Include dental coverage in health insurance, after all, teeth ARE bones that are exposed. Our oral cavity is still a part of the human body, so it is nonsensical to have it separated from health care and maintenance.
Teach real health care and nutrition in schools starting in elementary school. Also, teach more advanced health and nutrition to adults via printed lessons that children take home.
Also, many products, ie mouthwash and seed oils and highly processed foods, have detrimental effects on health, but there are no warnings in television advertisements or elsewhere.
