Fluoride in the Water – Good or Bad?
Obviously, good parents want their children to have strong teeth. Yet, in spite of the improved toothpastes and professional dental techniques and equipment, more than one quarter of 2- to 5-year-olds and half of kids 12 to 15 years old have one or more cavities, and tooth decay has affected two thirds of 16- to 19-year-olds. Many agree with studies that seem to indicate that adding fluoride to public water will decrease the problem of tooth decay. Others strongly disagree.
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. We need to answer the question, do you need a fluoride water filter?
The pro side says, “For over 60 years, water fluoridation has proved to be a safe and cost-effective way to reduce dental caries.” “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 quotes come from an MD.
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.
On the other hand we have quotes like this: “. . . there is no difference in the tooth decay rates of the fluoridated and nonfluoridated areas surveyed.” Indeed, some studies, they say, show that the more fluoride children ingest, the higher their risk of dental decay.
Too much fluoride during the years the teeth are developing 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.
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 you conclude that fluoride should not be in your drinking water, what can you do about it? You could buy bottled water but this is expensive. A better choice is to purchase a water filter that removes fluoride. The Berkey Filters, for example, has available an additional filter that can be attached to the regular charcoal filters and will remove fluoride from the water. You don’t have to ingest it if you don’t want to.
