Why is chlorine and fluoride added to water?

Answer 1

Fluoride is added to publicly supplied drinking water for its prophylactic benefit in retarding or preventing toot decay, especially in growing children. That happens because tooth enamel acts as a semi- permeable membrane and allows the passage of fluoride ion necessary to impart decay resistance. It is much the same as prophylactic fluoride treatments that dentists provide to children during routine dental visits--only in much lower concentration.

Answer 2

Answer:

It is added to the water to reduce tooth decay.

Fluoride is not bad for you. It is considered by most public health experts to be one of the major advances in public health of the last century. Unfortunately, it has become politicized and the target of internet conspiracy theorists. What one must remember is that everything is toxic (even water and oxygen) at high enough levels. "The dose makes the poison" and so when reading the claims of people citing support to the claims of the evils of fluoride one must pay attention to make sure they are not citing industrial exposures, high dose supplements, etc etc.

• It does reduce tooth decay dramatically.
• It saves society money by promoting better health.
• It is associated with less gum disease, which may be a contributing factor in Heart disease.
• Nearly all dental fluorosis (mottling of the teeth from too much fluoride) is from eating toothpaste or taking too much supplementation in pill form, not from drinking water.
• There is no credible evidence that it causes cancer.
• There is no credible evidence that fluoride from drinking water causes osteoporosis or fractures (taking high dose pills can and studies of drinking water are on-going).
• There is no credible evidence that it causes birth defects, ADD or other toxicity at the doses found in water.
• It is not plausible that dentist are uninformed about such a central issue of dental health, especially one that is so publicly and actively debated. If the stat about dentists in areas with fluoridated water is true that is probably because those areas are more affluent and health conscious.
