What is Fluoride and Why is it Added to Drinking Water?
Fluoride is a mineral that is naturally present in some water bodies and is added to others for the benefit of your mouth. The idea with adding fluoride to NYC water is to ensure that the teeth enamel is maintained and that tooth decay is prevented and the mouth a healthy one. The fluoride is now being added to drinking water in most societies and there are thought to be more than 200 million people in the world who are using fluoridated water.
The Pros and Cons of Fluoride in Drinking Water
If the debate over the use of fluoride in drinking water resembles a binary between the good and bad, then individuals will disagree on the pros and cons of this mineral. Among the benefits of fluoride in water:
Better dental hygiene: Fluoride in water can help your teeth be healthy, it can strengthen the enamel on your teeth and prevent cavities.
Access to care for a healthier mouth: When communities include fluoride in their drinking water, they can have access to oral care and prevent tooth loss.
Low cost: Fluoride addition to water is also a low-cost solution for oral health care in the communities with limited dental services.

Confusion: Drinking water with fluoride has been controversial and contested for years with different people having different perceptions about how good it is and how bad it is.
Is Fluoride in Drinking Water Safe?
Fluoride in water is another issue that’s also controversial, with some calling it dangerous and others saying it’s safe and effective. In some research, they even found that too much fluoride in water causes diseases like skeletal fluorosis, which makes the bones weak and brittle, and other harms to health. But other studies and professionals claim that fluoride concentrations in water are fine, and there is no proof of harms from drinking fluoridated water.
The Impact of Fluoride in Drinking Water on Children and Pregnant Women
Fluoride in drinking water affects children and pregnant women, too — some studies indicate that high fluoride levels have harmful effects on those groups. For kids, too much fluoride can cause dental fluorosis, where the teeth grow discolored and mottled. Fluoride in pregnant women is a cause of low birth weight and other health problems.

Others use fluoride-free toothpaste and other dental products, or take fluoride tablets on a doctor or dentist’s advice.
The History of Fluoride in Drinking Water
Fluoridation of drinking water goes back centuries: the first community water fluoridation scheme started in Grand Rapids, Michigan in 1945. Fluoride was then banned in drinking water, though some communities were acquiescing because it helped to save teeth, while others disapproved for safety and efficacy reasons. But even as this issue went to press, fluoridated water is a growing phenomenon, and it’s now estimated that more than 200 million people worldwide consume fluoridated water.
Does Fluoride in Drinking Water Improve Oral Health?
The issue of whether drinking water containing fluoride boosts the dental health is an open one, with many studies and experts on either side of the fence. There have been a few studies showing that drinking water fluoridated with fluoride prevents tooth decay in kids and teenagers. Other research, however, found that fluoride does not have much of an effect on tooth decay and other elements, including proper brushing and flossing and access to dentists, do.
The Science of Fluoride in Drinking Water
The study of fluoride in drinking water is multidisciplinary and a science where scientists work in various disciplines on the effects of fluoride on teeth, humans and the environment. Some researchers have found that fluoride added to drinking water reduces tooth decay (particularly in children and young adults), but other researchers have discovered that fluoride has a minimal effect on teeth. But even with this research, there is still disagreement and controversy about whether fluoride in water is safe and effective.
The Regulations of Fluoride in Drinking Water
Fluoride in drinking water is controlled by public health departments and guidelines and standards are established to ensure that fluoride levels in drinking water are human-safe. In the United States, for instance, the Environmental Protection Agency (EPA) limit the contaminant concentration of fluoride in water at 4 milligrams per litre. But even these rules are met with a number of people expressing concern over fluoride in drinking water and its effects on human health.
The Future of Fluoride in Drinking Water
There is no one way of knowing what will happen to fluoride in tap water, as different communities and countries apply different approaches. There are communities that are welcoming fluoride as a means to keep teeth healthier and to slow the progression of dental disease, and those that are turning it down because of concerns about safety and efficacy. However controversial it might be, fluoride in water will continue to be debated and studied in the coming years.
