Along for the (Fluo) Ride

By Arshya Gurbani, M.A. candidate 2018

Fluoridated water, at the right amounts, is beneficial for our dental care. In fact, the Centers for Disease Control and Prevention says it’s one of the ten greatest public health achievements of the 20th century! So why was it necessary for the Orange Water and Sewer Authority to shut down after a fluoridation leak (and water main break) last week? If you’re a resident of Chapel Hill or Carrboro wondering about the risks of “contaminated” water, questioning whether the closing of businesses and workplaces was a necessary loss of income, or if you’re just interested in the water you drink…look no further.

Here are 5 things you should know about the fluoridation of drinking water:

  • Fluoride has proven to be very effective in reducing tooth decay, in children and in adults (Centers for Disease Control)
  • It works by making your tooth enamel stronger which slows decay; it can also help reverse early tooth decay When you consume fluoride, it hangs out in your saliva and is bathes your pearly whites! (American Dental Association)
  • Recommended amounts of fluoride in drinking water are around 0.7 mg/liter—well below the identified danger zone of 2-4 mg/liter (Centers for Disease Control)
  • There’s no evidence that water at recommended levels in drinking water worsens or causes cancer (National Cancer Institute)
  • As of 2012, 75% of the U.S. Population had access to safe fluoridated water (American Dental Association).

On the other hand, there are some who believe that fluoride has no real benefits to adding fluoride to our water, and that in fact it may harm some populations, such as young infants. They note that most developed countries do not add any fluoride to their water, though some counter this by saying speculating that salt or other foods are supplemented.

So there is a bit of a debate on the subject. All things said, I’d be interested in knowing just how high fluoride levels got last week.

OWASA’s website posted this announcement, in case you’re local and are interested as well:

Customers are invited to receive information and to comment and ask questions about the water emergency in the OWASA Board of Directors’ meeting on Thursday, February 9th at 6 PM in the Chapel Hill Town Hall, 405 Martin Luther King Jr. Boulevard.
