  • The Effective Use of Fluorides in Public Health
    The effective use of fluorides in public health Sheila Jones,1 Brian A. Burt,2 Poul Erik Petersen,3 & Michael A. Lennon4 Abstract Dental caries remain a public health problem for many developing countries and for underprivileged populations in developed countries. This paper outlines the historical development of public health approaches to the use of fluoride and comments on their effectiveness. Early research and development was concerned with waterborne fluorides, both naturally occurring and added, and their effects on the prevalence and incidence of dental caries and dental fluorosis. In the latter half of the 20th century, the focus of research was on fluoride toothpastes and mouth rinses. More recently, systematic reviews summarizing these extensive databases have indicated that water fluoridation and fluoride toothpastes both substantially reduce the prevalence and incidence of dental caries. We present four case studies that illustrate the use of fluoride in modern public health practice, focusing on: recent water fluoridation schemes in California, USA; salt fluoridation in Jamaica; milk fluoridation in Chile; and the development of “affordable” fluoride toothpastes in Indonesia. Common themes are the concern to reduce demands for compliance with fluoride regimes that rely upon action by individuals and their families, and the issue of cost. We recommend that a community should use no more than one systemic fluoride (i.e. water or salt or milk fluoridation) combined with the use of fluoride toothpastes, and that the prevalence of dental fluorosis should be monitored in order to detect increases in or higher-than-acceptable levels.

  • Water Fluoridation: a Community Toolkit
    Water Fluoridation: A Community Toolkit Community Water Fluoridation Toolkit INTRODUCTION Oral health is important throughout a person’s life. The Missouri Coalition for Oral Health supports water fluoridation because it is one of the most cost-effective strategies for communities to improve the oral health of their residents. Fluoride exists naturally in virtually all water supplies. “Fluoridation” is simply adjusting fluoride to the optimal level that protects teeth from decay. Studies show that fluoridation reduces tooth decay and benefits people of all ages and income groups. Two studies released in 2010 strengthened the already substantial evidence that fluoridated water prevents cavities. As an oral health advocate, the Coalition’s “Water Fluoridation: A Community Toolkit” is your resource on the health benefits, cost savings and media outreach on fluoridation. The Coalition encourages you to use the toolkit as you talk with friends, colleagues and opinion leaders within your community about community water fluoridation. For more information, visit us at www.oralhealthmissouri.org or 573.635.5570. This toolkit is an adaptation of a document originally published by the Michigan Oral Health Coalition. The Missouri Coalition for Oral Health gratefully acknowledges their generosity in sharing these valuable materials. Funding for this project was provided in part by the Health Care Foundation of Greater Kansas City, the Missouri Foundation for Health, and the REACH Healthcare Foundation. www.oralhealthmissouri.org Community Water Fluoridation

  • Water Fluoridation: Questions and Answers
    WATER FLUORIDATION QUESTIONS & ANSWERS April 2012 1 Acknowledgement I would like to acknowledge and extend my heartfelt gratitude to the many individuals who have supported this project and made valuable contributions to the development of this report. 2 Preamble Dental decay is the most common chronic disease in North America, affecting over 96 per cent of Canadians. The use of water fluoridation for the prevention of tooth decay has been used for over 60 years and is endorsed by over 90 national and international government and health organizations, including Health Canada, the Canadian Public Health Association, the Canadian Dental Association, the Canadian Medical Association and the World Health Organization. Since its inception, extensive research has consistently demonstrated the safety and effectiveness of fluorides in the prevention of dental caries. In addition, there has been continual monitoring of this scientific literature by the world’s major national and international health organizations, committees of experts and special councils of governments. To date the results of these reviews reaffirm that water fluoridation, at the recommended level, is a safe and effective means of reducing dental decay and does not pose a risk for health problems. This document has been prepared for public health professionals and councils, including those of the medical and dental fields, to address common questions about the safety and efficacy of water fluoridation. A number of these questions address myths and misconceptions advanced by opponents of water fluoridation. The answers are based on generally accepted, peer-reviewed, scientific literature, including recent publications from the Public Health Agency of Canada and Health Canada.

After discussion between the parties, it was agreed that the Office of the PMCSA and the RSNZ would establish a panel to undertake a review. This review would adhere strictly to the scientific issues of safety and efficacy (or otherwise), but take into account the various concerns that have been raised in the public domain about the science and safety of fluoride. It would not consider the ethical and philosophical issues that have surrounded fluoridation and influenced legal proceedings lately. The Prime Minister gave his consent for the Office of the PMCSA to be involved and funding was provided by Councils through your office and by the Ministry of Health.

