Best Fluoride-Free Toothpastes

Your Guide to the Best Fluoride-Free Toothpastes and the Fluoride Controversy

In recent years, fluoride-free toothpaste has emerged as a significant topic in the world of oral health, driven by growing concerns over the potential toxicity of fluoride in water and the risk of fluorosis. Fluoride, long celebrated for its cavity-preventing properties, has faced scrutiny due to reports and studies suggesting its overexposure might lead to health issues. 

Dental fluorosis, in particular, manifests as changes in the appearance of tooth enamel in children who have been excessively exposed to fluoride during their teeth’s development. This controversy has sparked a debate about the safety and necessity of fluoride in dental products, leading to a rise in the popularity of fluoride-free toothpastes

Here are some key takeaways based on scientific research and recommendations from reputable institutions to help you understand better.

Is Fluoride Toothpaste Toxic? 

No, Fluoride toothpaste is not toxic.

There is widespread misinformation regarding fluoride, including claims that it is harmful to both the environment and health. In reality, fluoride is naturally present in the environment. Drinking water represents the main source of exposure to fluoride for humans.

Fluoride is commonly added to drinking water globally, with the U.S. Department of Health and Human Services suggesting a concentration of 0.7 parts per million.

Small amounts of fluoride are beneficial for the development of bones and teeth, but prolonged exposure to high levels of fluoride can negatively impact human health according to various studies.

What Are The Risks Of Using Too Much Fluoride?


Excessive fluoride exposure during tooth development can lead to dental fluorosis in children. Recent research highlights that while fluoride at low levels strengthens tooth enamel, too much can cause dental fluorosis, characterized by white spots, lines, or mottled enamel and weak mineralization. This condition typically affects children from birth to around nine years old, a crucial period for tooth formation.

A CDC survey revealed that about 25% of Americans aged 6 to 49 exhibit signs of dental fluorosis.


According to this Harvard study,Extremely high levels of fluoride are known to cause neurotoxicity in adults, and negative impacts on memory and learning have been reported in rodent studies”.

However, the fluoride concentrations in toothpaste and water are significantly lower than these harmful levels.

Does Fluoride Prevent Cavities?

For Adults

Yes, Fluoride helps prevent cavities.

Using fluoride toothpaste is a proven method to prevent cavities. It works by enhancing mineralization and strengthening tooth enamel against acid.

Toothpastes with the American Dental Association’s Seal of Acceptance all contain fluoride. 

The Centers for Disease Control and Prevention (CDC) has recognized water fluoridation as one of the 20th century’s major public health successes due to its role in reducing tooth decay. 

The World Health Organization (WHO) also endorses fluoridated toothpaste for cavity prevention, supported by extensive clinical research. For instance, a review of 54 studies found that fluoride toothpaste significantly lowers the risk of dental caries, particularly at 1500 ppm compared to 1000 ppm.

The WHO highlights that maintaining a low fluoride level in the mouth continuously is the most effective way to prevent dental caries. In 2019, the Cochrane Collaboration, known for thorough and independent research, reviewed a hundred studies and confirmed that fluoridated toothpastes are more effective than non-fluoridated ones in cavity prevention.

For Children

This advice is valid for adults, not for children. Indeed, during the period of tooth mineralization, an excess of fluoride can cause dental fluorosis, which is mainly characterized by stains on the teeth. For younger children, prefer a “special child” toothpaste. The fluoride levels recommended by health authorities are as follows:

  • Before 3 years, 500 ppm (50 mg/100 g) or less;
  • From 3 to 6 years, 500 ppm;
  • From 6 years, between 1,000 and 1,500 ppm.

Beyond 10 years, a toothpaste with a higher fluoride content can be used in cases where the risk of cavities is high. Care should be taken that the child does not ingest too much toothpaste.

Is Fluoride Really Necessary For Your teeth?

Medical research has long established that fluoride in toothpaste is effective in preventing tooth decay and cavities, leading to most toothpastes containing 1,000 to 1,100 mg/L of sodium fluoride or monofluorophosphate. 

However, recent findings challenge this notion. A study by Poznan University of Medical Sciences, involving 171 participants over 18 months, demonstrated that both hydroxyapatite and fluoridated toothpastes are equally effective in preventing cavities.

Is it better to have fluoride free toothpaste?

Whether fluoride-free toothpaste is better depends on individual needs and preferences. Fluoride was proven effective in preventing tooth decay and strengthening enamel, so it’s often recommended for people at high risk of cavities. 

However, a recent study showed that both hydroxyapatite and fluoridated toothpastes are equally effective in preventing cavities.

What happens when you stop using fluoride toothpaste?

Stopping the use of fluoride toothpaste may lead to a higher risk of cavities, especially if you’re not getting fluoride from other sources like drinking water. Fluoride helps to remineralize tooth enamel and prevent decay.

Which brand of toothpaste has no fluoride?

Several brands offer fluoride-free toothpaste options. Some popular ones include:

-Tom’s of Maine: They offer a range of fluoride-free toothpaste options.
-Hello: Known for their natural ingredients and flavors like watermelon and charcoal.
-Dr. Bronner’s: Offers organic fluoride-free toothpaste.
-Burt’s Bees: Known for their natural products, including fluoride-free toothpaste.
-Jason: Offers a variety of fluoride-free options.

Hazardous Ingredients You Should Avoid In Toothpaste

1. Sodium Lauryl Sulfate or SLS
Essentially used as a surfactant (which allows the substances in the formulation to blending correctly), Sodium Lauryl Sulfate is a well-known irritant.  Scientists have known about it for decades, their publications designated it as “the standard irritant”. The substance is also frequently used to induce “experimental contact dermatitis”. According to Dr. Talbot, SLS is present in 85% of toothpaste.

2. Triclosan
This powerful antibacterial agent was still widely used a few years ago. Since then, it has been shown to be an endocrine disruptor in many ways: it would not only act on estrogen hormones but also on thyroid function. 

3. Isobutyl, Isopropyl, Benzyl, Pentyl, Phenylparaben
Parabens are preservatives considered to be endocrine disruptors.
Not all parabens are bad though. Ethylparaben and Methylparaben are considered safe.

4. Titanium Dioxide
There are concerns about the toxicity of this substance, especially in toothpastes and lipsticks where there is a risk to ingest it.
