Obviously, good parents want their children to have strong teeth. Yet, in spite of the improvements in dental care in recent years, a quarter of two to five year olds and half of children 12-15 have had one or more cavities. Further 2/3 of 16- to 19-year-olds have had dental problems. To counteract this, many suggest that adding fluoride to public water will help. Others say it will do more harm than good.



Fluoride is the 13th most common element in the Earth's crust and exists naturally in water. Some water has sufficient natural fluoride. But what if it is not naturally present? Should fluoride be added to water systems? The debate about fluoride won't be settled here. Rather, the purpose of this article is to consider a few of these points, and to give you some options.

Consider these quotes: "It is well known that fluoride helps prevent and even reverse the early stages of tooth decay." "Today, water fluoridation is estimated to reduce tooth decay by 20-40%." These statements were made by a medical doctor. Here's another: "For over 60 years, water fluoridation has proved to be a safe and cost-effective way to reduce dental caries."

Those favoring the addition of fluoride in water claim that its presence combats tooth decay in two ways. First, it strengthens the developing teeth. Second, it also aids the surface of the teeth by preventing the acid produced by the bacteria in plaque from dissolving, or demineralizing, tooth enamel. Fluoride also allows teeth damaged by acid to remineralize, or repair themselves. It won't repair cavities, but it can reverse minor tooth decay and prevent new cavities from forming.

The other side makes statements like these: ". . . there is no difference in the tooth decay rates of the fluoridated and nonfluoridated areas surveyed." They even claim that increased amount of fluoride in children also increases tooth decay.

Too much fluoride during the teeth developing years can cause enamel fluorosis, a mottling or discoloration of the permanent teeth. To add fluoride to water, along with toothpaste and treatments can exceed the maximum level that is safe.

Symptoms of fluoride toxicity may begin 30 minutes after an overdose and last up to 24 hours. These symptoms include increased thirst, vomiting, nausea, diarrhea, abdominal pain, or increased salivation.

At times the studies have not considered the long range effects of fluoride. The con side says it has been directly linked to cancer, changes in bone structure and strength, has caused birth defects and perinatal deaths, has impaired the immune system, caused initial stages of skeletal fluorosis, caused osteoarthritis, inhibits key enzymes, suppresses thyroid function and several other adverse problems.

What about the studies mentioned above proving that fluoride is good for dental hygiene? Opponents point out the studies had several flaws. First, they did not consider other minerals in the water that could have been the cause of decreased instances of tooth decay. Second, they did not consider the differences between "natural fluoride" (like CaF) and added fluoride (like NaF). Third, the conclusion had little or no statistical analysis. Fourth, it included no safety experiments except for dental fluorosis.

If your conclusion from these points is that fluoride should not be in your drinking water, what can you if it is? Some opt for bottled water but this gets expensive. A better alternative is to purchase a water filter that removes fluoride. Some expensive units do this. Other less expensive units have optional fluoride filters. The Berkey, for example, has available an additional filter that can we attached below the regular charcoal filters and will remove fluoride from the water. If you don't want fluoride, you don't have to drink it.
