Fluoride in the Water - Good or Bad?
Obviously, dental hygiene is a priority to conscientious parents. 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. Many agree with studies that seem to indicate that adding fluoride to public water will decrease the problem of tooth decay. But this opinion is in no way unanimous.
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. Do you need fluoride water filters for your drinking water?
One side says, “Today, water fluoridation is estimated to reduce tooth decay by 20-40%.” “It is well known that fluoride helps prevent and even reverse the early stages of tooth decay.” These statements have the authority of a trained doctor. This one also: “For over 60 years, water fluoridation has proved to be a safe and cost-effective way to reduce dental caries.”
The pro side claims that fluoride combats tooth decay in two ways. First, it becomes part of the structure of developing teeth. Second, it also works when it comes in contact with the surface of the teeth. Fluoride prevents the acid produced by the bacteria in plaque from dissolving, or demineralizing, tooth enamel, the hard and shiny substance that protects the teeth. Fluoride also allows teeth damaged by acid to repair, or remineralize, themselves. Fluoride cannot repair cavities, but it can reverse low levels of tooth decay and thus prevent new cavities from forming.
Those on the other side of the debate claim that a greater quality of fluoride actually increases tooth decay. At least, they said, this is true: “. . . there is no difference in the tooth decay rates of the fluoridated and nonfluoridated areas surveyed.”
Fluorosis, a discoloration or mottling of the permanent teeth results when children 8 years of age or younger take in too much fluoride. During these years teeth are forming. To add fluoride to water along with what children get in toothpaste and dental treatments might well exceed this limit.
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. Berkey Water Filters, 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.
