Sweden has a long tradition on prevention of both dental caries and periodontal disease, which has resulted in an improvement of oral health the last 50 years. Today, more or less all patients in Sweden, from early childhood to high age, get individual information by dentists and dental hygienists about: 1) oral hygiene, 2) good dietary habits and 3) use of fluoride toothpaste twice a day. In many areas of the country, population-based preventive programs are carried out at day-care centres, in schools and at home for elderly.
