[78] Other agents to prevent tooth decay include antibacterials such as chlorhexidine and sugar substitutes such as xylitol. [81] A 2007 Italian review suggested that water fluoridation may not be needed, particularly in the industrialized countries where cavities have become rare, and concluded that toothpaste and other topical fluoride are the best way to prevent cavities worldwide. [12] The World Health Organization reports that water fluoridation, when feasible and culturally acceptable, has substantial advantages, especially for subgroups at high risk,[8] while the European Commission finds no benefit to water fluoridation compared with topical use. [9][12] No clear evidence of other adverse effects exists, though almost all research thereof has been of poor quality. Fluoridated salt reaches the consumer in salt at home, in meals at school and at large kitchens, and in bread. [82], Naturally fluoridated water is used by approximately 4% of the world's population, in countries including Argentina, France, Gabon, Libya, Mexico, Senegal, Sri Lanka, Tanzania, the U.S., and Zimbabwe. MMWR. This, also, stabilizes naturally soft water so corrosion can be minimized in the water distribution system and plumbing of customers. [9] A 2016 review found variable quality evidence that, overall, stopping of community water fluoridation programs was typically followed by an increase in cavities. [57] Other sources include dental products other than toothpaste; air pollution from fluoride-containing coal or from phosphate fertilizers; trona, used to tenderize meat in Tanzania; and tea leaves, particularly the tea bricks favored in parts of China. Assuming the worst case, with the lowest estimated effectiveness and highest estimated operating costs for small cities, fluoridation costs an estimated $17–$26 per saved tooth-decay surface, which is lower than the estimated $100 to restore the surface[2] and the estimated $169 average discounted lifetime cost of the decayed surface, which includes the cost to maintain the restored tooth surface. [14] In many industrialized countries swallowed toothpaste is the main source of fluoride exposure in unfluoridated communities. [32] A 2016 review of studies published between 1995 to 2013 found that water fluoridation in the U.S. was cost-effective, and that it was more so in larger communities. Rivers and lakes generally contain fluoride levels less than 0.5 mg/L, but groundwater, particularly in volcanic or mountainous areas, can contain as much as 50 mg/L. Because fluoride levels in water are usually controlled by the solubility of fluorite (CaF2), high natural fluoride levels are associated with calcium-deficient, alkaline, and soft waters. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. Supply of fluoridated water forces those who do not so wish to also consume water with added fluoride. [13] Fluoride's effects depend on the total daily intake of fluoride from all sources. Some countries and communities have discontinued fluoridation, while others have expanded it. In infants 80–90% of absorbed fluoride is retained, with the rest excreted, mostly via urine; in adults about 60% is retained. Oral Health in America: A Report of the Surgeon General. [32], Fluoridation has little effect on risk of bone fracture (broken bones); it may result in slightly lower fracture risk than either excessively high levels of fluoridation or no fluoridation. The use of fluoride in its various forms is the foundation of tooth decay prevention throughout Europe; several countries have introduced fluoridated salt, with varying success: in Switzerland and Germany, fluoridated salt represents 65% to 70% of the domestic market, while in France the market share reached 60% in 1993 but dwindled to 14% in 2009; Spain, in 1986 the second West European country to introduce fluoridation of table salt, reported a market share in 2006 of only 10%.
