Fluoridation in Drinking Water

Adding fluoride in drinking water is a controlled step to minimize tooth decay. This water contains fluoride at a specific level which is effective in controlling cavities. Prevention of cavities can be done by addition of fluoride or by natural means. The fluoridated water works on the tooth surfaces. The process of adding fluoride in drinking water in the U.S. costs an average of $0.94 per individual annually. Read on to know more about

fluoridation in drinking water


The process of defluoridation is required when the levels of of natural fluoride level crosses the recommended levels. Bottled drinking water has has usually unknown levels of fluoride. Water filters meant for domestic use can remove fluoride from the water.

Dental Cavities

One of the major public health concern is dental cavities in many industrialized countries. This affects nearly 60-90% of schoolchildren and even a vast number of adults. Hence, fluoridation in drinking water can successfully prevent formation of dental cavities in both adults and children.

Several studies have indicated that

18 to 40% reduction

is seen in dental cavities when fluoride was added to drinking water supply and other sources of fluoride was available. Although, water fluoridation can result in dental fluorosis that alters the outlook of developing teeth. But most of the water fluoridation is mild and does not cause any concern for public-health.

Adverse Effects of Water Fluoridation

The adverse effects of adding fluoride to the water are very rare. The effects of fluoride depend on the daily intake from various sources of fluoride. The largest source is generally drinking water. The other sources include fluoridation of milk, salt and toothpaste.

As per the

U.S. Centers of Disease Control

, water fluoridation was listed among the public health achievements of 20th century. The ultimate goal of fluoridation in drinking water is to minimize a chronic disease that primarily targets the poor and children.

1 response to Fluoridation in Drinking Water

  1. More than 3,000 professionals (including over 270 dentists) urge the US Congress to stop water fluoridation citing scientific evidence that fluoridation, long promoted to fight tooth decay, is ineffective and has serious health risks. See statement: http://www.fluorideaction.org/statement.august.2007.html

    Also, eleven Environmental Protection Agency employee unions representing over 7000 environmental and public health professionals called for a moratorium on drinking water fluoridation programs across the country, and have asked EPA management to recognize fluoride as posing a serious risk of causing cancer in people. (b)

    Approximately, 80 US communities rejected fluoridation since 2008.
