Toothpaste Without Fluoride - Is Fluoride Harmful To Our Teeth?

Everywhere we hear how important fluoride is in preventing tooth decay and the great effects it has on dental health. Toothpaste containing fluoride can be found in every drugstore, pharmacy and supermarket, but toothpaste without fluoride is also often on the shelf.

Why is there this alternative when fluoride is so important for dental health? Could it be that it is harmful?

We take a closer look at the miracle cure and find out whether toothpastes without fluoride are a sensible solution.


1. What is fluoride?

Fluoride is a natural mineral that appears in various layers of rock and is also found in some foods and in water.

In the 1930s it was observed how fluoride in drinking water could reduce the formation of caries. Two decades later, it began to be used as an additive in toothpaste.


2. How does fluoride work?

Fluoride contributes to our dental health in three ways. For this reason, almost every toothpaste advertises that it contains fluoride.


2.1 Antibacterial effect

Fluoride fights the bacteria in tooth enamel and thus reduces their production of harmful acids, which in turn lead to the development of tooth decay. Sodium monofluorophosphate, sodium fluoride and especially amine fluoride have proven to be particularly effective in their antibacterial effect.


2.2 hardening of the tooth enamel

Fluoride also helps harden the enamel, making it more resistant to acid attacks. In particular, when a new tooth breaks through the oral cavity, it absorbs minerals from the saliva in order to build up the tooth enamel. The fluoride ions are also absorbed and integrated into the tooth enamel, making it more resistant and stable.


2.3 Mineralization of the tooth enamel

When the tooth enamel is attacked by acids, it always loses certain mineral salts. This mineral loss is compensated for by calcium and phosphate ions from the saliva. The fluoride dissolves these ions from the saliva and thus makes them available for the remineralization of the tooth enamel. Reconstruction would not be so effective without fluoride.


3. Is fluoride dangerous or even toxic?

In fact, fluoride is harmful in large quantities and, in excessive doses, can become toxic and can lead to nausea, vomiting, or fluorosis.

However, experts give the all-clear and say that fluoride poisoning would not be noticeable at the earliest from an amount of 350 mg. That would correspond to the contents of three 75 ml toothpaste tubes. In Germany, the fluoride content of toothpastes is limited by law to 0.15% (0.05% for children).

With normal use, there is no risk whatsoever in the use of fluoride toothpastes. If you accidentally swallow something while brushing your teeth, don't worry.


4. Toothpaste without fluoride?

As we've found, fluoride has some distinct advantages. In addition to its antibacterial effect, it strengthens tooth enamel and contributes to its supply of minerals. Numerous scientific studies prove its effectiveness and recommend the daily use of toothpastes with fluoride.

However, there are few or no scientific studies on toothpastes without fluoride, which is why experts usually advise against their use. In some special cases, however, they are a serious alternative to toothpastes containing fluoride, e.g. for children.


5. How to choose the right toothpaste?

When choosing the right toothpaste, there are mainly 3 factors that count. The grinding power, the type and amount of fluoride and the intended use.

Grinding force

  • Grinding force is given with the RDA value
  • The higher the value, the greater the degree of grinding
  • A value between 40 and 80 is recommended


  • Recommended fluoride types: amine fluoride, sodium fluoride and sodium monofluorophosphate
  • The amount of fluoride is given in parts per million
  • Recommended amount in adults: 1,000 to 1,500 ppm
  • In children: a maximum of 500 ppm


  • Sensitive toothpastes for sensitive teeth
  • Toothpaste for caries protection
  • Toothpaste with a whitening effect
  • Periodontal disease prevention toothpastes

6. Toothpaste in the test

Öko-Test Foundation, etc. conduct comparative tests annually to identify the best toothpastes. You will be examined for your ingredients as well as the tolerance and effect.

  • Oral-B Professional Gums & Enamel Pro-Repair (test winner)
  • Elmex Sensitive soft white
  • Meridol toothpaste
  • Signal herbal freshness
  • Colgate Complete 8 Natural Herbs

7. Children's toothpaste without fluoride?

Baby teeth are particularly sensitive to excessive fluoride intake. It can lead to fluorosis, which can be seen as white spots on permanent teeth. To prevent this, the fluoride content in children's toothpaste is legally limited to 0.05%.

While experts agree that fluoride is essential for teeth from childhood onwards, there is still disagreement about the form in which it should be taken.

Pediatricians criticize that children often swallow toothpaste and that other harmful ingredients get into their stomachs. They therefore recommend fluoride tablets instead of children's toothpastes containing fluoride.

Under no circumstances should toothpastes containing fluoride and fluoride tablets be taken at the same time. In this case, fluorosis would be predestined.


8. Children's toothpaste without fluoride in the test

If you would like to listen to the advice of paediatricians and prefer to give your child fluoride tablets, we have listed 3 children's toothpastes that do not contain fluoride.

They were rated “very good” or “good” in the Öko-Test comparison test.

1. Logodent Fresh Kids organic mint tooth gel
2. Nenedent children's toothpaste without fluoride
3. Alverde children's tooth gel


9. Where can I buy fluoride-free toothpaste?

Toothpastes without fluoride can be bought as normal in any drugstore or pharmacy. There are also numerous online shops where you have a large selection of toothpastes without fluoride.



Fluoride is an essential part of dental care. It kills harmful bacteria and strengthens tooth enamel by remineralizing it. However, too large an amount leads to fluorosis, which can occur quickly, especially in children, as the milk teeth are particularly sensitive.

While adults should definitely use toothpastes that contain fluoride, children can also use toothpaste that does not contain fluoride. In this case, however, fluoride should be supplied in the form of tablets.
