A dentist has issued a warning about the significant impact certain foods can have on oral health, with potential consequences extending beyond the mouth. Recent research from the Oral Health Foundation reveals that only 15% of adults in the UK consider the effects of their diet on oral health, far fewer than those who monitor their weight (40%), heart disease risk (35%), or diabetes risk (34%).
This lack of awareness is concerning given the established connection between oral health and serious systemic diseases. While research on the exact mechanisms is ongoing, studies indicate that gum disease is linked to a higher risk of heart disease later in life.
Dr. Nigel Carter, CEO of the Oral Health Foundation, explains, “A poor diet, especially one high in sugar, promotes harmful bacteria that increase the risk of gum disease. More importantly, gum disease is not just a mouth problem—it’s associated with serious conditions such as heart disease, stroke, diabetes, and respiratory illnesses.”

He highlights that conditions such as rheumatoid arthritis, pregnancy complications, and chronic kidney disease are also tied to gum inflammation. “When gums become inflamed, it can trigger inflammation throughout the body, raising the risk for these illnesses,” Dr. Carter adds.
In response, the Oral Health Foundation urges dental professionals to offer patients comprehensive dietary advice to improve oral health. Recommendations include reducing consumption of sugary and acidic foods and drinks, which directly harm teeth and gums.
Even nutritious foods can pose challenges. For instance, citrus fruits like oranges are rich in vitamin C and provide numerous health benefits, but their high acidity can erode tooth enamel if consumed excessively.
“People often focus on sugar when watching their weight but forget that sugar harms their teeth just as much,” Dr. Carter warns. “Frequent snacking, sugary beverages, and acidic foods put additional strain on teeth and gums.”
He emphasizes the close link between oral and overall health: “Treating gum disease can aid in managing diabetes and may help lower cardiovascular risks. Your mouth is part of your whole body. Protecting your teeth means protecting your heart and overall well-being. What you eat and how you care for your mouth truly matters.”
Contrary to popular belief, tooth decay is not caused solely by junk food and sugar. Many common foods and drinks are highly acidic, which can weaken dental health. Additionally, some foods tend to stick to teeth throughout the day, fueling bacteria and impairing oral hygiene.
While it’s not necessary to eliminate healthy fruits from your diet, moderating intake and maintaining good oral care can help protect your teeth and overall health.
