Key Differences
Fluoridation is the process of adding fluoride to public water supplies to reduce the incidence of dental caries, while defluoridation is the reduction or removal of fluoride from water when its concentration is too high.
The main goal of fluoridation is to maintain fluoride at a level that balances benefits in preventing tooth decay and minimizing dental fluorosis, whereas defluoridation aims to lower fluoride levels to prevent skeletal and dental fluorosis.
Fluoridation is typically implemented in areas where natural fluoride levels are low and dental health issues are prevalent, while defluoridation is necessary in regions where fluoride levels exceed recommended limits due to natural geological conditions.
Techniques for fluoridation include adding compounds such as sodium fluoride, fluorosilicic acid, or sodium fluorosilicate, on the other hand, defluoridation methods involve using activated alumina, bone char, or reverse osmosis.
While fluoridation is a public health initiative endorsed by various global health organizations, defluoridation is often a corrective measure that addresses specific local environmental issues.

Fluoridation
To add a fluorine compound to (a drinking water supply, for example) for the purpose of reducing tooth decay.
Defluoridation
Defluoridation is the downward adjustment of the level of fluoride in drinking water. Worldwide, fluoride is one of the most abundant anions present in groundwater.
Fluoridation
(chemistry) The act or process of adding fluoride to something, especially water.

Common Curiosities
What is the main purpose of fluoridation?
The main purpose of fluoridation is to prevent tooth decay by adding fluoride to drinking water.
What are the risks of not implementing defluoridation where needed?
Not implementing defluoridation where needed can lead to dental and skeletal fluorosis, which are harmful to health.
How are fluoridation and defluoridation implemented?
Fluoridation is implemented by adding fluoride compounds to water, whereas defluoridation involves filtering out fluoride using various methods.
Are there any environmental impacts associated with defluoridation?
Defluoridation typically does not have significant environmental impacts, but it requires resources for the installation and maintenance of filtration systems.
Why is defluoridation necessary?
Defluoridation is necessary to remove excess fluoride from water, preventing fluorosis.
What are typical methods used in defluoridation?
Typical methods used in defluoridation include activated alumina absorption, bone char filtration, and reverse osmosis.
What are the health benefits of fluoridation?
The health benefits of fluoridation include reduced dental caries and improved oral health.
Can fluoridation lead to any health issues?
If not properly controlled, fluoridation can lead to dental fluorosis, which is why monitoring is essential.
What determines the need for defluoridation in a community?
The need for defluoridation is determined by the natural fluoride levels in the community's water supply exceeding safe limits.
Who endorses fluoridation and why?
Fluoridation is endorsed by organizations like the WHO, CDC, and ADA because it is a cost-effective public health measure to reduce tooth decay.
