Oral health is often neglected, but it can have a significant impact on overall health. Poor oral hygiene can lead to the growth of bacteria that can cause various health problems, ranging from gum diseases to heart diseases.

Recent studies have discovered a link between oral bacteria and several other conditions. In this article, we will discuss the diseases linked to oral bacteria.

Gingivitis and Periodontitis

Gingivitis is a mild form of gum disease that causes redness, swelling, and bleeding of the gums. It is caused by the accumulation of plaque on teeth and gum line that harbors bacteria which produce toxins.

If left untreated, gingivitis can progress into periodontitis, which is a severe form of gum disease that destroys the tissues and bone that support teeth. Studies have shown a strong correlation between the prevalence of oral bacteria and gum diseases.

The bacteria involved in gum diseases are predominantly gram-negative anaerobes such as Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia.

Cardiovascular Diseases

Oral bacteria can enter the bloodstream through the gums, where they can travel to other parts of the body and cause inflammation. The inflammation caused by oral bacteria has been linked to an increased risk of heart disease.

The bacteria responsible for gum diseases can also contribute to the formation of plaque in the arteries, which can lead to atherosclerosis or hardening of the arteries. Atherosclerosis can restrict blood flow to the heart, which can result in chest pains or a heart attack. Poor oral health has also been associated with an increased risk of stroke.

Respiratory Diseases

The spread of oral bacteria through the bloodstream can also cause respiratory infections. The bacteria can travel to the lungs and cause infections such as pneumonia, bronchitis, and chronic obstructive pulmonary disease (COPD).

Poor oral hygiene can also result in the growth of anaerobic bacteria that can produce sulfur compounds, which can cause bad breath or halitosis.

Dementia

Studies have shown that older adults who have poor dental health or suffer from gum disease are more likely to develop dementia and Alzheimer’s disease.

The bacteria responsible for gum diseases can travel to the brain through the bloodstream and cause brain inflammation or damage. Chronic inflammation has been linked to neurodegenerative diseases and cognitive decline.

Preterm Birth and Low Birth Weight

Oral bacteria can also affect pregnancy outcomes. Pregnant women with gum disease or poor oral health are more likely to give birth prematurely or to babies with low birth weight.

This is because the infection and inflammation caused by oral bacteria can release prostaglandins and cytokines, which can induce premature labor or inhibit fetal growth. Furthermore, the bacteria can also travel to the uterus and cause infections or complications during pregnancy.

Diabetes

Diabetes and gum disease are often interrelated. People with diabetes are more likely to develop gum disease, and gum disease can make it harder to control blood sugar levels.

Some studies suggest that oral bacteria can also cause insulin resistance and increase inflammation in the body, which can aggravate diabetes symptoms.

Chronic Kidney Disease

Oral bacteria have also been linked to the development of chronic kidney disease. A study conducted on 6,659 participants found that those with gum disease had a higher risk of developing chronic kidney disease.

The researchers speculate that the inflammation caused by oral bacteria can impair kidney function and increase the risk of kidney disease.

Rheumatoid Arthritis

Rheumatoid arthritis is a chronic autoimmune disease that causes joint inflammation and damage. Recent studies have discovered a link between oral bacteria and the development of rheumatoid arthritis.

The bacteria involved in gum diseases can produce enzymes that can activate immune cells and cause joint inflammation. Researchers are still investigating the relationship between oral bacteria and rheumatoid arthritis and whether improved oral hygiene can prevent or reduce the severity of the condition.

Cancer

Several types of cancer have been linked to poor oral health, including oral cancer, pancreatic cancer, and esophageal cancer.

The bacteria involved in gum disease and oral infections can produce carcinogenic toxins that can damage the DNA and promote the growth of cancer cells. Some studies suggest that the inflammation caused by oral bacteria can also contribute to cancer development.

Conclusion

Poor oral hygiene can have far-reaching consequences for our health. The bacteria that reside in our mouth and gums can travel throughout the body and cause a range of health problems, from gum diseases to chronic illnesses.

By practicing good oral hygiene habits, we can reduce the risk of oral bacteria-related diseases and improve our overall health.
