Fluoride has been proven to increase the strength of bones and teeth, but there is little or no reason to believe that is needed for human life.
Sodium fluoride is harmful to the body because when ingested it robs the body the ability to absorb calcium.

Sodium fluoride is the only compound in sodium fluoride.
Fluoride itself is a monatmic ion of the element fluorine. It must be paired with a positive ion to form a compound. The fluoride in toothpaste is sodium fluoride. Some people confuse fluoride with the mineral fluorite (calcium fluoride), which is a compound.
Lead fluoride, PbF2
Sodium fluoride is harmful to the body because when ingested it robs the body the ability to absorb calcium.
Fluoride doesn't do anything on the outside of the body, unless in contact with with high concentrations of many fluoride salts, this can be dangerous. When intoxicated, it is possible to get Fluoride Poisoning. Fluoride also can be dangerous, in high concentrations, when in contact with the eye. ~HellsBaran

Calcium fluoride does not actually occur naturally in the human body and as such doesn't really contain a function. Outside of the body it is used in the production of materials.
Drinking water,toothpaste
Fluoride is only used by the body when it is in direct contact with teeth, they help fight caries in the earlier stages. There can also be some minor benefit to bone structure. Fluoride itself is not stored by the human body, because it is not a nutrient, it is an activating agent. Fluoride is toxic to the human body and ingesting fluoride will not help the teeth, instead it will be a strain on the body and consuming large amounts of fluoride will kill you. So don't eat toothpaste or drink mouthwash containing fluoride. Fluoridated water poses no health risk because of the low concentration, but can significantly improve dental health - especially in low-income areas. In other areas fluoride is present enough (in tooth-paste and other sources) to render the fluoridation of drinking water useless.
by consuming water which contain fluorine
Yes, because toothpaste contains fluoride which is poison to the human body. (If you swallow a big amount of toothpaste or drinks that include fluoride go to a doctor, if you swallow a little bit of fluoride you will be fine).
No, The fluoride ion is a reduced form of fluorine.
Fluoride is in many products available to the public. Fluoride is also known as Acidulated Phosphate Fluoride, Stannous Fluoride, Hydrogen Fluoride, Calcarea Fluorica, and Atomic Number 9.
AgF (silver (I) fluoride or argentous fluoride is a yellow-brown color. The compound AgF2 silver (II) fluoride or argentic fluoride is white.
