disease, but it seems there's another, often-overlooked reason to keep up with our oral hygiene.CommentsNewsFiona Callingham Lifestyle writer and Steven Smith Content Editor11:39, 03 Jun

2025There are plenty of reasons to look after your mouth health(Image: undefined via Getty Images) A dentist has shed light on a commonly overlooked factor that could be contributing to your

weight struggles. She cautioned that poor dental hygiene might actually be linked to weight gain.

‌ Dr Deepa Chopra, a cosmetic and general dentist at Whites Dental, said: "Oral health may have a bigger impact on overall wellbeing than many people realise. Inflammation in the mouth could

potentially affect the way your body manages blood sugar, digestion, and appetite."

‌Gum disease Gum disease, also known as periodontitis, is one of the main offenders. "When gums are inflamed, harmful bacteria may enter the bloodstream and contribute to systemic

inflammation," Dr Chopra clarified.

"This could interfere with insulin sensitivity and how the body stores fat."

In some instances, this inflammation can make it more difficult to maintain a healthy weight, reports Surrey Live.

may encourage gum disease. The study also emphasised that overweight individuals tend to suffer from more severe forms of gum disease.

A fascinating study indicates that brushing away gum disease might also help tackle obesity.

Gut health Dr Chopra highlighted a potential connection between the bacteria in our mouths and those in our guts. Should nasty oral germs find their way into your digestive system, it could

throw off the delicate balance within the gut microbiome, which is vital for healthy digestion and metabolism.

‌ "An imbalanced gut microbiome might increase cravings for sugary, processed foods and make it harder to feel full after eating," she said. "This, over time, could contribute to overeating

or weight gain."

sensitive teeth or painful gums, they may be more likely to avoid crunchy vegetables or whole grains.

‌ "These are foods that support healthy digestion and weight – but people might instead choose softer, more processed foods that are easier to chew and often higher in calories."

Improving your gum health While regular dental hygiene is a must, considering your diet could provide extra benefits. "Brushing, flossing, and routine dental visits are essential," claimed

Dr Chopra.

"But adding anti-inflammatory foods like leafy greens, berries, and omega-3-rich fish might also help reduce inflammation in both the gums and gut."
