But is it really effective?
The Beijing Youth Daily reporter's investigation found that some consumers said that not only did it have no effect after use, but also showed symptoms such as tooth acid, darkened gums, and atrophy.
In this regard, the dentist said that the whitening of such products is mainly achieved through peroxides, but there is no industry standard for the content of this substance. If the concentration is controlled below 10%, the bleaching effect will be mediocre; if you risk increasing the concentration, it is easy Damage to the soft tissues of the gums.

Beautiful teeth artifacts that have worked in 7 days are selling well on the Internet, including some celebrity "endorsement" products.
The Beijing Youth Daily has seen from the e-commerce platform that the price of this kind of dental artifact ranges from 30 yuan to 220 yuan per box, and there are also recommendations such as "the same style of celebrity recommendation" on the sales pages of many stores.
The reporter of Beiqing Daily noticed that Shuke and Crest have gradually become Internet celebrity products due to high sales. These two brands have also been listed in the top two of the "high-end teeth whitening and decolorizing agent list" and are designated as "preferred top products" and " Popular Goods".
In the display window of an e-commerce platform, the prices of these two tooth whitening pastes are both one and two hundred yuan per box.
Although the price is not low, the sales volume is considerable. The monthly sales of Shuke are more than 10,000, and the monthly sales of Crest Whitening Teeth are more than 6,000.
In the comment area, some buyers reported that the macula on the teeth really faded, and some people claimed that the teeth were indeed white by two shades.
However, some people said that although there are some effects, it is not as white as the advertisements show.
Someone's teeth haven't turned white and become sensitive after using
The immediate effect, simple operation, and celebrity-recommended internet celebrity products have indeed attracted many fans eager to try.
Yueyue, who was a graduate student at a university in Beijing, told a reporter from Beijing Youth Daily about her after-use experience.
During the winter vacation last year, I finally chose Crest Whitening Teeth through a strategy.
In her impression, she felt that the product was not very expensive, so she started with 28 stickers.
At the beginning, one post every day, 40 minutes each time, and one post every other day afterwards, all in strict accordance with the requirements.
Yueyue learned from the comments of netizens that using this dental paste may cause toothache and even damage tooth enamel.
As for the principle of whitening, Yueyue speculated, “Because if the teeth are to be white, the protective film on the outside of the teeth must be corroded a bit.” And the customer service also explained to her, “As long as it does not stick to the gums, it will do.”
Yue Yue, who had been mentally prepared for a long time, planned to stop using it if his teeth felt sore.
Fortunately, the adverse reactions of dental acid did not appear, but after more than ten days of pasting, there was no effect.
Different from Yueyue, Xiaoqi followed the instructions for a week. Not only did her teeth not turn white, but her teeth became sensitive. "It feels very uncomfortable to stick on the teeth. At that time, the product said it was effective in 7 days, but there was no effect. Second After 7 days, I didn’t insist on sticking it every day. It’s not as effective as an electric toothbrush.” Xiaoqi described it as the feeling after eating a lot of sour food. The teeth became soft and astringent.
The reporter of Beiqing Daily also noticed that among the complaints of the consumer service platform Black Cat, there are many complaint posts related to tooth whitening stickers.
Among them, on December 26, 2020, some netizens complained that after using the Shuke brand of toothpaste, they had symptoms of gingival recession and tooth sensitivity.
The netizen said that he bought it because he trusted the recommendation of the anchor, and the merchant did not indicate that the product would cause damage to the gums. The customer service did not respond positively during the consultation, only that the product had a safety mark.
The customer service is vague about the effective ingredients of the whitening toothpaste
What are the effective ingredients of tooth whitening paste?
Is there a whitening effect?
What are the side effects?
In this regard, a reporter from the Beijing Youth Daily consulted the customer service of 7 of the shops selling tooth whitening pastes.
They all said that the results can be seen in about a week, but the reporter did not see the introduction and labeling of the relevant active ingredients and content in the product display map and the details page, and the explanations of the customer service were also vague.
Among them, Shuke customer service revealed that the content of hydrogen peroxide, the main ingredient in the product, was 0.3%; however, Crest customer service refused to provide it on the grounds of exclusive formula and safety testing.
It is worth noting that the customer service of the two brands of Shuke admit that the product will cause tooth acid reaction, but they promise that it will not damage the teeth, the product is safe and effective, and claim that it can be effective within 7 days, but children and pregnant women are not recommended to use it. .
Whether the peroxide concentration reaches 10% is the key
What is the principle of tooth stick whitening that is highly respected by everyone?
Do I need to whiten my teeth?
In this regard, Xu Yonggang, deputy chief physician of Xiaogan Central Hospital in Hubei Province, told the reporter of Beiqing Daily that the principle of whitening tooth paste is to use peroxide to decompose the pigment on the tooth surface to achieve whitening. It is similar to the principle of “cold light whitening” in dentistry, but it produces effects. The gap is huge.
Compared with "cold light whitening", the peroxide concentration in the tooth paste is lower, which is basically ineffective against endogenous tooth yellow, and the effect of exogenous tooth yellow has great selectivity. Therefore, in the feedback of online users, it is effective and ineffective. Both voices are loud.
"The'cold light whitening' in dentistry has technical parameters and indicators, and there are no indicators for non-dental as civilian use." Xu Yonggang said that there is no industry standard for this bleaching product, and there are still some dead spots, such as peroxide The concentration of the substance is controlled below 10%, and the bleaching effect is mediocre; if you risk increasing the concentration, it is easy to damage the soft tissues of the gums.
There are also some indications for selection. The young permanent dental pulp angle is high and easy to damage the dental nerve; patients with gingival recession or tooth hypersensitivity are likely to make the original symptoms worse.
"Even if there is a whitening effect, it will basically rebound after a year or less."
He emphasized that there are endless varieties of different brands of tooth pastes in China, and celebrity endorsements are so loud that some products are not peroxides, and many products have acidic pH and have not undergone rigorous experimental verification, so they are not recommended.

Businesses must be vigilant about the risk of tooth injury due to excessive exaggeration
Wu Bin, an attending physician at the Department of Stomatology, Beijing Luhe Hospital affiliated to Capital Medical University, said that even the products with the Xiaozihao need to be marked with the ingredients and content of the product, otherwise it is a violation of regulations.
Teeth whitening needs to be selected under the guidance of professional doctors. Because the causes of tooth discoloration are different, specific assessments are needed to choose the most appropriate method. "Exaggerated effects are all false advertisements. Things that affect the human body still require professional expertise. Professional institutions use professional equipment and professional knowledge to deal with it."
Xu Yonggang said that the yellow teeth in the eyes of many people tend to be a kind of heart disease.
In fact, most yellow teeth are normal yellowish, no need for whitening.
Some non-medical tooth whitening methods are using advertising and marketing to induce indiscriminately for all people. Some are pitted teeth, and some are pitted money.
The whitening effect is extremely exaggerated, the risk of tooth injury is not mentioned, and it has become a disaster.
So, what whitening methods are available in professional dentistry, are they more reliable than these? In this regard, Xu Yonggang believes that reliable and unreliable is only a relative concept, and the most important thing about dental whitening is that it can be applied to the crowd. It is necessary to make a real whitening effect, otherwise the patient will not be recognized for spending money; it is also necessary to prevent damage to the oral cavity, otherwise it will smash the sign. Due to these two prerequisites, dental whitening must first evaluate and screen the condition of the teeth. Therefore, many people who go to dentistry to request whitening will be directly rejected. This is a manifestation of industry norms and self-discipline, which is completely different from various whitening products. Of misuse and abuse.
