Ms. Lin recently discovered that her 10-year-old daughter Xiaoqing has a decayed tooth with black spots and a small hole

Ms. Lin recently discovered that her 10-year-old daughter Xiaoqing has a decayed tooth with black spots and a small hole. I heard that there is a toothpaste that can repair dental cavities, so Ms. Lin spent a lot of money online to purchase several "dental cavity repair toothpaste".

But a few toothpaste tubes have all been used up, and daughter Xiaoqing's tooth hole has not been repaired yet. Instead, it has become even more serious, from one decayed tooth to four! Ms. Lin hurriedly took her daughter to the hospital for examination. After the examination, the doctor filled Xiao Qing's teeth and reminded Ms. Lin not to buy so-called dental cavity repair toothpaste. This toothpaste is useless for repairing dental cavities and is subject to intelligence tax. Ms. Lin only realized that she had been tricked.

As for the question of "whether toothpaste can repair dental cavities", the National Medical Products Administration once issued a document saying that toothpaste is not medicine and cannot cure diseases,Toothpaste does not have the effects of repairing dental cavities, promoting tooth growth, stabilizing tooth looseness, and promoting tooth regeneration.The main raw material of toothpaste is a friction agent, which achieves a cleaning effect by rubbing the teeth with the bristles of the toothbrush,It cannot treat oral diseases.

The National Medical Products Administration also said that dental caries is a very common oral disease. After dental caries occurs, the Tooth enamel surface begins to demineralize. This development process is irreversible and cannot be repaired by toothpaste.If long-term gum disease causes damage to gum tissue, it is necessary to undergo professional oral examination, diagnosis, and treatmentInstead of relying on so-called efficacy toothpaste.

I believe those who have bought toothpaste in the supermarket have found that there are really too many types of toothpaste on the market now, and the prices are also uneven. The cheap ones are priced at 5 yuan, while the expensive ones cost 25 yuan, and even 45 or 55 yuan. So the question arises, what is the difference between toothpaste priced at 5 yuan and toothpaste priced at 25 yuan? Is the more expensive the better?

The Beijing Consumers Association has conducted experiments on 64 types of toothpaste produced by 28 enterprises, with prices ranging from expensive to cheap, including ordinary toothpaste, fluoride toothpaste, Chinese herbal toothpaste, and other types. The experimental results showed that,Although these toothpastes have different prices, there is not much difference in quality.

So why is the price difference so significant?

1. Brand premium

Many people buy things based on brands and believe they are more reliable. The same goes for toothpaste, even if it is produced by the same manufacturer, there is a difference in price between large brands and branded toothpaste

2. Additional functions of toothpaste promotion

Some businesses add functional words such as "anti allergy, anti gum bleeding, and whitening" to their advertising slogans in order to create specific labels for their toothpaste. The accessory functions of these toothpastes can affect their prices.

3. Different friction agents

In addition to brand premium and additional features, different friction agents in toothpaste can also lead to different toothpaste prices. Friction agents containing calcium phosphate have less damage to teeth and are more commonly found in mid to high-end toothpastes, while friction agents containing calcium carbonate are harder and relatively cheaper.

However, in the final analysis, toothpaste still focuses on cleanliness,If your teeth are healthy, just choose regular toothpaste instead of spending expensive money on expensive ones.

Some businesses use additives to highlight the effectiveness of their "special toothpaste". However, these additives are likely to pose safety hazards. Toothpaste containing the following three ingredients carries a risk of cancer and requires increased vigilance.

1. Triclosan

A study published in the authoritative international academic journal Nature Communication said that the antibacterial agent triclosan (TCS) contained in some toothpastes may cause damage to the human intestinal tract, which may induce enteritis, and increase the incidence rate of related intestinal tumors! TCS can also interfere with the endocrine system, especially with a relatively significant impact on female sex hormones. Therefore, it is not recommended for pregnant, pregnant, lactating women and children to use toothpaste containing triclosan for a long time.

2. Titanium dioxide

Experts from the French National Institute of Agricultural Research pointed out that titanium dioxide, titanium dioxide nanomaterials, and other materials may affect human health, with 40% of animals frequently exposed to titanium dioxide experiencing precancerous lesions in the intestinal mucosa.

3. Benzalkonium chloride

Benzalkonium chloride will destroy the balance of intestinal flora, which is adverse to intestinal health. Studies have found that animals exposed to Benzalkonium chloride in low doses for a long time have a higher incidence of colitis and colon cancer.

So how do you usually choose toothpaste? Recognize these three points:

• Choose toothpaste containing fluoride: Using fluoride toothpaste to brush teeth can enhance the anti caries ability of teeth. It is recommended that the fluoride content should be above 0.1%. The common ingredients are Sodium fluoride and Sodium monofluorophosphate
• Try to choose toothpaste with small particles.It is recommended to choose products containing hydrated silica, with moderate hardness and less risk of tooth damage
• Select effective ingredients according to personal needs.Choose the desired toothpaste according to your oral condition. For example, if your teeth are sensitive, you can choose those containing Potassium nitrate and other ingredients

In short, the expectation of using toothpaste to repair dental cavities is not scientific, as cavities and cavities themselves are irreversible. In fact, there are a variety of toothpastes on the market that have similar effects, many of which are only at different prices. Not necessarily expensive ones are good, but suitable ones are good.
