Benefit for Adults CWF benefits everyone in the community, including adults and seniors as well as children.
The combined results of 9 studies (7853 participants) examining the effectiveness of water fluoridation in preventing tooth decay in adults were found to be significant at p : Although adults are as likely to experience new caries as children, certain segments of the US adult population—those with low incomes and the elderly—may have little or no access to restorative or preventive clinical care.
Safety of CWF The scientific evidence base continues to support CWF as a safe and effective public health measure.
Reviews of the scientific literature on the health effects of fluoride in the last 18 years have been conducted by the National Health and Medical Research Council, Australian Government (2007) All of these reviews have found CWF to be safe and effective.
Limited access to restorative care increases the need for effective prevention; complications and pain and suffering are more likely if caries remain untreated.
The proportion of the US population comprised of older adults is increasing, most of these persons are likely to be dentate and at risk for dental caries, and many lower-income adults lack access to timely restorative care.
In reviewing the legal aspects of fluoridation, the courts have dealt with this concern by ruling that (1) fluoride is a nutrient, not a medication, and is present naturally in the environment; (2) no one is forced to drink fluoridated water because alternative sources are available; and (3) when a person believes that fluoridation interferes with religious beliefs, there is a difference between the freedom to believe, which is absolute, and the freedom to practice beliefs, which may be restricted in the public’s interest.
The majority of the NRC committee concluded that the MCLG of 4 mg/L is not likely to be protective against bone fractures.
The main federal law that ensures the quality of US drinking water is the Safe Drinking Water Act (SDWA).
Under SDWA, the US Environmental Protection Agency (EPA) sets standards for drinking water quality and oversees the states, localities, and water suppliers who implement those standards.
Overall, the prevalence of dental caries among children aged 12 to 17 years declined from 90% in 1971 to 1974 to 67% in 1988 to 1991, and the mean number of teeth that were decayed, missing, or filled (DMFT) as a result of caries declined from 6.2 to 2.8 during this period.
More recent data have been aggregated into different age groups of adolescents; for 12 to 19 year olds, the mean DMFT declined from 3.1 in 1988 to 1994 to 2.55 in 1999 to 2004.
