This is an especially controversial subject in Spokane, where the debate over adding fluoride to our drinking water comes up for vote on a regular basis. Proponents cite fluoride’s dental benefits, while others argue that some people are actually allergic to fluoride. Where do you stand on this issue?

Drinking Tap Water May Help You Avoid Dentist’s Drill

Tooth decay affects children in the United States more than any other chronic infectious disease, according to the Centers for Disease Control and Prevention (CDC). The CDC states that tooth decay, if left untreated, can cause pain and infections that hinder eating, speaking, playing and learning. The controlled addition of a fluoride compound to public water supplies is considered to be the most cost-effective way to prevent cavities and fight tooth decay, according to a study published in the January/February 2010 issue of General Dentistry, the Academy of General Dentistry’s (AGD) peer-reviewed clinical journal.

“Fluoride makes the entire tooth structure more resistant to decay and promotes remineralization, which aids in repairing early decay before damage is even visible,” said C.H. Chu, BDS, PhD, MAGD, ABGD, lead author of the study. “Studies have confirmed the most effective source of fluoride to be water fluoridation.”

More than 144 million United States residents in more than 10,000 communities drink fluoridated tap water, providing an automatic defense against the harmful ingredients that cause such a preventable oral health disease.

“Instead of drilling holes to fix cavities, dentists would rather educate the public on how to avoid developing tooth decay in the first place,” said Cynthia Sherwood, DDS, FAGD, spokesperson for the AGD. “Drinking tap water to receive fluoride is safe, and it’s easier on your wallet than going to the dentist for a filling.”

The second-most effective source of fluoride is varnish. Varnish, applied quickly and easily by a dentist, is one of the most concentrated products available commercially. Varnishes that contain sodium fluoride adhere to tooth surfaces when saliva is present, providing an excellent fluoride treatment.

Keeping fluoride in the mouth enhances its ability to arrest demineralization and promote remineralization, and varnishes are better for this purpose than fluoridated drinking water or toothpaste. Fluoride varnishes are typically used for patients who don’t receive enough fluoride from other sources.

“The bland flavor and simplicity of the varnish method also makes it well-tolerated by young children and special needs patients,” Dr. Chu said.

Dr. Chu looked at the effectiveness of fluoride in specialty milk and salt products, toothpaste, mouthrinse and gum, but found that only the water fluoridation and varnish methods had the ability to reduce cavities by more than 30 percent.

Patients who suspect that they have a cavity should visit a general dentist right away.

    Fluoride is neither a nutrient nor essential for healthy teeth. Fluoride, as a drug in toothpaste and dental treatments, hardens tooth enamel from topical application. Modern science indicates that ingesting fluoride does not reduce tooth decay but does unnecessarily expose entire populations to fluoride’s adverse effects. Besides it doesn’t make any sense to dose people with anything based on thirst. Just a little too much fluoride can damage bones and developing teeth.

    People are conditioned to resist over consumption of harmless nutrients such as Vitamin C; but their fear antenna doesn’t go up about fluoride.

    And that’s because people make money off of fluoride and not from nutrients.

    And a nasty little secret is that the fluoride chemicals added to water supplies are tainted by-products of phosphate fertilizer manufacturing which are never purified before getting injected into your drinking water.
