Fluoride is harmul to bones (not teeth). Do you agree?

Question

Why do you agree or disagree? :p

Answer 1

how does it get to your bones unless u don't filter your water and the gov is putting in the water supply I filter all drinking water and spit out tooth past and mouth wash where it is really helpful.bones and teeth may both utilize calcium but they are definitely not the same fluoride helps to maintain healthy enamel by wicking in calcium from the saliva . if i'm not mistaken
I've heard flouride is decadent to the internal organs....

Answer 2

Bad for the bones? Try bad overall. Take a look at the website . . .

Answer 3

flouride is not selective about the bone connective tissue it helps or harms...if it's bad for bones it's bad for teeth, if it's good for bones then it's good for teeth...

Answer 4

Harmful under higher concentrations or if it exceeds the body's threshold limit.

Higher concentrations
In high concentrations, fluoride compounds are toxic and can cause death. In mice, a "semilethal dose" is estimated to be 184 milligrams of stannous fluoride per kilogram of body mass. Fatalities have been reported in some human individuals at doses as low as 5 mg/kg of fluoride ion while symptoms of acute toxicity (e.g. gastrointestinal upset) have been reported to occur at doses as low as 0.1-0.3 mg/kg.

When ingested directly, fluoride compounds are readily absorbed by the intestines. Over time, the compound is excreted through the urine, and the half life for concentration of fluorine compounds is on an order of hours. It is thought that fluoride is taken out of circulation by the body and trace amounts become bound in bone. Urine tests are a good indication of high exposure to fluoride compounds in the recent past.

Skin or eye contact with many fluoride compounds in high concentrations is dangerous. In case of accidental swallowing, milk, calcium carbonate, or milk of magnesia is given to slow absorption. Eye or skin contact is treated by removing any contaminated clothing and flushing with water.

Low concentrations

Fluoride is best known for its use in small quantities in an attempt to help reduce dental caries (cavity) frequency in teeth. Some studies suggests that fluoridation is associated with a median decline in the number of children with caries of 12.5%, and a median decline of 2.25 teeth with caries

Fluoride compounds, usually calcium fluoride, are naturally found in low concentration in drinking water and some foods, such as tea. The ocean itself has an average concentration of 1.3 ppm (parts per million). Fluoride ions replace hydroxide ions in calcium hydroxyapatite, Ca5[(PO4)3OH], in teeth, forming calcium fluoroapatite, Ca5[(PO4)3F], which is more chemically stable and dissolves at a pH of 4.5, compared to 5.5 pH for calcium hydroxyapatite. This is generally believed to lead to fewer cavities, since stronger acids are needed to attack the tooth enamel.

The most widely accepted adverse effect of low concentration fluoridation at this time is fluorosis. It is a condition caused by 'excessive' intake of fluorine compounds over an extended period of time, and can cause yellowing of teeth, hypothyroidism, or brittling of bones and teeth. The definition of 'excessive' in the context of fluorosis falls on the order of parts per million and is generally accepted to mean significantly higher than the 0.7 to 1.2 ppm amounts recommended for fluoridated water. However, dosage is crucial to adverse effects, and therefore, what concentration is problematic will depend on the amount of fluoride ingested, how much is absorbed, and the weight of the person ingesting it. For this reason, many doctors have advised against using fluoridated water to make up formula for infants. However, this may be more due to the chemical interaction of fluoride with the calcium in the formula producing CaF2 which will precipitate out of the body within the stool of the infant, thereby decreasing its absorption. People with kidney problems, or those on dialysis, are also advised not to ingest fluoridated water.
