Dental Floss: heart health starts in the mouth

Dental Floss — heart health starts in the mouth. Gum disease is linked to higher risk of cardiovascular disease and poor blood sugar control. Flossing removes plaque between teeth where brushes cannot reach, reducing gum inflammation. Flossing once daily, preferably before brushing, is the target supported by dental associations. This deserves attention because everyday schedules erode it long before anyone notices a symptom. The pathway runs through enzyme activity, mitochondrial output and calmer inflammatory signalling. Attach it to a habit you already have so it survives your busiest week. For most adults, keep floss next to your toothbrush and floss before you brush at night. Aim for progress you can repeat, not a perfect score.
