Medical experts are increasingly focusing on the relationship between oral health and a range of systemic diseases. Dr Graham Lloyd-Jones, a consultant radiologist at Salisbury NHS Foundation Trust, is among those researching the impact of oral bacteria on conditions that affect the entire body. He began his work during the COVID-19 pandemic and is currently writing a book summarizing his findings.
According to Dr Lloyd-Jones, there appears to be a much stronger link between poor oral health—specifically gum disease—and serious illnesses than many previously believed. His research on COVID-19 highlighted how bacteria from the mouth could pass through damaged gums directly into the lungs and bloodstream. He noted that the risk factors for severe cases of COVID-19 and gum disease often overlap, which led him and other dental specialists to suggest that gum disease could be a major risk factor for more severe COVID-19 outcomes.
Further studies led Dr Lloyd-Jones to explore connections between gum disease and chronic illnesses such as diabetes, Alzheimer’s disease, heart disease, and rheumatoid arthritis. He explained that harmful oral bacteria, particularly Porphyromonas gingivalis, can remain active in gum tissues for years, causing ongoing inflammation that may affect a person’s overall health. These bacteria are able to evade immune defenses and create long-lasting infections.
The research also touched on the potential link between oral health and complications during pregnancy. Dr Lloyd-Jones found that similar bacteria might be present in cases of lung cancer, surprising many of his medical colleagues. This evidence suggests oral health could play a much bigger role in systemic diseases than has previously been understood.
Increasing awareness of these links could mean a greater emphasis on oral hygiene in medical practice. Dr Lloyd-Jones continues to promote better oral health across the UK and urges both health professionals and the public to consider its importance for preventing chronic disease.
