Is fluoride in water bad for you? Short answer: no. In fact, it’s quite the opposite. Fluoride has been regularly added to America’s public water system supplies to help strengthen teeth and prevent cavities since 1945.
According to the CDC or Center for Disease Control and Prevention, the addition of this mineral to drinking water has been found to reduce the risk of tooth decay by up to 25% for both children and adults.
If you have ever wondered, is fluoride in water bad for you, or does reverse osmosis remove fluoride in the water? This guide has all the answers you’ll need. We’ll outline what exactly this mineral is and explore the potential benefits and drawbacks of fluoride, how you can measure the amount of fluoride in your water, and how you can regulate your fluoride intake with home water filters or water softeners.
It is a mineral that can naturally be found in your teeth and bones. It’s also found in water, soil, plants, rocks, and even air. When we talk about the human consumption of fluoride, it is generally in regard to oral health. Dentists like fluoride because it strengthens the enamel of teeth, thus preventing the risk of forming cavities.
Outside of the dentist’s office, this mineral can also be used:
Fluoride is a mineral that’s naturally present in the earth. Primary fluoride sources include:
The primary benefit of fluoride is that it strengthens tooth enamel. This may seem like a minor detail, but in reality, maintaining healthy teeth and oral health is an important way to also maintain a healthy body. Here’s why:
Tooth enamel protects the inner layers of your tooth from acids, bacteria, and plaque, all of which can lead to more serious severe illnesses. The reason has to do with the tooth itself. The inner layers of the tooth offer a direct path to the skeletal structures of your jaw and skull, circulatory system, and nervous system. The stronger the enamel, the more these parts of your body are protected.
Let’s look at how fluoride keeps your gnashers strong, plus other benefits of adding fluoride to water:
Fluoride, a naturally occurring mineral, can help prevent the loss of minerals from the tooth enamel and can also accelerate the repair process of putting minerals back into damaged enamel. Fluoride can also reduce acid production in your mouth, helping to prevent the formation of cavities in the first place.
Adding fluoride to water has proven effective when it comes to cavity reduction. But can too much fluoride ultimately cause your body harm?
An excess intake of fluoride can cause:
This condition typically occurs during the formation of childhood teeth when children consume too much fluoride from multiple sources. This may look like a child ingesting fluoride toothpaste in large quantities, or consuming too much fluoride via fluoride supplements, plus drinking fluoridated water.
This disease is most commonly found in countries like India and China, where there are longer periods of groundwater consumption with high levels of naturally occurring fluoride.
So should you be worried about an excess of fluoride in your tap water? Not necessarily. Some places have high levels of fluoride, which can cause health problems, as mentioned above, but typically the amount of fluoride found in groundwater is between a safe 0.01 to 0.3 parts per million. When groundwater approaches 4 parts fluoride per mission, it becomes hazardous.
Translation? There would have to be 400 times more fluoride parts per million than the typical groundwater contains. In fact, according to a study conducted by the U.S. Geological Survey, the fluoride concentration in most potable water wells sampled in the county were “below the optimal concentration recommended to prevent tooth decay.”
High amounts of fluoride in your drinking water is extremely unlikely. According to the study mentioned above, you’re more likely not to be getting enough fluoride than you are to be getting too much.
Just because fluoridating water is a common practice in the U.S. doesn’t mean the city you live in currently adds this mineral to its public drinking supplies.
To see whether or not your city fluoridates its water, head to the CDC website where there is a tool that allows you to see if your city adds fluoride to water and if so, how much. From there, you can gauge if your drinking water is providing enough fluoride for your health or if you need to increase your intake of this vital mineral.
So, is fluoride in water bad for you? The short answer: when consumed in safe amounts, fluoride can be highly beneficial to your overall oral health.
The suggested fluoride intake for adults over the age of 18 is a max of 3 milligrams of the mineral per day. Most public water systems in the U.S. contain .7 parts per million of fluoride. However, your county may not be introducing enough fluoride into the drinking water to ensure maximum health benefits for you, your family, and your whole community. In cases like these, it’s always best to take control of your health. Consider investing in a home water filtration system.
Home water filtration systems can:
Consider investing in a home water filtration system to control how much fluoride is in your drinking water..
