Sodium fluoride makes you mentally weak

In Germany, many babies are given "D-Fluoretten ®", a combination of fluoride and vitamin D. As soon as the first tooth has grown, many dentists advise using toothpaste enriched with fluoride. During the dental check-ups, high-dose fluoride gel is often used. In addition, there are fluoridated dental floss, fluoride-containing mouthwashes, fluoridated table salt, etc. Fluoride treatment is intended to prevent tooth decay. However, the type and scope are also controversial among experts.

Is long-term fluoride treatment really good for your health and that of your child? Are there any side effects or contraindications that you should be aware of before opting for such treatment? What does fluoride actually do in the body and with the tooth substance?

As experienced dentists who work on the basis of anthroposophic medicine, we would like to inform you about these questions and topics.

We know and experience that human teeth can develop caries. They then get holes which - if left untreated - ultimately lead to the loss of the diseased tooth. Above all, excess acids are held responsible for this occurrence. caused by oral bacteria during sugar utilization and attack the hard tooth coating (tooth enamel), which can partially dissolve and destroy it. Where the tooth enamel and the underlying dentin (dentin) have dissolved and its structures have disintegrated, the dreaded tooth hole (caries) occurs, which usually enlarges continuously so that the tooth rots.


What are teeth made of?

The tooth substance consists of many different mineral substances and is very similar to the bone substance. The main component is a lime salt, calcium phosphate, the phosphoric acid lime. The most chemically active salt-forming element is fluorine. The human metabolism needs the salts of this trace element so that the skeleton becomes sufficiently firm. Fluoride is sufficiently present in traces in all water and in all natural foods and does not have to be added to a sensible and varied diet. The calcium phosphate of the tooth substance chemically contains hydroxyl groups.
This makes it flexible and can change its strength. Where very small amounts of fluoride are stored, the lime substance is called calcium fluoride. This is almost insoluble.

It is a natural process that minerals are continuously released from the tooth surface and absorbed by the saliva. In the same way, under good conditions, minerals contained in saliva are stored back in the tooth surface and strengthen it (remineralization). This is like a "breathing process" that takes place in almost all living organs and tissues and is always a characteristic of life.

If there is additional fluoride in the saliva, the dissolved calcium phosphate is changed: Due to their extreme reactivity, fluorides displace the phosphate from the calcium, so that instead of calcium phosphate, the almost insoluble calcium fluoride is now deposited in the tooth surface. The enamel can therefore no longer adequately participate in the natural process of loosening and reattaching described. As a result, it loses its flexibility, becomes rigid, immobile and brittle.


Why, where and how does fluoride protect against tooth decay?

In the sixties it was found out in experiments that additional fluoride introduced into the human organism (sodium fluoride, tin fluoride, later amine fluoride) leads to the fact that, due to the extreme reactivity of the fluorine element, in the area of ​​bone and tooth formation forms more fluoroapatite. The chemical reaction should serve to artificially strengthen the tooth substance. However, this causes the calcium substance in bones and teeth to condense more and more - a process that basically means aging and the retreat of the living metabolism. What takes place naturally in bones and teeth (the human limestone framework) over the course of a long life - namely compression, aging, hardening, loss of elasticity - then happens with the additional administration of fluorides
from an early age. So take with continuous fluoride intake z. B. the fragility of bones, and - according to a large Chinese study 1 - the intelligence quotient (IQ) decreases. The liveliness and thus the adaptability of the child's organism are inhibited, right down to the ability to think and learn. In addition, fluorides also have an inhibitory effect on metabolic processes, in which z. B. Magnesium plays a role, which is unfavorable especially in the period in which the child should grow and prosper.

On the advice of the pediatric medical societies, fluorides are recommended and given internally (systemically) in tablet form for children from the 5th day of life in Germany. Due to the lack of scientific evidence that this early treatment actually has a positive effect on the teeth, and due to the knowledge that tooth decay is not a fluoride deficiency disease, the scientific professional societies of dentistry advise against the systemic administration of fluoride. Instead, they recommend, since September 2018 again in higher doses, starting with the eruption of the first milk tooth twice a day with a pea-sized amount of a fluoride-containing toothpaste with 500 ppm (0.5 mg fluoride on 1 g toothpaste) or with a rice-grain-sized amount of a fluoride-containing one Toothpaste with 1,000 ppm to externally fluoridate the enamel when brushing your teeth. From the age of two to six, a pea-sized amount of fluoride toothpaste containing 1,000 ppm should be used twice a day. However, since children can only actively spit out toothpaste from the age of 3–4, but this is not suitable for consumption, paediatricians again advise against this. A dilemma of conflicting recommendations from medical societies becomes apparent here!

Dental fluoridation is therefore not a medically necessary measure, but rather the stimulation of solidification processes to reduce caries, which, however, are largely irreversible and block out the lively interaction.


Can tooth fluoridation be harmful?

