Fluoride Facts: What Is Fluoride?

Fluoride is a widely distributed mineral that we absorb through food and water. It is not an essential nutrient; while it protects against cavities, an overdose can quickly lead to fluorosis or other health problems.

How Do You Absorb Fluoride?

Fluoride is omnipresent in our daily lives: toothpaste, tea, fish with bones, fluoridated salt, seafood, mineral water, grain products.

What Does Fluoride Do to Your Body?

Since 2015, the U.S. National Toxicology Program (NTP) has been investigating the effects of fluoride on neurotoxicity and endocrine disruption. The brain responds sensitively at 1–2 mg/l, the thyroid gland at 2–4 mg/l.

A toothbrush and a pea are placed on a bright, smooth surface as a symbol of the fact that fluoride toothpaste should only be applied in a pea-sized or rice grain-sized amount to prevent a fluoride overdose.

Why Is the Correct Dosage Important?

The correct toothpaste dosage not only protects against cavities but also prevents fluoride overdose. The official recommendation for fluoride toothpaste is: pea-sized. Studies show that parents use significantly more toothpaste.

Prevention: Without Fluoride – Without Risk

The addition of fluoride in toothpaste is particularly controversial for children under 6 years of age. Children in particular swallow a large portion of their toothpaste.

Risk-free dosage

The uncontrollable swallowing of fluoride toothpaste can be particularly harmful to children. Therefore, the common recommendation is to use a rice grain-sized amount of toothpaste.

An overdose can cause fluorosis.

With KAREX, swallowing toothpaste is no longer a risk. Swallowing the active ingredient BioHAP is completely safe and without risk.

Fluorosis Risk

Fluoroses are unsightly white spots on the teeth that are caused by excessive fluoride intake and remain for a lifetime.

While most children's toothpastes contain fluoride, KAREX toothpaste offers a modern alternative with BioHAP. This nature-inspired active ingredient works without fluoride and reduces the risk of fluorosis.

    Remineralization

    BioHAP repairs the enamel and remineralizes small lesions evenly down into the underlying layers of the tooth.
    In this way, BioHAP also protects against the development of new cavities.

    Protective layer

    The microcrystalline structure of BioHAP forms a protective layer on the tooth surface during dental care.
    Acids and bacteria cannot attack the enamel directly.

    Acid protection

    During bacterial acid attacks, BioHAP releases calcium, which maintains the healthy mineralization of the enamel and reduces the tooth-damaging acidic pH value in the oral cavity.

    Biofilm control

    The bacteria in the oral cavity are bound by BioHAP and prevented from forming a biofilm on the teeth – but not killed.
    In this way, BioHAP helps to keep the oral flora in its natural balance.

    High fluoride exposure during pregnancy can potentially increase the risk of neurological developmental disorders in the child. A recent study therefore recommends limiting fluoride during pregnancy in order to minimize the risk of such disorders.

FAQ: Answers to your questions

The use of fluoride in toothpaste is particularly controversial for children under 6 years of age. Children in particular swallow a large portion of the toothpaste.

Due to the intake of additional sources of fluoride (vitamin D supplements with fluoride, fluoridated salt, etc.), the risk of developing fluorosis (white spots on the teeth caused by increased fluoride intake) increases significantly. For example, the German Federal Institute for Risk Assessment points out that if a children’s toothpaste with 500 ppm fluoride is swallowed, just as much fluoride is ingested as, for instance, through fluoridated salt.

According to the new recommendations, the amount of swallowed fluoride can therefore double. The risk of fluorosis is significantly higher with toothpastes that have a higher fluoride content (from 1000 ppm).

KAREX relies on the tooth-related active ingredient Hydroxyapatite (BioHAP) in all products. When swallowed, it is simply dissolved in the stomach. Numerous studies confirm its effectiveness: Hydroxyapatite repairs enamel with every brushing, reduces bacterial adhesion, and thus provides effective protection against cavities.

Our tooth enamel consists almost entirely of Hydroxyapatite. That is why BioHAP (biomimetic Hydroxyapatite) is used as an active ingredient in oral care. The highly concentrated active ingredient also serves as a source of calcium and protects our teeth against bacterial acids. Numerous studies confirm the benefits of Hydroxyapatite in the field of oral care and prevention.

Numerous publications confirm the effectiveness of BioHAP in dental care. These include not only laboratory studies (in vitro) but also studies with test specimens under oral cavity conditions (in situ), as well as, in particular, clinical studies on patients (in vivo).
For more information, feel free to read the German short summary or the original study. You can get an overview of the large number of studies on Hydroxyapatite as an active ingredient in dental care by browsing our study database (usable without registration).

Due to hormonal changes, teeth and gums can become sensitive during pregnancy. In addition, there is an increased risk of cavities. Since increased fluoride intake during pregnancy and breastfeeding can have a negative effect on the child, it makes sense to avoid fluoride in dental care during this time.

MAMA KAREX Toothpaste is the ideal toothpaste for expectant or breastfeeding mothers. It works effectively against cavities and protects sensitive gums with BioHAP – without fluoride.
