Toothpaste cancer? Xiaobian teach you choose toothpaste

The news bombing of food safety issues just took a while to stop, and another "imported" thing has happened, toothpaste!

Recently, foreign media reported that the U.S. Food and Drug Administration and the U.S. Environmental Protection Agency are evaluating the safety of triclosan. Therefore, Weibo’s message that “Triclosan in toothpaste may cause cancer” is spreading wildly. Among them, Colgate's full effect and Crest's partial toothpastes have been reported to contain triclosan.

Can triclosan and carcinogenicity be equalized? This issue is still pending. Many toothpastes on the market marked with the addition of triclosan are still being sold.

Dr. Li Shuguang, Assistant Dean of Hangzhou Shengxicheng West Branch, said that triclosan, as a broad-spectrum antibacterial agent, is also very common in toothpaste, but some scientific studies in recent years have shown that it has some unknown human health. influences. So choose triclosan toothpaste should be careful.

Toothpaste is an indispensable daily necessities in our lives. What problems should we pay attention to in the selection process?

Nowadays, all kinds of toothpastes on the market are dazzling, homemade, and imported, and prices range from a few yuan to tens of dollars. The major brands of toothpaste have also advertised themselves to promote their perfect function, such as cleaning the mouth, eliminating bacteria, resisting inflammation, protecting teeth, etc. Faced with so many toothpaste brands, consumers need to have a certain understanding of toothpaste.

At present, the toothpaste used in China is mainly divided into three categories: ordinary toothpaste, fluoride toothpaste and medicinal toothpaste.

The main components of ordinary toothpastes include abrasives, cleansing agents, moisturizers, preservatives, and fragrances, and have the common function of toothpaste. If the dental health is better, ordinary toothpaste can be selected.

Fluoride toothpaste is a kind of toothpaste that is more common on the market. It adds a fluoride component on the basis of ordinary toothpaste. Fluoride has a role in preventing dental caries. It has been proved for many years that fluoride comes into contact with teeth and makes tooth tissue. Hydroxyapatite, which is easily dissolved by acid, forms insoluble fluoroapatite, which improves the corrosion resistance of the teeth. Studies have shown that the incidence of dental caries is reduced by about 40%. However, fluorine is double-sided. Fluorine is also a toxic substance. If the human body absorbs too much, it can cause fluorosis. According to the national regulations, the free fluorine of fluoride toothpaste should be between 400-1200 Pm. Special attention should be paid before 3-4 years old. Children should not be used because 1/8-1/4 toothpaste may be swallowed by them.

Drug toothpaste is based on ordinary toothpaste plus a certain drug, toothpaste reaches the tooth surface when brushing or teeth around the environment, through the role of drugs to reduce plaque, thus playing a role in preventing dental caries and periodontal disease. Many people now use drug-based toothpaste. Some people think that the drug-toothpaste is available to all people. It is disease-free, disease-free, disease-free, and harmless. In fact, this concept is wrong.

The use of drug toothpaste can treat some dental diseases. For example, those who suffer from dental caries or who are engaged in acid production for a long time can choose to use anti-flood toothpaste with anti-acid and anti-mite effects. People with periodontitis and gum bleeding can use it. Use anti-rust toothpaste or enzyme toothpaste; for some people suffering from allergic dental disease, desensitizing toothpaste can be used. However, if you do not choose the right toothpaste, not only can not achieve the intended purpose, but also have side effects.

The drug toothpaste contains more alkaloids or other spicy substances with strong irritation, such as the long-term use of antibacterial, anti-inflammatory, analgesic, and hemostatic toothpaste, will kill the pathogenic bacteria in the oral cavity and kill the normal bacteria at the same time. Extinguishes, causes the oral cavity to produce the new disease, and has the damage to the oral mucosa, may cause the gingivitis, the stomatitis, the glossitis and other inflammation, also may produce the chronic drug poisoning and the drug resistance in serious. The active pigment pigment contained in the drug toothpaste is good for contaminating the dental surface and affects the appearance of teeth. People who have allergic cough and use drug toothpaste can also cause nausea and wheezing and coughing that can affect appetite due to irritating odor.

In addition, we must pay attention to the medicines in toothpaste, which often take place due to other chemical changes and lose their original efficacy.

Therefore, in the face of numerous toothpaste varieties, consumers should first understand the properties of various toothpastes when choosing, and do not blindly believe in product descriptions. It is best to consult an oral professional doctor to select an appropriate toothpaste according to the actual conditions of their oral cavity.

Second, when purchasing toothpaste, besides choosing a brand, you should also pay attention to whether the fluorine content is excessive.

In addition, people who choose to use toothpaste containing a drug ingredient should pay attention to changing the type of toothpaste often to avoid misalignment of the oral flora.

Finally, look at the toothpaste ingredients. The name of the chemical structure of triclosan is trichlorohydroxydiphenyl ether. The English name is Triclosan. The common names are Klein, bacteriocin, triclosan, INN, BAN, USAN, etc. . If these words are found in the manual of toothpaste, they contain triclosan.
