The toothpaste you use every day may have hidden dangers? According to the report of people’s daily on May 2, an article reprinted on the official website of the General Administration of quality supervision, inspection and quarantine pointed out that the whitening toothpaste of six brands, including Zhonghua, Colgate, Heimei, crest, Negro and LiBai, was mixed with bleach sulfite and its analogues, which had health hazards after long-term use. This news not only made whitening toothpaste questioned, but also focused on the safety of other functional toothpaste. What kind of toothpaste is better and how to use it more safely and effectively? The reporter of life times consulted relevant experts.
It is understood that sulfite and its analogues are generally used in papermaking and other industrial fields. It is a substance that is explicitly prohibited in the mandatory national standard gb22115-2008 specifications for raw materials for toothpaste. However, in the routine inspection of toothpaste, there is no requirement for sulfite, so it is “hard to say” whether the toothpaste on the market contains sulfite. The China oral cleaning and care products industry association issued a statement saying that “according to the experimental details described in the relevant reports, the method for testing the whitening ingredients in whitening toothpaste has great uncertainty from the scientific principle”.
Regardless of the outcome of the incident, in the opinion of Professor Bi Liangjia, member of the periodontology group of the Chinese Stomatological Association, any whitening toothpaste has little effect. There are only two ways to whiten teeth, that is, to remove color spots on the tooth surface and to improve the brightness of the teeth themselves. The former needs to be treated in the hospital, and the latter needs to use whitening agents to oxidize and decompose dental stains. Although the bleach in whitening toothpaste can remove part of the color spots on the surface of teeth, it has no effect on the endogenous deep color spots of teeth. This is the reason why some consumers “even after brushing for three or four months, the color of teeth does not turn white”. Moreover, because the whiteness of teeth is related to enamel and dentin, the structure of Chinese teeth has determined that our teeth are white and yellow, which can not be changed by any expensive whitening toothpaste.
Experts said that in addition to being too fond of whitening toothpaste, people still have many misunderstandings in the process of using toothpaste. In order to clean teeth more effectively, it is best to follow the following points when choosing toothpaste.
most ordinary people choose fluoride toothpaste Ouyang Yong, deputy director of the Department of oral prevention of Guanghua Stomatological Hospital of Sun Yat sen University, said that at present, fluoride toothpaste commonly used in China accounts for about 70% of the toothpaste market. Consumers in high fluoride areas do not need to use fluoride toothpaste, but the fluoride concentration in water in many cities in China is relatively low, so it is still very necessary to promote the use of fluoride toothpaste in these areas. American dental care experts also agreed that fluoride toothpaste was the best choice for the general population. The test showed that brushing teeth twice a day with fluoride toothpaste reduced the risk of dental caries by 40%. However, Wang Weijian, director of the Prevention Department of Peking University stomatological hospital, reminded that teenagers and the elderly can use it more, while preschool children should use it with caution. Moreover, parents need help to avoid accidentally swallowing toothpaste. In the long run, it may cause excessive fluoride intake and form a potential threat of fluorosis.
functional toothpaste should be used with caution the Beijing Consumer Association issued a consumption warning that consumers without oral diseases and dental caries should not blindly choose functional toothpaste. In case of improper selection, side effects may occur. Chinese herbal toothpaste can reduce inflammation and inflammation, and has a certain effect on periodontal health care. However, if your gums bleed for a long time, you should go to the hospital for treatment. Don’t expect toothpaste to play a therapeutic role; Antiallergic toothpaste can alleviate tooth sensitivity, but its cleaning effect is not as good as that of ordinary toothpaste. Moreover, studies in the United States have found that triclosan contained in some toothpastes may interfere with the human immune system, thus inducing allergies, and it is not suitable for long-term use; Long term use of the pharmaceutical ingredients in medicated toothpaste will cause dysbacteriosis in the oral cavity, and some drugs may enter the intestinal tract; Long term use of calcium toothpaste may increase the concentration of calcium ions in the mouth and promote the formation of dental calculus; Salt toothpaste should be used with caution for patients with hypertension.
to prevent damage, select small particles Ding Xiaoyi, Deputy Secretary General of the Chinese Stomatological Association, said that when purchasing toothpaste, we mainly look at the quality of the friction agent. Aluminum hydroxide and calcium hydrogen phosphate are better, followed by silicon dioxide, and calcium carbonate is the lowest grade. In addition, the particles of various friction agents have different sizes, and the finer particles will cause less damage to the tooth surface.
I’ll buy two kinds, one in the morning and the other in the evening it is understood that in advanced countries in Europe and the United States, more than 80% of people will use toothpaste with different functions in the morning and evening to better protect their teeth. Professor Bi Liangjia said that the saliva secreted by the human oral cavity has a bactericidal function. During the day, the saliva secretion is 3-4 times that at night, which is easy to inhibit the production of bacteria. Moreover, if you eat too much during the day, food residues are easy to remain in the oral cavity. Therefore, you should choose toothpaste with good cleaning function and can remove foreign matters and abnormal taste; At night, when people are sleeping, salivary gland secretion is insufficient, and toothpaste with bacteriostatic and bactericidal functions should be used to prevent caries.
The size of the toothpaste squeeze soybeans is enough many people are affected by advertisements. When squeezing toothpaste, they like to squeeze a whole strip on their toothbrush. If they swallow it by mistake, it will accumulate over time and cause excessive fluoride intake. Fluorine is one of the essential elements of the human body. If the human body lacks fluorine, it will suffer from dental caries. However, if the body contains too much fluorine, it will also form fluorosed teeth and make the teeth brittle.
don’t dip your toothpaste in water, it will work well when most people brush their teeth, they will habitually wet their toothbrush before squeezing toothpaste. Experts believe that it is not advisable to wet the toothbrush before brushing, because it will easily cause foam and make people mistakenly think that they have cleaned their teeth. Toothpaste does not use foam to clean teeth, but relies on the cleaning ingredients inside and the friction between toothbrush and teeth. The finer the friction and the longer the time, the cleaner the brush will be.
