Is fluoride beneficial or dangerous?

Fluoride is a naturally occurring mineral that has been shown to be beneficial in preventing tooth decay. When fluoride is added to toothpaste and other oral care products, it can help to strengthen tooth enamel and make it more resistant to decay. Fluoride is also added to some public water supplies in order to help prevent tooth decay in the community.

fluoride's effect on your teeth

Fluoride can affect the dentition in a number of ways. The primary way that fluoride helps to protect teeth is by strengthening tooth enamel, the hard, protective outer layer of the tooth. When fluoride is present in the mouth, it is incorporated into the enamel, making it more resistant to acid attacks from plaque bacteria and sugars. This can help to prevent tooth decay, also known as cavities.

Fluoride can also help to remineralize tooth enamel, which means it can help to repair small areas of tooth decay before they develop into larger cavities. Fluoride can also inhibit the growth of bacteria in the mouth, which can help to keep the mouth clean and reduce the risk of tooth decay.

In addition, fluoride can help to reduce tooth sensitivity and can be beneficial in preventing periodontal disease (gum disease).

It is important to note that excessive fluoride intake can cause dental fluorosis, a condition that can lead to discoloration and/or pitting of the teeth. Therefore, it is important to use fluoride products as directed and to not consume excessive amounts of fluoride.

But how can fluoride be dangerous?

While fluoride is considered safe and beneficial when used in the recommended amounts, excessive fluoride intake can be dangerous.

Excessive fluoride intake can cause dental fluorosis, a condition that can lead to discoloration and/or pitting of the teeth. Dental fluorosis occurs when the developing teeth are exposed to excessive amounts of fluoride while they are forming. Symptoms can range from mild white spots on the teeth to severe staining and pitting.

High levels of fluoride intake can also lead to skeletal fluorosis, a condition that can cause bone and joint pain. Skeletal fluorosis occurs when fluoride accumulates in the bones over time, leading to stiffness and pain in the joints. In severe cases, it can also lead to deformities of the bones and can cause damage to the nervous system.

Ingesting products containing fluoride (such as toothpaste) can cause nausea, vomiting, and stomach pain.

It is important to use fluoride products as directed, to not consume excessive amounts of fluoride and to talk to a dentist or healthcare professional for personalized advice regarding fluoride use.

So what is the recommended intake of fluoride?

The recommended dosage of fluoride intake varies depending on a person’s age, overall health, and the level of fluoride in their community’s water supply.

The American Dental Association (ADA) recommends the following guidelines for fluoride intake:

Infants up to 6 months old should not be given fluoride supplements.
Infants between 6 and 12 months old should be given a fluoride supplement of 0.25 milligrams (mg) per day if they are not receiving fluoride from other sources.
Children between 1 and 3 years old should be given a fluoride supplement of 0.5 mg per day if they are not receiving fluoride from other sources.
Children between 3 and 6 years old should be given a fluoride supplement of 1.0 mg per day if they are not receiving fluoride from other sources.
Adults should not take fluoride supplements unless advised to do so by a dentist or healthcare professional.

It’s important to remember that the fluoride from all sources should be taken into account, including fluoride from drinking water, toothpaste, mouthwash and other sources. Too much fluoride intake can lead to dental fluorosis. It is always recommended to consult with a dentist or healthcare professional for personalized advice regarding fluoride use.
