The oral-systemic connection means that oral health is linked to overall health. Bacteria in the gums can enter the bloodstream and affect other organs. Gum disease is linked to chronic health conditions, like heart disease, stroke, diabetes, respiratory diseases, osteoporosis, and certain cancers. Missing teeth can cause digestive issues, including an increased risk of gastrointestinal issues. It’s also linked to cognitive decline, including conditions like Alzheimer's disease.
