FLUORIDE: Frequently asked Questions

What is fluoride?
Fluoride is a mineral that occurs naturally in all water sources. It is an ion that comes from the element fluorine and is always found in combination with another element. Fluorine is the 13th most common element on the planet. Fluoride has been proven to be effective in preventing and even reversing the early signs of tooth decay.

Our county water has fluoride, isn't that enough?
County water, if it is fluoridated, goes a long way toward ensuring that you are getting enough into your system. Today there is a tendency to filter the water we drink, or to drink bottled water and we may not be getting the fluoride we need into our systems. Topical treatments through the dentist or through the use of fluoride toothpastes helps. If necessary fluoride supplements can be used.

How much fluoride is in the water supply?
The amount of fluoride in the public water supply varies between municipalities. Though, the Environmental Protection Agency has determined that the "optimal" range for fluoride in water should be between 0.7 and 1.2 ppm (parts per million). The upper limit allowed by the EPA in public water supplies is 4 ppm. Backed by results from more than 140 documented studies undertaken in 20 different countries over the past several decades, fluoridated water adhering to these standards has been scientifically established as safe for drinking. Fluoridation of community water supplies is the single most effective public health measure to prevent tooth decay and to improve oral health for a lifetime. NOTE: even in the correct amounts, fluoride or the disinfectant chlorine in drinking water, makes the water unsuitable for use in kidney dialysis machines or aquariums.

Isn't adding fluoride to the drinking water dangerous?
No. The addition of fluoride to water has led to the widespread improvement in dental health. Studies comparing areas with and without fluoridation showed significantly lower cavity rates in communities with fluoridation. 

Should I have fluoride applied at the dentist?
That is your own choice. The advantage to that type of application is that it goes directly into the teeth where fluoride is needed. It becomes part of an over-all preventive approach and increases the potential of you never losing your teeth.

Can fluoride be removed by boiling water?
No, fluoride cannot be removed by boiling. Boiling water for long time is also harmful as water will evaporate and get concentrated with fluoride and it should be avoided.

How do I reduce fluoride exposure?

• Don't take fluoride supplements.

• Consider using un-fluoridated toothpaste.

• Avoid drinking black tea. Black tea usually contains high amounts of fluorine.

• Be wary of tinned fish and canned food items.  Fluoride may be used as a preservative.

• Avoid black or red rock salt or items containing black or red rock salt.

• Avoid using chewing tobacco.

• Avoid long term use of medication that contains fluorine. Certain antidepressants   and medications for osteoporosis contain fluorine.
