Why Fluoride Doesn't Have a Place in a Biological Dental Practice

Fluoride & FluoridationJuly 16, 2026

In biological dentistry, we strongly believe that fluoride should not be incorporated, neither in a professional dental practice, nor in our daily lives. Fluoride has been researched by many countries for an extended period of time, and research has largely determined that it is toxic for general health when ingested regularly. While initial studies believed fluoride in daily use and as a toothpaste additive provided a benefit of protecting and strengthening teeth against cavities, recent studies have not been able to prove this link.

Many European countries have chosen not to add fluoride to their water supply, resulting in 97% of their population ingesting non-fluorinated water. Outside of Europe, most developed nations also do not fluoridate their drinking water. In the United States, however, most cities still add fluoride to their tap water, despite studies proving its negative health impact.

When researchers compared the rate of tooth decay in countries with and without fluoridated water over the last 50 years, the most compelling discovery is no difference of the rate of tooth decay between the two groups, which at a minimum confirms the use of fluoride in water and dental practice has no positive impact. The World Health Organization (WHO) conducted a specialized trend study on 12-year olds and their decayed, missing, or filled teeth (DMFT). The study demonstrates tooth decay rates have declined at the same rate in non-fluoridating countries as the United States.

We have established that fluoride does not have a positive impact in comparison to the avoidance of fluoride. But it is equally as important to consider the negative health impact of regular use and ingestion of fluoride. When ingested in unsafe amounts, fluoride can lead to multiple health issues, such as: damage to the developing brains of babies (64 studies have linked fluoride with reduced IQ in children), damage to the thyroid and pineal glands, arthritis through calcification of cartilage, bone disease, and increased risk of bone cancer, diabetes, and dental fluorosis.

Bone disease caused by too much fluoride is called skeletal fluorosis, which leads to chronic joint pain and stiffness. It can cause symptoms and degenerative changes that can resemble osteoarthritis. Recent research strongly suggests that fluoride can cause bone changes of fluorosis before it becomes evident on x-ray, therefore making it very difficult to diagnose in a timely or accurate manner.

A study has shown from 1950-2004, fluorosis in teeth increased from 10% in 1950 to 41% in the years 1999-2004. That is an increase of over 400% from levels found 60 years prior, a stunning uptick.

How can we protect ourselves against the use of fluoride in our water source? One solution is water filters. Filters using reverse osmosis, either attached to plumbing under the sink or pitchers that filter the water once dispensed, can eliminate up to 99% of fluoride.

Education with a multifaceted approach is the best route for successful oral hygiene and good general health. Patients need to properly care for their teeth at home, seek regular professional care to avoid gum disease, adopt an organic diet, and avoid toxic ingredients in their daily nutritional intake. Neither fluoridated water, fluoride in toothpaste, nor topical fluoride treatment used on children have a positive impact on cavity prevention. Investing in education and providing patients information on how to control plaque retention and adopt a healthy diet will render far better results for the oral health of this generation.
