Fluoride in toothpaste

In recent years, most brands of toothpaste have added fluoride, which is said to help prevent tooth decay. In fact, so far, there is not enough scientific evidence to prove that fluoride can prevent tooth decay. On the contrary, there is already enough scientific evidence to prove that fluoride has a strong oxidative effect and is highly toxic. Excessive intake of fluoride may cause problems such as osteosclerosis, lipid metabolism disorders, glucose metabolism disorders, and the most serious ones may lead to Cancer and cranial nerve disorders. In animal experiments, the use of low-concentration fluoride solutions increased the incidence of melanoma from 12% to 100%; other studies have shown that fluoride can increase tumors.

Hydrogen fluoride is also used in the manufacture of dentures and sodium fluoride is used in the treatment of dental caries. In the past, fluoride (sodium fluoride) was added to tap water and toothpaste abroad in order to prevent tooth decay, but in fact, fluoride will cause more damage to teeth. Even so, fluoride is still widespread in the world.

Fluoride comes from the aluminum product industry.The country's aluminum industry, which is famous for its aluminum products, as well as an agricultural product company and a chemical company that produces a lot of fluoride, have come up with a good way to deal with waste in order to ensure their own interests. One of them is ocean disposal of waste, but they have found a more effective and bold way to mix that waste into drinking water, food, toothpaste or medicine, and let the public help to solve the problems.

Even if fluoride is indeed good for teeth, the foods we eat every day, from crackers to vegetable juices, already contain excess fluoride contamination. In addition, there is sufficient scientific evidence that fluoride causes tooth enamel (chronic fluorosis). There are so many data proving that fluorine affects human health. Today, there are still people who buy products containing this poison and stuff them into their mouths every day. They have to underestimate the brainwashing effect of advertising and the community of scientific benefit on the whole society.

Fluoride in toothpaste mainly exists in the form of sodium fluoride or sodium monofluorophosphate. In fact, as long as you carefully observe, most mainstream brands of toothpaste are marked with the value of fluoride content.

Choose a natural and effective toothpaste or a more natural approach.

Knowing this, if you still insist on brushing your teeth, thinking that you can only participate in social activities if you have brushed your teeth with toothpaste. You can carefully select toothpastes that do not contain chemical ingredients such as fluoride, foaming agents, active agents, chemical sweeteners, preservatives, etc., which are not only harmless to the human body, but also more friendly to the environment.

In fact, there are two most natural, greenest, safest, most effective and cheapest methods:

The first is sea salt : use a damp toothbrush to gently rub your teeth, which not only makes the teeth white and clean, but also clears the breath, leaving a new level of comfort.

The second is body fluid : (saliva, the most effective and powerful disinfectant): from morning to night, whenever you have time, remember the second is body fluid (saliva, the most effective and powerful disinfectant): from morning to night When you have time, remember to use your tongue instead of a toothbrush to brush your teeth and gums. It works better than any product. If you don't believe it, ask any conscientious dentist.

The third is to choose a good toothpaste : that does not contain fluoride and various harmful chemicals: it is currently available on the market, and you can look for it attentively.

Now, you can start trying it right away! !

The dangers of fluoride

Fluoride in nature mainly comes from volcanic eruptions, high-fluoride hot springs, arid soil, the weathering release of fluorine-containing rocks, and the burning of fossil fuels.

Fluoride can be distributed in the air or dissolved in water. Fluoride in the air is mainly divided into gaseous and granular solids. In addition, fluorine is contained in various tissues of the human body, but mainly accumulates in teeth and bones. Appropriate fluoride is necessary for the human body. Excessive fluoride is harmful to the human body. The lethal dose of sodium fluoride to a human is 6-12 grams. If drinking water contains 2.4-5 mg/L, skeletal fluorosis can occur.

harm to plants

Fluoride is very toxic to plants. Some plants can be damaged by exposure to air containing 1×10–12 fluoride for several weeks, and short-term exposure to high fluoride air can cause acute damage. Plants absorb fluorine in the air through the stomata of leaves, and dissolve in the water around the cell protoplasm; most of the soluble fluorine absorbed through the root system remains in the root system, and a small part is sent to the leaf tissue through the stem, and accumulates in the leaf tip or leaf margin . Fluorine absorbed by the plant body directly erodes sensitive tissues, causing acid damage. The typical symptoms of fluoride damage in plants are necrosis of leaf tips and leaf margins that develop to whole leaves and stems. The young leaves that are expanding are most vulnerable to fluoride, and fluoride has an inhibitory effect on the elongation of pollen tubes and affects plant growth and development.

Hazards to Human Health

Effects on human health The fluoride in the human body comes from drinking water, food and air, and adults consume about 1 to 1.5 mg of fluorine per day. Excessive intake can affect health. Almost all of the gaseous fluorine inhaled through the respiratory tract is absorbed by the lungs and enters the blood circulation, and fluorine dust can be deposited in the upper respiratory tract, bronchi and lung cells. Soluble fluoride is absorbed quickly, while insoluble fluoride is difficult to be absorbed by the body. More than half of the fluorine entering the body can be excreted, and the excretion route is mainly through the kidneys, followed by the intestines, and a small part through the sweat glands.

Fluorine has a strong affinity with calcium, and more than 90% of the fluorine in the body is accumulated in calcified tissues such as bones and teeth. Ingestion of large doses of soluble fluoride in a short period of time can cause acute poisoning. Inhalation of high concentrations of fluorine-containing gas through the respiratory tract can irritate the nose and upper respiratory tract, cause mucosal ulcers and upper respiratory tract inflammation, and in severe cases can cause chemical pneumonia, pulmonary edema and reactive asphyxia.

Chronic fluorosis is caused by the deposition of fluorine in the bone, which is called skeletal fluorosis, which is characterized by thickening of the bone, reduced toughness, rough surface, and narrowing of the bone cavity, accompanied by multiple exophytic osteophytes, which make the joints move. hindered. In severe cases, the limbs are deformed due to ligament calcification and are prone to fractures. Fluorine combines with calcium in teeth and deposits on the tooth surface, making the enamel on the tooth surface tarnished and the dentin fragile and easy to wear. Children's teeth are especially sensitive to fluoride as they grow. Effects on Animals The mechanism of fluoride damage to livestock is similar to that of human chronic poisoning. Bone fluorosis is the main characteristic of livestock damage. The development of young animals is affected due to the disorder of calcium and phosphorus metabolism, resulting in incomplete calcification of teeth and bones. Cattle have the worst tolerance to fluoride. Eating forages with high fluoride content, pacing cattle, and reducing the ability to work, and the milk production of dairy cows drops significantly. Silkworms are very sensitive to fluorine, and mulberry leaves contain high fluoride, which can cause silkworms to die or not form cocoons.

Back pain is sometimes not from the bones, but from chronic fluorosis.
