Over half the adult population in the UK and US have gum disease. Typical treatments include mouthwash and in severe cases, antibiotics. These treatments have side effects, such as dry mouth, the development of antimicrobial resistance and increased blood pressure.

But research has indicated that a molecule called nitrate, which is found in leafy green vegetables, has fewer side effects and offers greater benefits for oral health. And it could be used as a natural alternative for treating oral disease.

Inadequate brushing and flossing leads to the build up of dental plaque, a sticky layer of bacteria, on the surface of teeth and gums. Plaque causes tooth decay and gum disease. Sugary and acidic foods, dry mouth, and smoking can also contribute to bad breath, tooth decay, and gum infections.

The two main types of gum disease are gingivitis and periodontitis. Gingivitis causes redness, swelling and bleeding of the gums. Periodontitis is a more advanced form of gum disease, causing damage to the soft tissues and bones supporting the teeth.

Periodontal disease can therefore, lead to tooth loss and, when bacteria from the mouth enter the bloodstream, can also contribute to the development of systemic disorders such as cardiovascular disease, dementia, diabetes and rheumatoid arthritis.

Leafy greens may be the key to better oral health. Research suggests that nitrate-rich vegetables like lettuce and spinach could hold the key to improving oral health. These findings could revolutionize the way we approach oral care, potentially offering a natural and effective alternative to traditional treatments.

With over half of the adult population in the UK and US suffering from gum disease, the potential benefits of incorporating more leafy greens into our diets are significant. By promoting oral health through dietary means, individuals may be able to reduce their reliance on treatments with potential side effects, and ultimately improve their overall oral health and well-being.
