The Portuguese Union for Oral Prevention (UPPO) is a nationwide, nonprofit private association dedicated to promoting oral health and prevention in Portugal. It serves as a platform for discussion and reflection on oral health, seeking to strengthen the knowledge and skills of health professionals, educators and those responsible for education. UPPO also develops proposals and recommendations for public authorities and the wider public to support better oral health and preventive care.

The association shares articles, opinions, professional news and updates about its activities, and invites visitors to take part in surveys on access to healthcare and suggest ways to improve its services. Health professionals and other interested individuals or organisations can apply to become members, provide professional information and express interest in joining oral health promotion initiatives. The website also publishes announcements, including dental employment opportunities and listings for clinical materials and equipment. Visitors can contact UPPO, subscribe to its newsletter and explore resources and links to related professional, educational and health organisations.
