Misunderstanding of toothpaste: squeezing too much will cause cancer

1: too much toothpaste may induce oral cancer

There are several active ingredients in toothpaste that are worrying. The chemical “sodium lauryl sulfate” widely used in toothpaste is believed to cause gastrointestinal diseases and liver poisoning, which will make the mouth more prone to ulceration and oral cancer. The abrasives in toothpaste are also thought to damage gums, making gums more vulnerable, so don’t squeeze too much when using toothpaste.

2: improper use of fluoride toothpaste can lead to dental fluorosis

Nowadays, the prevention of dental caries with fluoride toothpaste has long been deeply rooted in the hearts of the people. When it comes to oral health care, the first thing I think of must be fluoride toothpaste. However, experts pointed out that although fluoride toothpaste can effectively prevent and treat dental caries, it also has side effects, and improper use can lead to dental fluorosis. The limit between the caries prevention effect and toxicity of fluoride is very small. Excessive intake of fluoride will produce spots on teeth, which is called fluorosis, and most of the patients are children. This is because children’s swallowing control ability is not perfect, and there are many chances of swallowing fluoride toothpaste by mistake when brushing their teeth, resulting in increased fluoride intake. Since there are generally no instructions for use, applicable groups and dosage of toothpaste, adults and children share the same toothpaste, and there is a phenomenon that toothpaste fills the toothbrush as shown in the TV advertisement.

Experts remind consumers that it is best not to use fluoride toothpaste more than 1cm each time, and children should not use fluoride toothpaste, or use it cautiously under the guidance of parents. At the same time, fluorine is a highly toxic substance. If the human body absorbs too much, it will cause fluorosis. The state stipulates that the free fluorine in fluoride toothpaste should be between 400 and 1200 PM. It should be particularly noted that children before the age of 3-4 should not use fluoride toothpaste, because 1 / 8-1 / 4 of the toothpaste may be swallowed by them.

III: children should not use multi foam toothpaste

Children should not use multi foam toothpaste. Toothpaste can be divided into three types: more foam, medium foam and less foam. The amount of foam depends on its soap content. Multi bubble toothpaste has a high soap content, which is easy to irritate the oral mucosa in the mouth.

IV: using a single toothpaste in the morning and evening is harmful to oral health

The stomatologist suggested that toothpaste products should be used alternately according to the seasons and physical conditions, and products of the same brand or the same effect should not be used all the time. In advanced countries in Europe and the United States, more than 80% of consumers have separated the toothpaste they use in the morning from the toothpaste they use in the evening, and they also have the habit of checking their teeth regularly. Studies have shown that most oral problems are caused by bacteria, and saliva secreted by the human mouth itself has a bactericidal function; However, saliva secretion during the day is 3-4 times that at night, which is easy to inhibit the production of bacteria; When people are sleeping, salivary gland secretion is insufficient and the mouth is dry, which will lead to oral acidification and can not inhibit bacterial reproduction, thus causing various oral problems.

V: medicated toothpaste should not be used for a long time

At present, many kinds of medicated toothpastes, such as desensitization, anti-inflammatory and tooth protection, deodorization and hemostasis, have emerged as the times require. Their advertising is overwhelming. Many people regard medicated toothpastes as a panacea for the prevention and treatment of oral diseases. Medicated toothpastes are used regardless of whether they have dental diseases or not. This is inappropriate. Bacteria in the mouth are divided into pathogenic bacteria and non pathogenic bacteria. They restrict each other and maintain the “ecological balance” in the mouth.

The long-term use of medicated toothpaste with strong bactericidal power will not only make the pathogenic bacteria in the mouth resistant to drugs, but also inhibit and kill the normal bacteria in the mouth while inhibiting and killing the pathogenic bacteria, thus destroying the “ecological balance” in the mouth and causing new oral diseases and infections. In addition, some medicated toothpastes contain alkaloids and highly irritating substances. Long-term use will not only damage the delicate mucosa in the mouth, but also cause inflammation of the gums, mouth, tongue and other places due to long-term constant stimulation, resulting in gingivitis, stomatitis, glossitis, etc; People with allergic asthmatic cough will suffer from asthmatic cough and gastrointestinal discomfort due to the irritating odor of medicated toothpaste. Some medicated toothpaste also contains dye, which will pollute the tooth surface, tarnish the teeth and affect the beauty of the teeth after long-term use.

For people with oral diseases, it is better to use fluoride toothpaste and medicated toothpaste instead. For example, for middle-aged and old-age patients with both dental caries and periodontal disease, it is better to choose fluoride products and Chinese herbal medicine products for use sooner or later. For patients who are sensitive to cold and heat, it is better to choose acid proof products with anti dentin allergy and general fluorine-containing products.
