colonize the gums and cause inflammation and damage to the surrounding tissue.

These bacteria are commonly found in the mouth, but they can become problematic when they accumulate and form plaque on the teeth and gumline. Plaque can eventually harden into tartar, which can be difficult to remove without professional dental treatment. As the bacteria continue to grow and multiply, they can trigger an immune response in the body that can lead to inflammation and damage to the surrounding tissue.

Preventing periodontitis involves good oral hygiene habits, such as brushing and flossing regularly and visiting a dental professional for regular cleanings and check-ups. It’s important to be aware of the potential signs and symptoms of periodontitis, which may include swollen or bleeding gums, bad breath, and loose or shifting teeth. If you suspect you may have periodontitis, it’s important to seek professional treatment as soon as possible to prevent further damage to your teeth and gums.
