It is usually in a synthetic form, namely hydrofluorosilisic acid. This molecule is non-compatible with the natural human biochemical pathways, and not only does it not affect tooth density or structure. It is highly toxic to the body in small, chronic doses, and is shown to numb the senses and render an individual docile, perhaps shedding light on the systematic fluoridation of nazi concentration camps.

Fluoride has a negative charge, and being in fact the most electronegative element, it can readily create strong bonds with many molecules. In our teeth we have calcium and phosphorous crystalline deposits around living connective and vascular tissue. Fluoride, when naturally present in fruits and vegetables as iron fluorine is harmless. It is is trace amounts, as it is a trace mineral, and in organic molecular structure. It is in accord with the biochemical mechanism of our bodies.

Also prevalent in toothpastes are sodium lauryl sulfate and sodium laureth sulfate, both of which are harmful to humans. MSG is also present in some toothpastes, and it bears many different names, and can be hidden even in the more ‘natural’ toothpastes. MSG is an excitotoxin, and it can do severe damage to neurons if consumed even on occasion. Triclosan is a very popular ingredient in main-brand toothpastes, and it too can cross the blood-brain-barrier and cause oxidative damage. It has been proven to be toxic to the immune system and a potent agent in the generation of harmful ROS.

Essentially, fluoride is not the sole perpetrator in the sheer toxicity of the most commonly used toothpastes. These are all loaded with carcinogenic compounds like artificial colors, heavy metals, and petroleum-based synthetic acid-forming substances. Coconut oil has the same strength and efficacy as chlorhexidine in eliminating S. mutans (bacteria that causes bad breath) growth. Activated charcoal and diatomaceous earth are incredible at adsorbing harmful acid-forming microbes (positively charged ((H+)) ) and leaving the alkaline-forming microbes that we need for a healthy buccal mucosa alive, as they are generally negatively charged and thrive best in an alkaline medium. Alkalinity is a function of electrolytic charge and balance.

Thus, for a healthy mouth pH and microflora, it is imperative that we apply non-intrusive and non-toxic means of oral hygiene. Additionally, a diet consisting mostly of raw fruits, melons, berries, vegetable juices, and the occasional tuber, alkaline grain, or phytate-low legume (black beans, lentils, etc) and cooked cruciferous veggies! Health begins in the mouth.

  • Pineal gland: A structural and functional enigma.
  • The presence of all enzymes needed for the synthesis of di-methyl-tryptamine (DMT) in pineal gland explains the near death experience (NDE) phenomenon. The various audio-visual hallucinations in NDE phenomenon occur due to massive increase of DMT in pineal gland before death. A very high concentration of di-methyl-tryptamine (DMT), presence of retinal proteins in 5–10% of pinealocytes, its role in thermoregulation and a possible role as magnetoreceptor in blind men and highest deposits of fluoride in the body are not only interesting but significant for the future research.

  • Interplay of glia activation and oxidative stress formation in fluoride and aluminium exposure.
  • Aluminium, fluoride and a combination of aluminium-fluoride treatments caused an increase in brain lipid peroxidation products and reactive oxygen species (ROS) formation. Similarly, an increase in glial activation and inflammatory response were seen in these groups versus the control. Oxidative stress induced glial activation (GFAP) and increased the expression of B cells (CD20). This also corresponded to the extent of tissue damage and lipid peroxidation observed. Taken together, the results suggest a close link between oxidative stress neuroinflamation and degeneration in aluminium-fluoride toxicity.

  • Fluoride exposure impairs glucose tolerance via decreased insulin expression and oxidative stress.
  • However, oxidative stress evaluated by the functional activity of superoxide dismutase (SOD) and generation of the superoxide anion (O(2)(-)), showed significantly decreased SOD activity, in a dose-dependent manner. This was accompanied by an increase in the generation of O(2)(-), and decreased mitochondrial membrane potential in F(-) exposed cells. Insulin secretion was lower in beta-cells exposed to F(-), even in the presence of glibenclamide, the ATP-sensitive K(+) (K(ATP)) channel blocker, suggesting down-regulation of the K(ATP) channel in the cell. Exposure to high levels of F(-) in drinking water may decrease insulin mRNA and its secretion from beta-cells, and might therefore affect the OGTT.

  • Fluorine–a current literature review. An NRC and ATSDR based review of safety standards for exposure to fluorine and fluorides.
  • Due to its insatiable appetite for calcium, fluorine and fluorides likely represent a form of chemistry that is incompatible with biological tissues and organ system functions. Based on an analysis of the affects of fluoride demonstrated consistently in the literature, safe levels have not been determined nor standardized. Mounting evidence presents conflicting value to its presence in biological settings and applications. Evidence examined in this review of the literature, and specifically the recent report by the National Research Council (NRC), offer strong support for an immediate reconsideration concerning risk vs benefit. Consensus recommendations from several sources are presented.

  • Fluoride- and electromagnetic radiation-induced genotoxicity and impaired melatonin secretion
  • Some animal and human work also suggests that fluoride (F) can impair the defensive response to genotoxicity by being deposited in high concentrations in the pineal gland and, through an enzyme-inhibiting action, reducing the secretion of melatonin, a powerful antioxidant able to eliminate free radicals and protect DNA. In having the capacity to be both genotoxic and impair melatonin secretion, F is similar to electromagnetic radiation, at power line frequencies and above, and both have very low or zero thresholds for causing toxicity. In view of the seriousness of neoplasia, the effect of fluoride on melatonin secretion warrants further research.

In general, hydroxyl groups increase both activity and cytotoxicity and the presence of the double bond in the side chain is not decisive for cytotoxicity and anti-protozoal activity.

  • Evaluation of triclosan in the Hershberger and H295R steroidogenesis assays.
  • In the H295R assay, TCS from 0.01 to 10 μM had no effect on testosterone production but TCS at 3 μM and above did induce a significant increase in estrogen production. At 10 μM, TCS produced significant cytotoxicity which confounded the interpretation of the estrogenic effect at that concentration. Thus, TCS had no effect on androgen synthesis or activity in the models used, but did enhance estrogen production and suppress serum T4.

  • Research Progress on Toxic Effects and Water Quality Criteria of Triclosan.
  • TCS can exhibit acute toxicity to aquatic organisms, affect the normal expression and physiological function of enzymes and genes, and produce cytotoxicity. Many studies have demonstrated that TCS exerts significant endocrine-disrupting effects on organisms, interfering the normal physiological functions of the reproductive, thyroid, and nervous systems via related signaling pathways. Moreover, we reported current research on the water quality criteria of TCS and discuss possible future research directions.

  • Amounts of fluoride in self-administered dental products: safety considerations for children.
  • Frequent ingestion of low but excessive quantities of fluoride during the period of tooth formation can lead to dental fluorosis. Particular concern is warranted for the ingestion of fluoride-containing toothpastes by young children and the inappropriate use of dietary fluoride supplements in communities with sufficient fluoride already present in drinking water.

  • Effects of the fluoride on the central nervous system.
  • The prolonged ingestion of F may cause significant damage to health and particularly to the nervous system. Therefore, it is important to be aware of this serious problem and avoid the use of toothpaste and items that contain F, particularly in children as they are more susceptible to the toxic effects of F.
