‘The mouth is a gateway into your body’: the fascinating, frightening links between our gums and our health
Scientists are discovering more and more associations between poor oral health and everything from heart disease to dementia. But can flossing and brushing properly guarantee a longer life?

TL;DR
- Dentistry and medicine have historically been separate fields, but links between oral health and systemic health are becoming increasingly apparent.
- Gum disease is a chronic inflammatory condition linked to cardiovascular disease, with studies suggesting up to 90% of people with heart disease also have gum disease.
- Oral bacteria can enter the bloodstream, potentially contributing to atherosclerosis, blood clots, strokes, and heart attacks.
- There is a two-way link between diabetes and oral health; gum disease can worsen blood sugar control, and high blood sugar increases vulnerability to gum disease.
- Correlations between oral health and dementia are under investigation, with gum disease associated with an increased rate of cognitive decline.
- Maintaining good oral hygiene, including brushing twice daily and flossing, is crucial for overall health.
- Diet plays a significant role, as sugar intake feeds bacteria that damage teeth and gums.
- Poor oral health can affect quality of life, confidence, and may lead to increased medication use, which can have side effects on oral health.
