Fluoride In Drinking Water

As a mineral, fluoride is quite common in most water sources, fresh and sea water included. Underground sources like boreholes and wells have higher concentrations of fluoride.

The total fluoride concentration in seawater is estimated at 1.3 mg/liter, while the concentration in well water is estimated at 10 milligrams per liter. Fluoride found in human teeth and bones, and its benefits to dental health are well-documented. It’s for this reason fluoride is so prevalent in toothpaste and other dental related treatments.

How Fluoride Finds Its Way To Drinking Water?

There are several ways that fluoride gets its way into well and municipal water. First, there is a useful amount of fluoride in municipal water that’s added through fluoridation. It’s added to reduce tooth decay among the people who use it.

Fluoride added to water through fluoridation doesn’t affect the appearance, taste, and smell of water. As with wells, fluoride enters into the water naturally. Since fluoride occurs naturally in the form of fluorine, it’s quite common in groundwater and it can be in the recommended levels or higher.

What’s The Recommended Amount Of Fluoride In Water?

Community water fluoridation should be maintained at 0.7mg/L for it to offer preventative benefits. Drinking water fluoridated at 0.7mg/l is always useful for improving dental health and reducing dental fluorosis problems, which is why it is used in a lot of teeth strengthening and oral products.

Giving your kids fluoridated water helps optimize their intake of fluoride since it’s not easy to get through food or other means. Brushing teeth with toothpaste with high fluoride contents is also a great way to improve dental health and is especially helpful if you have gingivitis.

Are There Benefits To Drinking Fluoridated Water?

When you take fluoride in the recommended amounts, you’re sure to enjoy a variety of health benefits apart from just oral. Here are some well-documented benefits of drinking water with fluoride (assuming you have the right amounts).

1. Reduces Issues With Tooth Decay

Tooth decay is a major problem among small kids. Studies indicate that dental-related issues result in the loss of more than 164 million work hours and 51 million school hours each year. Getting municipal water fluoridated helps minimize tooth decay in adults and kids.

2. Reduce Cavity Problems Among People Of All Ages

It’s said that the fluoride present in municipal water systems reduces tooth decay and cavities among adults and children by up to 25%.

3. Super Safe And Effective

Several scientific pieces of evidence back the safety and effectiveness of municipal water fluoridation. Hundreds of health organizations have provided valid evidence regarding the benefits of water fluoridation in preventing dental decay.

Among these organizations include the World Health Organization, the American Academy of Pediatrics, Centers for Disease Control and Prevention, and the American Medical Association.

4. It’s Natural And Healthy

Fluoride occurs naturally in oceans and groundwater. Fluoridation is all about adjusting the fluoride levels in water to make it safe for human use and help prevent dental decay.

5. Saves People Money

Handling dental problems cost people, a good chunk of money daily. We all pay when it comes to treating dental problems. This is through higher taxes and health insurance premiums. It’s proven and confirmed that dental filling costs more than the lifetime cost of fluoridating water per person.

Common Ways You Can Consume Fluoride

Fluoride enters the human body either through swallowing or topical application. You can eat it in foods or consume it through water or other fluoridated drinks.

Is Fluoride Bad?

Fluoride is not harmful if taken in the right quantities. However, when taken in extreme, fluoride can trigger serious health problems. Based on an all-encompassing report issued by the National Research Council in 2006, it was discovered that giving kids foods and drinks high in fluorides increase the risk of them developing severe dental fluorosis.

Fluoride is not a hundred percent safe, especially when taken in high content, it may have some health effects. Always research the fluoride content in the water you are drinking to avoid exposing yourself to an extreme health effect.

Are There Health Effects Of Drinking Water With Fluoride?

Extreme consumption of water with high fluoride content isn’t good for your health. Clinical tests have confirmed that when taken in excess, fluoride can cause dental fluorosis. Dental fluorosis is a common disease found with kids below eight years.

It’s not a real threat in the modern-day world. However, it affects the cosmetic look of your teeth by leaving white spots or streaks on tooth enamel. The Centers for Disease Control and World Health Organization are still researching more about fluoride to know about its health effects.

Based on the World Health Organization, when your intake water that has more fluoride than the recommended amount, you’re at risk of suffering from skeletal and tooth fluorosis. These are several health problems that can leave you with weak teeth or bones, thyroid gland damaging, or joint impairment. Also, extreme water fluoridation increases the potential for bone cancer.

How To Get Rid And Minimize Exposure To Extreme Fluoride?

In this era and world, it’s not possible to avoid consuming fluoride. Even if you don’t like it, you will find yourself drinking, eating, or using products that have fluoride infused.

Since you cannot avoid, it’s best to know how to get rid of the already bio-accumulated fluoride. For those who would rather avoid than bear the consequences, the best thing to do is to increase your intake of the alkaline diet. Higher alkaline means lower fluoride. See our water ionizer reviews for more information.

Taking tamarind tea, high-selenium foods, and exercising more can also help reduce your consumption of fluoride. Here are simple ways to detoxify or remove extreme fluoride in the body. 

Bottom Line

Fluoride occurs organically, so it’s so prevalent in most water bodies. The water you get from wells, boreholes, rivers, and lakes have some fluoride content. Boreholes and well water is known to be extremely high in fluoride, so it may not be safe for drinking.

River and lake water is not so high in fluoride. As with bottled and spring water, you will find some brands that add fluoride to the water while others don’t. No matter the source of your drinking water, always make sure you aren’t taking more fluoride than you should.

Getting the municipal tap water tested is the best thing you can do to determine the quantity of fluoride presence. As for bottled water, you can enquire from the manufacturer to know the content of fluoride.
