2 Community Water Fluoridation: Where it started How it works Building a village to support it

3 Fluoride & Fluoridation: 400 mile view Grassroots view

4 Fluoride is Naturally Occurring 13 th most abundant mineral in the earth s crust Surface water (rivers) -- typically low concentrations, 0.2 mg/l (ppm) or less Groundwater (wells) --higher concentrations, 0.1 mg/l to over 5.0 mg/l Ocean water is typically 0.8 to 1.4 mg/l

6 How Did We Discover the Scientific Benefits of /.FDZ```Q Fluoride on Reducing Decay?

7 History of Fluoride s Benefits Frederick S. McKay 1901 established practice in Colorado Springs, CO Colorado Brown Stain Only life-long residents (or those who had moved there as infants) had stain 1908 began to investigate extent of condition in surrounding areas Key Observation: very few cavities in this population

8 H. V. Churchill used a newly available method of spectrographic analysis that identified high concentrations of fluoride (13.7ppm) in the water of a community in Arkansas with high rates of mottled enamel 1931 McKay contacted Churchill and sent him water samples. Fluoride was discovered in each sample that McKay sent for analysis (2.0ppm to 12.0 ppm) It was now known what substance in the water was causing the staining of teeth: FLUORIDE

9 Mother Nature is Replicated: Community Water Fluoridation Begins A 21 city study is undertaken to replicate what Mother Nature has taught us Grand Rapids, Michigan was the first city to adjust fluoride concentration in public drinking water (1945) Cavity rates dropped dramatically

10 At the time CWF was initiated Almost everyone had tooth decay No one knew how to prevent it Not uncommon for 13-year-olds to have lost one or more permanent teeth to decay About half of older Americans (age 65+) had lost all their natural teeth Recruits into WWII rejected because of poor oral health (6 opposing teeth -10% rejection rate; 40% needed immediate treatment for relief of pain)

11 How Does Fluoride Work?

12 How fluoride works Topical Effect From the outside of the tooth Saliva, fluoridated toothpaste and other topical products Systemic Effect From the inside and outside of the tooth Saliva bathes the teeth enamel 24/7/365 Adults also benefit from fluoride, rather than only children (as was once assumed)

13 How Fluoride Works Topically Fluoridation Basics Fluoride inhibits demineralization Fluoride enhances remineralization of surface enamel Dental plaque is fluoride reservoir releasing small amounts of fluoride when ph is lowered as we eat Fluoride is taken up more readily by demineralized enamel than by sound enamel Fluoride in saliva continuously bathing the tooth in fluoride Koulorides.

15 Are There Alternatives to Water Fluoridation-NO!! 1. Community Water Fluoridation: The Gold Standard 0.7mg/L (ppm): Reduces cavities by 25% Adults and children 2. Closest thing to a Magic Bullet we have 3. Fluoride toothpaste is not a replacement: CWF + TP 4. Fluoride Supplements: Compliance Terrible! 5. No alternative works as well or is as cost effective as CWF

16 HEALTH BENEFITS OF WATER FLUORIDATION? CAVITIES ARE REDUCED FOR ALL P.S.-Ya still gotta brush, floss, eat well, get dental checkups, and sealants

17 Is Water Fluoridation Still Necessary? YES! Effect of Starting Community Water Fluoridation: 25% cavity reductions Effect from Stopping CWF: Huge increases in cavities Calgary, Alberta, Canada-stopped 2011 Cavity rates have skyrocketed 146%

18 Why do cavities matter? The most common chronic disease for children and teens. It s at least 2-3 times more common than asthma and obesity, 20 times than diabetes Severe pain (toothaches) Difficulty in chewing Poor weight gain Difficulty concentrating Predictor of cavities later in life Costly to treat Deaths

19 CAVITIES: Unevenly Distributed Low income kids are more than twice as likely to experience tooth decay The disadvantaged bear a disproportionate burden of cavities

20 Operating Room Full Mouth Restorations reduced by 2/3 to 3/4ths by CWF U.S. and International studies confirm benefits for children CWF decision-makers & Water Operators prevent more cavities by fluoridating the water than all of us can do (Sources:.

22 A (big) ounce of prevention The CDC has called fluoridation one of 10 great public health achievements of the 20th century. Fluoridation reduces tooth decay by 25% over a lifetime protection beyond what is offered by fluoride toothpaste and other preventive methods. Over 211 million U.S. residents, 3 out of 4 people on community water systems, have access to optimally fluoridated water.

24 Fluoride & Fluoridation: The Village 400 mile view Grassroots view

25 The Two Villages Immediate Challenge: Timeline-extremely short Key claims being made Department of Health Local, state, and national group support-healthcare, coalitions Key influencers in community Faith-based community Building support for initiation Timeline-months to years Key claims being made Department of Health Local, state, and national group support-healthcare, coalitions Key influencers in community Faith-based community

26 The Two Villages Immediate Challenge: Timeline-extremely short Key claims being made Department of Health Local, state, and national group support-healthcare, coalitions Key influencers in community Faith-based community Immediate Challenge: Who will lead? Who will follow? Who s in the sandbox? It takes a Village
