On the Internet one can find a great deal of different information on the fluoride content of toothpastes. There are currents claiming a so-called "dental conspiracy", claiming that toothpaste manufacturers add more fluoride, which may have a detrimental effect on the functioning of our organism by disrupting enzyme processes in cells, inhibiting cell respiration, disrupting carbohydrate metabolism or even affecting hormone synthesis. While there is no denying that fluoride itself is a compound that has a corrosive effect that can directly cause necrosis, experts have a slightly different opinion on this substance contained in toothpaste. Dentists claim that the dose of fluoride contained in toothpaste poses no risk to us [1].

Effect of fluoride

The most important characteristics of fluoride are its properties of reducing the influence of carious bacteria and inhibiting demineralisation. Thanks to the fluoride contained in toothpastes, plaque build-up is significantly reduced and metabolic changes in bacterial cells are inhibited. In addition, with a constant fluoride concentration, the repositioning of mineral compounds lost through the action of acids becomes possible, making the teeth resistant to bacteria [2].

Recommendations

According to the recommendations of specialists, it is best to apply about 2 cm of paste at a time, as this is sufficient for a single use and, moreover, is a safe dose. With regard to children, there should be enough toothpaste on the toothbrush to resemble a pea. Furthermore, it is advisable to alternate between different toothpastes, particularly when it comes to children, as they are a group in whom strengthening with fluoride preparations is particularly advisable [1].

Severe tooth hypersensitivity

Hypersensitivity, i.e. pain occurring when eating hot or cold food, but also sweet or sour food, is a very significant problem in the population. Fluoride in cases of severe hypersensitivity has a soothing effect and helps to alleviate the pain, although in some cases fluoride alone is not sufficient: it is necessary to use toothpaste that contains potassium chloride [1].
