According to the Centers for Disease Control and Prevention (CDC), about 2/3 of Americans drink fluoridated public water. Public drinking water becomes fluoridated through a process of adjusting the naturally occurring fluoride levels in drinking water with chemical fluoride to the optimal fluoride levels recommended by the U.S. Public Health Service (0.7 – 1.2 parts per million) to prevent tooth decay. Studies have shown that fluoride prevents tooth decay by bonding with teeth to make them more resistant to acid attacks from bacteria. Since Grand Rapids, MI became the world’s first city to adjust the level of fluoride in its water supply in January of 1945, water fluoridation has been met with controversy. Take a look below at some of the pros and cons of water fluoridation:


  • Is endorsed by the American Medical Association (AMA), the American Dental Association (ADA) and the CDC as a safe and effective way to reduce cavities
  • CDC lists it as one of the top 10 more important public health measures of the 20th Century
  • Studies show that water fluoridation reduces tooth decay by about 25% over a person’s lifetime
  • Is the least expensive way to deliver the benefits of fluoride to all residents of a community, regardless of age, income, education, or socioeconomic status
  • For every $1 invested in water fluoridation, approximately $38 is saved in dental treatment costs
  • Greatest benefits are obtained by children who drink fluoridated water since birth; teeth made stronger during childhood would remain permanently resistant to decay


  • Many feel it is an unethical form of mass-medication as individuals do not give consent
  • Fluoride dosage cannot be controlled; people who drink more water ingest more fluoride
  • Excess fluoride exposure can lead to dental fluorosis, which creates white streaks or brown stains on teeth, can create pits in teeth or even break enamel
  • Research has shown that fluoride works best when it is applied topically, not ingested
  • Multiple studies have shown there is no significant link between fluoride exposure and tooth decay
  • Most developed nations, including Japan and 97% of western Europe, do not fluoridate their water
  • Studies have shown that even low levels of fluoride have been linked to negative health effects, like bone fractures, thyroid disorders, and impaired brain development and function

Whether fluoride in water is good or bad is up to you! If you feel fluoride in water is good, Quench’s standard 5-stage carbon filters will not remove fluoride. But if you feel fluoride in water is bad, we also have you covered – reverse osmosis filtration will remove fluoride from your office water.
