Understanding the Consequences of Poor Oral Health on Your Health

Our mouth is the primary entryway into the body; so it goes without saying that poor oral hygiene can lead to adverse health consequences for the body.

Bacteria from your mouth can make their way in your bloodstream and cause infectious diseases, leading to a variety of health conditions.

Here are the potential health consequences of poor oral health that you should know:

Cardiovascular Disease

Poor oral health is associated with an increased risk of developing heart diseases like a heart attack or stroke.

According to a study published by Harvard Medical School, people who have poor oral health have higher rates of cardiovascular problems than people with good oral hygiene.

For instance, gum inflammation can lead to periodontal disease, which can enter into the bloodstream and result in plaque buildup in the arteries.

It can also lead to atherosclerosis (clogged arteries), which can increase the risk of having a heart attack.

Poor oral hygiene also heightens the risk of Endocarditis, an infection of the inner lining of the heart.

Severe periodontal disease can increase blood sugar, which puts people with diabetes at increased risk for diabetic complications.

Gum disease can be more severe for diabetic people and take longer to heal. Gingival pockets that are deeper than 4 mm are more common in people with diabetes than those without.

Therefore, doctors recommend people with diabetes to cut down sugar and take care of their oral hygiene to avoid complications.

Rheumatoid Arthritis

The presence of periodontal disease, like chronic periodontitis and gingivitis, can result in Rheumatoid Arthritis, a painful and debilitating inflammatory disease.

Johns Hopkins study from 2015 found that out of 70% of RA patients had at least moderate gum disease. Poor oral health can play a part in initiating joint pain symptoms or exacerbating them.

Another study from the following year showed that chronic gum inflammation can activate an inflammatory response, which may spread throughout the body, triggering symptoms of rheumatoid arthritis.


The studies done by various authors show that compromised oral health may prove a risk factor for carcinogenesis (the initiation of cancer formation).

Tobacco use, like chewing tobacco and smoking, is the most significant risk factor for oral cancer. The affected areas may include gums, tongue, lips, and floor of the mouth.

Other types of cancer have also been linked to gum disease, including liver, colon, rectum and pancreatic cancer.

Moreover, people with missing teeth may consume softer and potentially less nutritious foods, which can also increase the risk of liver cancer.

Respiratory Infections

Cavities and gum disease can cause bacterial infection, which can spread to the lung and harm them or worsen the chronic inflammation in lung diseases such as asthma.

Therefore, poor periodontal health is a risk factor for respiratory disease. Cross-sectional study findings also support an association between respiratory and periodontal disease.

Bacteria that travel through saliva can modify the respiratory epithelium and promote colonization by respiratory pathogens.

Elderly adults with poor oral hygiene are more prone to respiratory infections as they swallow a more dysbiotic microbiota formed on the tongue.

Kidney Disease

Dental cavities and gum diseases are chronic bacterial infections that can contribute to kidney disease, which can be fatal, if not treated timely.

Studies have shown that periodontitis can lead to systemic inflammation, hindering glycemic control and increasing the risk of chronic kidney disease (CKD).

People with kidney disease have weakened immune systems, which makes them more vulnerable to bacterial infections.

Therefore, bacteria in the mouth of people with kidney disease are more likely to cause infection, leading to periodontal disease and other oral health problems.


Research exploring the relationship between oral health and dementia has suggested that “poor oral hygiene is associated with dementia, and more so amongst people in advanced stages of the disease”.

Moreover, oral infections like gingivitis when left untreated spreads to the nerve channels can destroy nerve cells essential for memory.

Bacteria released from inflamed gums can kill brain cells and contribute to symptoms, including confusion and failing memory.

A study conducted by UCLan also shows the connection between poor dental health and dementia.

How to improve your oral health?

See your dentist at least twice a year to make sure your oral health is in check. A dentist will look for cavities, spot potential issues, and offer treatment solutions.

It’s important to understand that your daily habits are crucial to your overall oral health. Make sure you follow an effective dental care routine to keep your oral health in check.

Never go to bed without brushing your teeth. Ideally, you should brush your teeth twice a day. Additionally, following a proper brushing technique is essential to remove plaque and avoid gum disease.

Most oral health problems stem from calculus and plaque buildup, mainly due to improper cleaning technique, which is worse than not brushing at all.

Moreover, mechanical plaque removal with a manual toothbrush isn’t very effective in suppressing the bacteria that cause plaque and gum disease.

Therefore, you should consider switching to an electric toothbrush that can provide you with a longer-lasting, deeper cleaning to keep your mouth clean and healthy.
