[edit] Where is the Production section?
Am I the only one to find it odd that the article only details the use of this compound, and not it's production, such as Sodium chloride?--Happysomeone (talk) 02:34, 11 January 2008 (UTC)
[edit] Evidence
Does anyone have any evidens that sodium fluoride prevents cavities ??? My own research shows that it more proberly calcium fluoride which prevents cavities.
- Sorry can't provide you with evidence, perhaps some other user can. But there seems only 3 fluoride compounds are commonly used in commercial tooth paste as a decay retarding compounds. Stannous fluoride SnF2 (Tin fluoride), sodium monofluorophosphate or sodium fluoride. All these fluoride compounds are manufactured from hydrofluoric acid, which commercially is usually manufactured from fluorspar (calcium fluoride). So yes in a manner of speaking, calcium fluoride prevents cavities if you accept that sodium fluoride does. I have responded further on you talk page User talk:Equanimous2.--blue520 15:13, 17 April 2006 (UTC)
No, I don't accept that sodium flouride prevents cavities. I think calcium is an importen component. I just think that if we can't find hard evidence that sodium fluoride prevents cavities then it should be removed from the article or we should write that it is in the article with out any evidens.

There is an article at J Am Dent Assoc. 1959 Feb;58(2):43-55 titled "Dental caries in the molar teeth of rats. III. Bio-assay of sodium flouride and sodium lauroyl sarcosinate as caries-inhibitory agents." Unfortunatly I dont think its online. This might shed some light on the argument, though I dont have access to this particular year. However there is another article "Clinical evaluation of sodium flouride chewable tablets in dental caries." Indian J Dent Res. 1999 Oct-Dec;10(4):146-9. Abstract: Chewable tablets containing low dosage flouride content were prepared using two varities of celluloses and their in vitro parameters were evaluated. An eighteen month clinical trial revealed that both these formulations were effective in controlling the caries. However, ethyl cellulose is proved to be superior to methylcellulose as a controlled release matrix material in controlling caries. Thus this study recommends ethylcellulose matrix tablets containing low flouride content is an efficacious and cost effective drug device in controlling dental caries. So it is my belief that sodium flouride does indeed contribute to the prevention of cavities. Fitz05 21:46, 12 December 2006 (UTC)
[edit] Fluoride Toxicity and Removed Edits
Please stop removing reliable, substantiated content about the dangers of Sodium Fluoride. After posting the following under 'Saftey';
"Sodium Fluoride is toxic and has been linked to cancer, genetic damage and mental health implications. Its introduction into toothpaste and drinking water has caused outrage amongst many, who say that it is unethical, forced mass-medication."
... my addition was removed and I have been threatened with a block if I re-post. There are no grounds for removing this edit. I will re-post because the information and the source is reliable.
REVISED- Since re-posting it has once again been removed. This is not acceptable. Whilst admins can contact me, I can find no way of asking them for an explanation. Whilst I understand that the topic is 'contraversial' this makes it even more important to disseminate good information.
Please do not remove this post again.

[edit] Behavior on heating
What happens to NaF if you heat up to melting point in air vs pure nitrogen vs hydrogen nitrogen? Do you retain the original chemical? Does it decompose? Do you form HF and Na2O? Do you form Na metal, HF? —The preceding unsigned comment was added by 68.20.140.8 (talk • contribs) .
- In general, metal halides are very stable, and sodium fluoride is no exception. No element is more electronegative than fluorine, and only the heavier alkali metals are more electropositive than sodium, so it doesn't react with any of the gases you mention. —Keenan Pepper 22:12, 15 June 2006 (UTC)
[edit] Sodium fluoride is toxic
Guys, this article is crap, calcium fluoride in TINY trace amounts is good for the human body, sodium fluoride is HIGLY toxic. —The preceding unsigned comment was added by 24.122.133.80 (talk • contribs) .
Er... calcium flouride is also toxic. Sodium flouride is added to toothpaste and other such things, in small quantities. Fitz05 21:55, 12 December 2006 (UTC)
Calcium fluoride isn't retained by the body. Sodium fluoride and Stannous fluoride are toxic poisons that persist in your intestinal tract. The chemical weapon attacks your guts. —Preceding unsigned comment added by 68.53.200.234 (talk) 13:46, 30 April 2008 (UTC)
