Bacteria causing periodontitis

How to prevent periodontitis? Does bacteria cause sinus infection? The mouth is colonized by 2to 3bacterial species, but only a limited number of these species participate in dental decay (caries) or periodontal disease.

Dental Decay Dental decay is due to the irreversible solubilization of tooth mineral by acid produced by certain bacteria that adhere to the tooth surface in bacterial communities known as dental plaque. Ongoing gum inflammation can cause periodontitis , eventually causing pockets to develop between your gums and teeth that fill with plaque, tartar and bacteria.

In time, these pockets become deeper, filling with more bacteria. If not treate these deep infections cause a loss of tissue and bone, and ultimately you may lose one or more teeth. Dental plaque revisited: bacteria associated with periodontal disease. Between 3-weeks after the beginning of supragingival plaque formation, a distinctive subgingival microflora predominantly made up of gram-negative, anaerobic bacteria and including some motile species, becomes established.

Persistent infection of the gum margins leads to progressive inflammation and destruction of the supporting tissues by bacterial toxins and enzymes. Extension and the hardening of plaque leads to formation of tartar beneath the gums. Having tartar within the gum pockets can lead to periodontitis.

No plaque no periodontal disease. Periodontitis is a quite common condition wherein the gums and periodontal structures that lie deeper become inflamed. It is the body’s reaction to particular bacteria that have been permitted to accumulate on the teeth. Plaque is the sticky substance that forms on your teeth soon after you have brushed.

What Causes Periodontal Disease ? In an effort to get rid of the bacteria , the cells of your immune system release substances that inflame and damage the gums, periodontal ligament or alveolar bone. Poor oral hygiene and dental plaque bacteria are considered as the main causes of gum disease. Several other factors also contribute in developing periodontal diseases. Periodontal (gum) disease is an infection of the tissues that hold your teeth in place.

Diagnosis is by inspecting the gum tissue around the teeth both visually and with a probe and X-rays looking for bone loss around the teeth. Periodontal disease is generally due to bacteria in the mouth infecting the tissue around the teeth. It's caused by bacteria that have accumulated on the teeth and gums.

This is particularly important for elderly adults in institutions such as nursing homes.

In this group, bacteria from the mouth may reach the lungs and may cause severe pneumonia. Re orange and yellow complex bacteria cause periodontitis at high, moderate or low risk, respectively. Red complex organisms (high risk): Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola.

Two main bacteria which cause localized aggressive periodontitis are A. These bacteria produce various virulence factors such as leukotoxin, Endotoxin, Bacteriocin, Collagenase and Chemotactic inhibition factors. A periodontal abscess is a collection of pus that occurs in the tooth-supporting tissues (the periodontium) as a result of bacterial infection. It usually occurs as a complication of advanced gum disease ( periodontitis ), which is caused by poor oral hygiene. The periodontal abscess causes pain that becomes worse with biting on the affected tooth. It happens when bacteria and plaque build up around the tooth, and the immune system launches a reaction.

Good oral hygiene is part of both treatment and prevention, but sometimes surgery is necessary too. Though bacterial plaque causes gum disease, tartar buildup gives bacterial plaque a place to thrive. In the first stage of gum disease (gingivitis), your gums become re swollen and bleed easily due to plaque adhering along the tooth and gumline causing inflammation around the teeth.
