Infected Teeth: Stroke Risk And Prevention

Oral health is linked to a person's general health, and poor oral health is associated with an increased risk of stroke. Dental infections resulting from poor oral hygiene are among the most common chronic bacterial infections, and can spread to nearby bone and soft tissues.

Gingivitis, periodontitis, and dental caries are the most common chronic orodental diseases in humans. Gingivitis is an inflammation of the gums triggered by bacterial microorganisms, which can progress to periodontitis if left untreated. Periodontitis is caused by local infections with periodontal pathogens, which can lead to systemic reactions such as inflammation and immunological reactions.

The presence of oral bacteria in the brain has been found in patients who have had a stroke. A study found that 84% of participants had bacterial DNA in their blood clot, with 59 of them having a strain of streptococci commonly found in the mouth. Associations between all forms of gum disease and stroke have been reported, with severe periodontitis leading to tooth decay, bone loss, and even tooth loss.

Tooth loss has also been linked to an increased risk of stroke, with one study finding that individuals with more missing teeth had usually experienced more strokes. Tooth loss was also found to be a predictor of silent strokes, which are strokes that people don't know they've had because they don't cause obvious handicaps. However, the build-up of silent strokes can cause disabling problems such as dementia over time.

Inflammation and infection, which characterise gum disease, seem to be the most significant link to the increased risk of having a stroke. Ischemic strokes, which are caused by a blockage in a blood vessel in the brain, are the type of stroke most commonly associated with dental problems.

Practising good oral health habits can help reduce the risk of developing other systemic health issues, including strokes.

Gum disease and tooth loss are associated with an increased risk of stroke

Several studies have found a link between gum disease and stroke. For example, a study from Germany identified an increased risk for an ischemic stroke in patients with severe periodontitis. Another study from Greece confirmed that patients with periodontitis are associated with a higher risk of stroke. Additionally, a recent meta-analysis study found that the risk of ischemic stroke is 2.8 times higher in patients with periodontal conditions than those without.

Tooth loss has also been found to be associated with an increased risk of stroke. A study from Korea found that tooth loss was a predictor of silent strokes, which are strokes that people don't know they had because they don't cause obvious handicaps. Another study from the United States found that the number of missing teeth was an independent determinant of the self-reported history of stroke.

The exact nature of the association between gum disease, tooth loss, and stroke is still unclear and requires further research. However, it is believed that the inflammation and infection caused by gum disease and tooth loss may increase the risk of stroke by making the blood more likely to clot.

Oral bacteria can enter the bloodstream and cause inflammation and infection, which are risk factors for stroke

Oral health is linked to overall health, and poor oral hygiene can have consequences beyond the mouth. Research has shown that dental problems can lead to stroke. Periodontal disease (gum disease) is associated with strokes, with severe periodontitis leading to tooth decay, bone loss, and tooth loss. Tooth loss, in particular, is an independent determinant of self-reported stroke history.

Dental problems such as gingivitis, periodontitis, and tooth loss are all associated with inflammation and sometimes infection. Infections increase the risk of stroke, possibly due to the body's inflammatory immune response. Inflammation and infection can make the blood more likely to clot, causing a stroke.

The mouth contains harmful oral bacteria, such as P. gingivalis, which has been linked to problems within the carotid arteries. Harmful oral bacteria may increase C-reactive inflammatory protein in the body, a risk factor for strokes and heart disease.

Gingivitis is a common condition characterised by swollen, tender, and bleeding gums. If left untreated, gingivitis can progress to periodontal disease, impacting over 47% of Americans. Associations between all forms of gum disease and stroke have been reported, with some studies suggesting a link between tooth loss and a greater risk of stroke.

Dental problems have been mainly linked to the development of ischemic strokes, which are caused by a disruption of blood supply to the brain due to a blood clot.

Dental problems can lead to an increase in C-reactive inflammatory protein, a risk factor for strokes

Poor oral health has been linked to an increased risk of stroke. Periodontal diseases and tooth loss are two common oral health measures. Dental infections caused by poor oral hygiene are among the most common chronic bacterial illnesses, often affecting those who avoid or delay going to the dentist.

