Benefits of Fluoride

 

Fluoride is a natural mineral recognized for its critical role in preventing tooth decay and strengthening enamel. Backed by over 75 years of research, fluoride is endorsed by leading health organizations like the CDC and WHO for its ability to reduce cavities and improve oral health. Public water fluoridation is a safe, cost-effective, and equitable solution that benefits everyone, especially underserved communities, while reducing overall dental costs. Good oral health is linked to better overall health, reducing the risks of systemic conditions such as diabetes and heart disease.

NYSDOH Commissioner Highlights Water Fluoridation Health Benefits

Apr 14, 2025

Per the notice below, the Commissioner of the New York State Department of Health (NYSDOH) highlights the health benefits of water fluoridation.

Statement from State Health Commissioner Dr. James McDonald on Health Benefits of Water Fluoridation

"Safe and available water for drinking and for recreation promotes healthy people, healthy communities, and a healthy economy.  Considered to be one of the greatest health achievements in the past century, the New York State Department of Health supports optimal levels of water fluoridation as a significant and cost-effective public health measure.

"Fluoride is a mineral that is often naturally present in drinking water.  When it is not naturally present, adding it at low levels prevents tooth decay or cavities, the most common chronic childhood disease.  Drinking water with fluoride at the optimal level contributes to maintaining good oral health.  Scientists have found that when fluoride is removed from water, tooth decay increases across the population.

"Good oral health and physical health are inseparable.  Poor oral health can lead to oral conditions that cause inflammation in the mouth and signal a response in the body that can impact chronic diseases like diabetes and cardiovascular disease.  Loss of teeth due to dental decay can limit consumption of fruits and vegetables that impact chronic health conditions, especially in older adults.

"The benefits of proper dentition, or oral hygiene, which includes flossing and brushing twice a day, in addition to community water fluoridation, go beyond physical health.  Studies show poor access to dental care contributes to poor oral health and can have lifelong psychological effects and can be a barrier to self-confidence and social belonging.

"Because the fluoridated water supply reaches everyone equally, health disparities decrease, as we know not everyone has access to regular dentist checkups.  Water fluoridation provides everyone with the same starting opportunity of having a healthy smile.

"The low levels of added fluoride that we recommend for water systems are optimal for the promotion of dental health and the protection of public health.  When water is fluoridated at those levels, there is no reason for concern about health risk.  Water supply professionals continuously and carefully monitor these levels to ensure public safety.

"The U.S. Public Health Service recommends a fluoride concentration of 0.7 parts per million in drinking water, equivalent to three drops in a 55-gallon drum; this is a safe and effective level carefully chosen and monitored to prevent cavities.  Those New York State water systems that are fluoridated provide this safe level of fluoride.

"Water fluoridation is determined at the local level, and not all communities have fluoridated water.  However, currently, about 13 million New York State residents receive the benefits of water that is fluoridated or contains naturally occurring fluoride at approximately optimal levels.  The Department will continue to support the right of local municipalities to have this public health option for their communities."

 

 

Fluoride FAQ

What is fluoride and how does it protect teeth?

Fluoride is a natural mineral found in water, food, and dental products like toothpaste. It helps protect teeth by strengthening the enamel, the hard outer layer of your teeth. Before teeth break through the gums, fluoride helps make enamel stronger, reducing the risk of decay. After teeth emerge, fluoride continues to help by remineralizing weakened enamel, reversing early signs of cavities.

Is fluoride safe?

Yes, fluoride is safe when used as directed. Scientific studies conducted over decades have consistently shown that fluoride, at recommended levels, is safe and effective in preventing tooth decay. The recommended fluoride level for public water supplies in the United States is 0.7 milligrams per liter (mg/L) or 0.7 parts per million (ppm). The Centers for Disease Control and Prevention (CDC) has recognized water fluoridation as one of the 10 greatest public health achievements of the 20th century.

What is water fluoridation?

Water fluoridation is the practice of adding fluoride to drinking water to bring the level up to a point that helps prevent tooth decay. It is a simple and cost-effective way to ensure everyone in a community, regardless of age or income, gets the cavity-fighting benefits of fluoride.

Should children use fluoride toothpaste?

Yes, fluoride toothpaste helps prevent cavities and makes teeth stronger. For children under 3, use just a small smear of toothpaste (about the size of a grain of rice). For children ages 3 to 6, use a pea-sized amount. Always supervise children while brushing to ensure they use the correct amount and don’t swallow toothpaste.

Does NYSDA support fluoride use?

Yes, the New York State Dental Association (NYSDA) strongly supports the use of fluoride as a safe, effective, and proven method to prevent tooth decay and improve oral health. NYSDA advocates for the use of fluoride in public water supplies and encourages the continued use of fluoride-containing dental products such as toothpaste and mouth rinses. NYSDA believes that access to fluoride helps promote better oral health for all New Yorkers, particularly underserved communities who may have limited access to dental care.

How can I find out if my water supply contains fluoride?

You can contact your local water utility to inquire whether your community’s water supply is fluoridated. Many local water suppliers provide this information in their annual Consumer Confidence Report (CCR), which is available to residents. The CDC’s My Water’s Fluoride tool also allows you to search for the fluoridation status of your community’s water supply. If your water is not fluoridated, you can still get the benefits of fluoride through toothpaste, mouth rinses, and professional treatments from your dentist.

Debunking Misinformation

Myth

Fluoride is harmful and toxic.

Fact

Fluoride is a naturally occurring mineral, and the levels used in community water fluoridation are strictly regulated for safety. At optimal levels (0.7 mg/L), fluoride is not harmful.

Fluoridation is unnecessary because people can just use toothpaste.
While toothpaste is important, water fluoridation provides continuous protection for everyone, especially those without access to dental care. It’s a proven, equitable solution that reaches all members of the community.
Fluoride causes developmental or neurological harm in children.
Decades of peer-reviewed studies, including research from the CDC and WHO, have found no reliable evidence linking fluoride at recommended levels to neurological harm or developmental issues in children.
Fluoride leads to fluorosis and discolored teeth.
Dental fluorosis occurs only when children ingest excessive fluoride during tooth development. Fluoridated water at recommended levels is safe and effective and doesn’t cause fluorosis when used as directed.
