Why is it important to have fluoride in drinking water?
Drinking fluoridated water keeps teeth strong and reduces cavities (also called tooth decay) by about 25% in children and adults. By preventing cavities, community water fluoridation has been shown to save money both for families and for the US health care system.
What is the fluoride level in drinking water?
4.0 mg/L The current enforceable drinking water standard for fluoride is 4.0 mg/L. This is the maximum amount that is allowed in water from public water systems, also called the Maximum Contaminant Level (MCL).
What are the cons of fluoride in drinking water?
The Cons of Fluoride in Drinking Water Fluoride dosage cannot be controlled, meaning that 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, creates pits in teeth or even break the enamel of the teeth.

Is fluoride used in water purification?
Fluoridation is the addition of small amounts of fluoride to drinking water to prevent tooth decay.

How important is fluoride?
Fluoride helps prevent tooth decay by making the tooth more resistant to acid attacks from plaque bacteria and sugars in the mouth. It also reverses early decay.
What’s the benefit of fluoride?
Fluoride, a naturally-occurring mineral, helps prevent cavities in children and adults by making the outer surface of your teeth (enamel) more resistant to the acid attacks that cause tooth decay.
What is natural fluoride?
Fluoride is a naturally-occurring mineral which is found in all natural waters to some extent – both seawater and fresh water. It is the 13th most abundant element on the Earth’s crust; a chemical Ion of Fluorine. Fluorine is the gaseous form; Fluorite the crystal form. Both contain Fluoride.
How much fluoride is too much?
In 1986, guidelines from the U.S. Environmental Protection Agency (EPA) established a maximum allowable concentration of 4.0 mg/L fluoride in public drinking water systems to prevent adverse effects from fluoride exposure (such as bone disease) and a recommended maximum concentration of 2.0 mg/L to prevent dental …
What is the role of fluoride?
Fluoride is commonly used in dentistry to strengthen enamel, which is the outer layer of your teeth. Fluoride helps to prevent cavities. It’s also added in small amounts to public water supplies in the United States and in many other countries. This process is called water fluoridation.
Is fluoride the same as chlorine?
Chloride and fluoride are chemicals commonly found in soil and rocks. Although chloride and fluoride belong to the same chemical group (the halogens), their behavior in the environment differs. Chloride is very mobile in ground water, while fluoride is rendered immobile in the presence of aluminum and iron oxides.
