Everyone knows how important it is to brush their teeth twice daily and floss regularly. You understand that by taking these measures, you’re preventing tooth decay and gum disease. However, did you know that proper dental hygiene isn’t just crucial for your oral health but is also essential for your physical health? This article will explore how poor oral hygiene can lead to serious physical issues and how proper dental care can help prevent them.

The Link Between Oral Health and Physical Health

Numerous scientific studies have established the link between oral and physical health. Poor oral hygiene habits can result in various ailments, including heart disease, stroke, diabetes, dementia, cancer, premature birth, and more. Here we take an in-depth look at some of these connections:

Heart Disease

Poor oral health has been linked to an increased risk of heart disease. Bacteria from plaque buildup on the teeth can enter the bloodstream via the gums and cause inflammation in the arteries. This can increase the risk of clogged arteries, stroke, and heart attack.


Studies have found that people with diabetes are more likely to suffer from gum disease than those without diabetes. Furthermore, the severity of gum disease seems to be linked to how well-controlled a person’s blood sugar levels are. This is why if you’re diabetic, you need to take extra care regarding your oral health.

Evidence suggests poor oral health may increase a person’s risk of developing dementia as they age. Bacteria from gum disease has been found in the brains of some individuals with dementia, suggesting a link between poor oral hygiene and a decline in cognitive function.


Poor oral health has been linked to certain types of cancer, most notably head and neck cancers. This is believed to be due to bacteria in the mouth, which can spread throughout the body and increase the risk of developing cancerous cells.

Premature Birth

Studies have shown that pregnant women with poorly maintained teeth are more likely to give birth prematurely than those who take good care of their teeth. Poor dental health during pregnancy has also been associated with an increased risk of low birth weight and developmental problems in babies.
