"The Impact of Insufficient Fluoride: Dental Health Expert Reveals"

What is fluoride and why is it important?

Fluoride is a naturally occurring mineral that helps prevent tooth decay and keep your bones strong, says Scott L. Tomar, DMD, DrPH, a spokesperson for the American Dental Association (ADA) and professor at the University of Illinois Chicago College of Dentistry. Fluoride’s key role is to help reduce tooth decay while strengthening tooth enamel.

The ADA states that fluoride can be delivered topically and systemically. Ingesting it through drinking water or supplements can strengthen teeth from the inside out, while applying fluoride to teeth with toothpaste or during dental treatments can help prevent cavities.

What happens when you don’t get enough fluoride?

Most people in the U.S. get enough fluoride from their diet and dental products, but not everyone. There is a concern around the loss of access to fluoridated tap water.

Dental caries are considered one of the most chronic diseases in American children. Studies show that those who drink fluoridated water have fewer cavities. Without adequate fluoride, there is a higher risk of tooth decay, dental problems, bone fractures, weaker tooth enamel, weaker teeth, higher dental costs, and missed school days due to dental issues.

Who might be at risk of low fluoride intake?

People in non-fluoridated communities, those who drink bottled or specialty filtered water, individuals using fluoride-free toothpaste, and kids with restricted diets or poor dental hygiene may have lower fluoride intake.

How to make sure you’re getting enough fluoride

Aim for a balanced approach to fluoride intake. Common methods include drinking fluoridated tap water, using fluoridated toothpaste, mouthwash, and getting topical treatments like fluoride varnish. Dietary sources of fluoride in tea, coffee, and raisins can also contribute to fluoride intake.

Is it possible to get too much fluoride?

While possible, getting too much fluoride is uncommon. Fluoride levels are carefully regulated in the U.S. to prevent fluorosis and skeletal fluorosis. Over-the-counter dental products contain low levels of fluoride, minimizing the risk of excessive intake.

Why is there confusion in the U.S. about fluoride and fluoridation benefits?

Misinterpretation of research, spread of misinformation, and mistrust of medicine contribute to confusion around fluoride. However, the scientific community supports fluoride as a safe preventive measure against tooth decay.