Research studies have shown that varying degrees of periodontal disease (gum disease) are associated with strokes. Mild gum disease, which causes inflammation of the gums, is called gingivitis, while more serious gum disease that causes the actual destruction of the gums is called periodontitis. Severe periodontitis can lead to tooth decay and even tooth loss. All three of these types of gum disease are associated with a stroke.

Dental problems such as gingivitis, periodontitis, and tooth loss are all associated with inflammation, and sometimes with an infection. Infections have been shown to increase the risk of stroke, possibly due to the body's inflammatory immune response to infections. Sometimes, inflammation and infection can make the blood more likely to clot, causing a stroke.

C-reactive protein (CRP) is a pentameric plasma protein that is produced in response to many forms of injury. It is a pattern recognition molecule that is extremely sensitive and non-specific acute-phase marker for inflammation. CRP is regulated by cytokines like interleukin-6 (IL-6), interleukin-1β (IL-1β) and tumour necrosis factor-α (TNF-α). CRP levels increase to hundreds of μg/ml within hours following infection.

Many epidemiological studies have shown that serum CRP levels were elevated in patients with chronic periodontitis. CRP elevation is a part of the acute phase response to acute and chronic inflammation. CRP levels have an association with smoking, obesity, triglycerides, diabetes, and periodontal disease.

A study by Alhadainy et al. found that the number of missing teeth was an independent determinant of the self-reported history of stroke. Another study by Ajwani et al. concluded that among the edentulous, chronic infections like denture-related mucosal lesions are important determinants of elevated CRP, comparable to periodontal disease in the dentate.

A pilot study by Asikainen et al. showed that treating adult periodontitis decreases CRP levels, as measured with a sensitive assay. The decrease in CRP levels occurred mostly in individuals with elevated CRP levels at baseline. Treating periodontitis lowers CRP levels in these individuals and may thus decrease their risk of coronary heart disease.

Poor oral health is linked to other health issues like heart disease, diabetes, and Alzheimer's disease

Poor oral health is associated with a range of health issues, including heart disease, diabetes, and Alzheimer's disease.

Heart Disease

Several studies have found a link between poor oral health and an increased risk of heart disease. For example, a study from Tabriz University of Medical Sciences in Iran found that participants with periodontitis had a stronger correlation with stroke than those with coronary artery disease. Other studies have also shown that poor oral hygiene can lead to periodontal diseases, which, in turn, are associated with hypertension and heart disease.

Diabetes

Poor oral hygiene can contribute to tooth decay, dental caries, and severe oral diseases such as periodontitis and gingivitis. Research has found a connection between these oral health issues and diabetes. For instance, a study from Qatar found that the number of missing teeth was an independent determinant of self-reported history of stroke, with those who had more missing teeth being more likely to report a history of stroke.

Alzheimer's Disease

Emerging evidence suggests a link between poor oral health and Alzheimer's disease. A recent study using the TriNetX database found that poor oral health was associated with a more than two-fold increase in the risk of Alzheimer's disease, independent of age, gender, and common laboratory measures. Furthermore, oral diseases related to tooth loss were found to be the most significant risk factor for Alzheimer's disease.

Maintaining good oral hygiene can help reduce the risk of developing systemic health issues, including strokes

Oral bacteria can enter the bloodstream and cause infections if left untreated. Gum disease, or gingivitis, is a common condition characterised by swollen, tender, and bleeding gums. If left untreated, gingivitis can progress to a more severe form of gum disease called periodontal disease, which can result in tooth decay, bone loss, and even tooth loss. According to the Centers for Disease Control and Prevention, over 47% of Americans suffer from periodontal disease.

The harmful bacteria associated with gum disease, such as P. gingivalis, have been linked to problems within the carotid arteries and an increase in C-reactive inflammatory protein, a risk factor for strokes and heart disease. Associations between all forms of gum disease and stroke have been reported, and some studies suggest that tooth loss may also increase the risk of stroke.

Inflammation and infection, which characterise gum disease, seem to be the most significant link to the increased risk of stroke, particularly ischemic strokes, which are caused by blood clots disrupting the blood supply to the brain.

Practising good oral hygiene, such as brushing twice a day and flossing once a day, can help reduce the risk of developing systemic health issues, including strokes. Regular dental visits are also key to preventing and managing oral health issues.
