How dental health affects overall health

by | May 14, 2022


The link between oral health and its impact on our overall health have been proved by numerous studies over the years. According to the WHO, ‘Most oral diseases and conditions share modifiable risk factors with the leading noncommunicable diseases (cardiovascular diseases, cancer, chronic respiratory diseases and diabetes)’. Many studies have proved that dental health overall health affects are connected, making good oral health more important than previously believed.

Gum disease and Cardiovascular health

Though the connection is not fully understood as yet, there is research to suggest that cardiovascular disease, clogged arteries and stroke might be linked with infections caused by oral bacteria. The basic premise is that the bacteria that infects gums and causes gum disease, also travel to blood vessels throughout the body where they cause blood vessel inflammation and damage, which can lead to tiny blood clots, strokes or heart attacks.

Diabetes and gum disease are also interconnected because the high blood sugar levels from diabetes causes the saliva around your teeth and under your gums to have more sugar in it. The increased sugar promotes harmful germs and plaque to grow. This leads to tooth decay, gum disease and tooth loss. Infections from untreated periodontal diseases can cause blood sugar to rise and make it harder to control diabetes.


This is a rare, life-threatening inflammation of the lining of the heart muscle and its vales, caused by a bacterial infection. While it can occur in anyone, people with heart disease are more likely to get this. If you have poor oral health and excess bacteria in the mouth it can spread through your bloodstream and attach to certain areas of your heart. If you are a patient at risk for endocarditis then it is important that you practice good oral hygiene. Brush your teeth twice a day and floss at least once a day. Use antiseptic mouthwash and be sure to be in contact with your dentist for regular check ups to avoid the possibility of developing periodontal disease.

What’s the connection between oral health and overall health?

Today there are studies that make the connection between oral health problems and general health problems because your mouth too is teeming with bacteria, usually mostly harmless bacteria. Being the entry point to your digestive and respiratory tracks, some oral bacterial can cause disease. If proper oral hygiene is not maintained bacteria can reach high levels leading to oral diseases that can then spread and cause health complications throughout the rest of your body.


Certain oral bacteria can be pulled into your lungs causing aspiration pneumonia and other respiratory diseases. Germs in the mouth multiply rapidly and can travel down to the lungs during sleep causing pneumonia. Especially risky in older people, it is essentially that good oral hygiene is maintained always to help prevent pneumonia.


Periodontitis has been associated with poor pregnancy outcomes such as preterm births and low birth weights. Pregnant women are at an increased risk of pathological dental conditions such as periodontist. This unfortunately can cause complications for both the mother and the baby, including the potential for tooth loss for the mother. When you practice good oral care it is common for the periodontal symptoms to go away after delivery. Routine dental visits while pregnant will help prevent it developing to gingivitis.

Symptoms of other health issues

Most people generally understand the importance of maintaining good oral health, but it is only recently that more people have begun to understand the connection between dental health and overall health. This is especially true for people with certain medical conditions such as heart disease, rheumatoid arthritis and kidney issues.