Why is enamel fluoridation still regarded as the gold standard for caries prophylaxis today? This may be due to the fact that the enamel (the hard coating visible in the mouth over the crown of the tooth) is considered "biologically dead". The enamel-forming cells are forever dead long before the tooth erupts into the oral cavity. Due to this fact, tooth enamel can no longer reproduce or reproduce biologically after its formation. This is a unique situation for human tissue. If one thinks that this biologically dead enamel could be artificially "improved" by storing "more stable" calcium fluoride, one is not doing justice to the human being. This reduces or blocks the "mineral breathing process" of the tooth surface. It is the person himself who, not only as a physical but also as a soul and spirit being, continuously "revives" the supposedly dead tooth enamel and brings it back into the human metabolic cycle. The saliva is the mediator here. The acid-base process determines the intensity of the de- and remineralization. This situation in turn is directly dependent on the current state of feeling and consciousness. Depending on mental activity or emotional commitment, our acid-base situation in the oral environment is different at any time and thus shapes the mineral breathing process on the tooth surface. This is a kind of "liveliness of a higher kind" that goes beyond the purely biological reproduction of cells and is unique to humans.

Understanding the origin of caries is crucial for assessing the use of fluoride on teeth. This is promoted by circumstances that affect the entire human organism. Today there is scientific consensus that tooth decay is a multifactorial event. The uniqueness of every person means that different teeth can be affected at different times. The condition of the teeth also provides information on the overall health situation of the person. Dental fluoridation initially hides these facts at first glance. We assume that fluoridation of the dentition, in which de- and remineralization are reduced, has negative repercussions on the entire human calcium metabolism. From holistic knowledge we know that everything that is done on a person's body also affects his soul and spirit. Small children and adolescents are particularly in sensitive development phases in which nothing is static and perfect, but liveliness and adaptability are required. People can only develop into freedom and a sense of responsibility if they keep themselves alive and adaptable. An intervention in the form of additional, artificial fluoridation seems to counteract this.

The danger of overdosing is now more than ever because there is now an extreme oversupply of artificial fluoride sources: Toothpastes, mouthwashes, dental floss, toothpicks, tooth varnishes, table salt, soft drinks, filling materials and, in some areas of the world, drinking water enriched with fluorides. Therefore, when considering dental fluoridation, it is fundamentally essential to carry out a fluoride history (i.e. a careful review of all possible sources of fluoride, which, however, turns out to be very difficult in practical life). As far as drinking water is concerned, the current fluoride content can be obtained from the municipal water supply company.

The human body only needs traces of fluoride for its healthy development. Therefore, an overdose is reached quickly, which can lead to the malfunctioning of the enamel-forming cells during the formation of the permanent tooth crowns in the child's jaw (approximately from the 1st to the 7th year of life). The externally visible results are irreversible tooth enamel damage, enamel build-up disorders, which can range from white or brown spots on the tooth surface to a complete lack of large areas of enamel. The currently valid recommendation for the maximum daily total fluoride intake (in the sense of additional fluoridation) is 0.25–0.5 mg for children and 1.0–1.4 mg for adults. In this context, it should be borne in mind that the wastewater is also increasingly polluted with these substances, which are not naturally degradable.


Anxiety is a bad advisor - recommendations for healthy teeth

The health of your teeth depends on many different factors. Therefore, it makes sense to be or become attentive to the most diverse levels of life and to behave accordingly. Healthy oral hygiene should be learned and practiced from an early age. It is important to brush your teeth regularly twice a day from the first tooth, especially thoroughly in the evening. The most important thing here is the mechanical removal of the existing plaque. Appropriate dental care finger cots or soft knobbed toothbrushes are suitable for very small children. Toothpaste is unnecessary in the first year of life. Natural products can be used from the age of 2. A variety of natural care products are available.

Diet has a major impact on dental health. It is important to eat varied and as unpolluted foods as possible (e.g. Demeter products). Good and careful chewing (e.g. a raw carrot) strengthens the teeth. Dairy products are good for the teeth, sugar in various forms (because of the intensive acid formation) is more harmful. Most damaging of all are the incessant "sweets". The mouth needs regular meal breaks, during which the saliva can break down the acid. If so, sweets should only be eaten after the main meal and not in between. This not only protects against tooth decay, but also against obesity. Constant drinking from feeding bottles - which is now common in all age groups - promotes tooth decay, as the neutralizing saliva is constantly washed away. Drinking should be tasteless, juice spritzers and sugary drinks should be avoided. Fresh raw vegetables (vegetables and fruit) should also be on the menu every day. This not only protects against tooth decay, but also against other diseases. If you have milk intolerance, please ask your doctor.

Anthroposophic medicine knows a wide range of medicinal support for the most diverse weak points in the tooth, mouth and jaw area. Feel free to ask your anthroposophic family doctor or dentist! Regular check-ups at the dentist always serve to visualize the current dental situation and also provide information about your general state of health. If you develop an interest in your teeth and the connection between them and the whole organism, the fear will subside and turn into a positive affection.
