Obviously, dental hygiene is a priority to conscientious parents. However, despite improved toothpaste and professional dental techniques and equipment, more than a quarter of the 2 - to 5-year-olds and half of children 12-15 years old have one or more cavities and tooth decay affects two thirds of 16 - to 19 - olds. Many feel that adding fluoride public water supply is one way to stop the problem of caries. However, this opinion does not in any way of thinking.
Fluoride exists naturally in water and 13 The most common element in the Earth's crust. Some water has enough natural quantities. What to do when they are not naturally present? If the fluoride added to water supply? The debate has been going on for decades, and will not end here. Many factors are involved in this debate. The purpose here is to consider some of these, and give you some options.
Consider the following quote: ". It is known that fluoride helps prevent and even reverse early stages of tooth," "Today, water fluoridation is estimated to reduce tooth decay by 20-40%." These statements by the physician. Here's another: "For more than 60 years, water fluoridation has proved to be a safe and economical way to reduce tooth decay ."
Pro side claims that fluoride fights tooth decay in two ways. First, it becomes part of the structure of developing teeth. Secondly, also works when it comes in contact with the tooth surface. Fluoride prevents acids produced by 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, alone. Fluoride can not 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 rates of tooth decay and fluoridated areas surveyed nonfluoridated "Indeed, some studies, they say, show that children ingest more fluoride, the higher the risk of caries .
Too much fluoride before 8 years, when teeth are developing, can cause enamel fluorosis, discoloration or mottling of permanent teeth. Sometimes the amount of fluoride ingested from water, and then the toothpaste and dental treatments can be too.
During the study did not take into account the long range effects fluorida.Con side says that it is directly linked to cancer, changes in bone structure and strength, caused birth defects and perinatal death, with a weakened immune system due to the initial phases of skeletal fluorosis , caused by osteoarthritis, inhibits key enzymes, suppresses thyroid function and several other adverse problems.
The studies mentioned prove that fluoride is good for hygiene? Opponents say the study had several shortcomings. First, it did not take into account other minerals in the water that could be the cause of reduced cases of caries. Secondly, they take into account the differences between "natural fluoride" (such as CAF), and added fluoride (as NaF). Third, the conclusion is little or no statistical analysis. Fourth, that no safety experiments, except for dental fluorosis.
If you conclude that fluoride should not be drinking water, you can do about it? You can buy bottled water, but it is skupo.Bolji choice is to buy a water filter that removes fluoride. Berkey, for example, has available an additional filter that can be plugged into a regular charcoal filters will remove fluoride from water. You do not have to take it if you do not want.
Symptoms of fluoride toxicity may include nausea, diarrhea, vomiting, abdominal pain, increased salivation, or increased thirst. Symptoms begin 30 minutes after ingestion and can last up to 24 hours.