  • Fluoridation Faqs
    Frequently Asked Questions on Community Water Fluoridation What is fluoride? Fluoride is nature’s cavity fighter with small amounts present in all water sources such as lakes, rivers and wells. Community water fluoridation is simply the addition of fluoride to water to a level that helps prevent tooth decay. How does fluoride protect teeth? While teeth are forming under the gums, drinking water and other beverages with fluoride helps strengthen tooth enamel making it stronger and more resistant to cavities. This provides what is called a “systemic” benefit. After teeth erupt, fluoride helps rebuild (remineralize) weakened tooth enamel and reverse early signs of tooth decay. When you brush your teeth with fluoride toothpaste, or use other fluoride dental products, you are providing a “topical” benefit because the fluoride is applied to the surface of your teeth. In addition, the fluoride you take in from drinking water and other beverages continues to provide a topical benefit because it becomes part of your saliva, constantly bathing the teeth and helping to rebuild weakened tooth enamel. The maximum reduction in tooth decay occurs when fluoride is available systemically and topically. Studies show that community water fluoridation prevents at least 25 percent of tooth decay in children and adults throughout the lifespan. What is water fluoridation? All water contains some naturally occurring fluoride, but often at levels too low to prevent tooth decay. Community water fluoridation is simply the addition of fluoride to water to a level that helps prevent cavities. As of 2014, 74.4 percent of the U.S. population on public water systems, or a total of 211.4 million people, had access to fluoridated water at recommended levels.

  • Community Water Fluoridation: a Public Health Imperative
    Community Water Fluoridation: A Public Health Imperative Fluoridated water is considered one of the 10 greatest public health achievements of the 20th century. Just the facts: • An estimated 72 million, or almost 30% of all people in the United States, are served by non-fluoridated public water systems. • Community water fluoridation reduces tooth decay by an estimated 25% over a lifetime. • Nearly one in four children living in low-income families has untreated tooth decay; tooth decay remains the most common chronic disease of childhood. • On average, people that live in fluoridated water communities have 25% fewer trips to the dentist than people in communities with non-fluoridated water. • Frequent exposure to the optimal fluoride concentration in water is an effective strategy to reduce the risk of tooth decay at the population level because it does not require any individual behavioral change. The protective effects of community water fluoridation are experienced across all age, racial, ethnic and socioeconomic groups, but benefit Fluoridated water reduces vulnerable populations the most. health care costs. Consider this: • Community water fluoridation has been shown to save money for families and the health care system. • For every dollar spent on community water fluoridation, $38 is saved in health care costs. $1 $38 • Many vulnerable and underserved populations face substantial barriers to accessing dental care, and community water fluoridation ensures adequate fluoride exposure regardless of access For every dollar spent on community water to a dentist, insurance coverage or the ability to fluoridation, $38 is saved in health care costs. pay for dental care.

  • Water Fluoridation Myths and Facts
    Water Fluoridation Myths and Facts MYTH: “Fluoride doesn’t belong in drinking water.” FACT: Fluoride occurs naturally in water, though rarely at the optimal level to protect teeth. It’s already there. Fluoride exists naturally in virtually all water supplies and even in various brands of bottled water. If the people making this statement truly believed it, they would no longer drink water or grape juice — or eat shellfish, meat, cheese or other foods that contain trace levels of fluoride. What’s at issue is the amount of fluoride in water. There are proven benefits for public health that come from having the optimal level of fluoride in the water — just enough to protect our teeth. In 2011, federal health officials offered a new recommended optimal level for water fluoridation: 0.7 parts per million. That’s our goal: getting just enough to help all of us keep our teeth longer. MYTH: “Adding fluoride is like forcing people to take medication” FACT: Numerous scientific studies and reviews have recognized fluoride as an important nutrient for strong, healthy teeth. Fluoride is not a medication. It is a mineral, and when present at the right level, fluoride in drinking water has two beneficial effects: preventing tooth decay and contributing to healthy bones. There are several examples of how everyday products are fortified to enhance the health of Americans — iodine is added to salt, folic acid is added to breads and cereals, and Vitamin D is added to milk. MYTH: “Our city council can save money by ending fluoridation of our water system.” FACT: Fluoridation is one of the most cost-effective health strategies ever devised.
