Why Oral Health Matters

Dental health has a direct impact on overall health. For example, nursing home studies have shown that proper oral hygiene is more effective than antibiotics in preventing pneumonia recurrence, because harmful bacteria in the mouth can be aspirated into the lungs. Another study identified 37 common respiratory pathogens growing in dental plaque, highlighting the importance of maintaining oral cleanliness.

Periodontal disease is also linked to rheumatoid arthritis, an autoimmune condition that causes chronic joint inflammation. People with rheumatoid arthritis tend to have higher rates of gum disease and elevated levels of antibodies against periodontal bacteria, which may play a role in the disease’s progression. Similarly, type II diabetes and gum disease are closely related. Bacteria from periodontal disease release chemicals into the bloodstream that affect liver function and increase insulin resistance. Pregnant women with gum disease are at higher risk of developing gestational diabetes, and the severity of periodontal symptoms can make diabetes harder to manage.

Preventive dental care is the most effective way to protect both oral and overall health. Brushing, flossing, and regular dental visits help control plaque and calculus, keeping harmful bacteria in check. For patients with existing gum disease, more frequent dental visits are crucial to prevent progression and associated complications.

Recent research confirms that the effects of oral bacteria extend far beyond the mouth, influencing overall health and wellbeing. Maintaining good oral hygiene is not just about protecting your teeth—it is a vital part of living a healthy lifestyle. As Dr. Devarieux of the University of Minnesota School of Public Health states, “Periodontal disease is no longer just about teeth. It is about the whole body.” The traditional boundaries between dentistry, medicine, and public health are disappearing, emphasizing the critical connection between oral care and systemic health.
