Toothpaste is an indispensable item in our daily life. There are various kinds of toothpastes. Different toothpastes have different effects. Why are some toothpastes very cheap and some toothpastes are sold to dozens of pieces? What are the differences between toothpastes with different prices?
The toothpastes in the supermarket are divided into ordinary toothpastes, medicated toothpastes and fluoride toothpastes. The prices vary from several yuan to tens of yuan. Even the toothpastes with high prices account for a large proportion of the supermarket shelves. Let's see the differences between them.
In fact, no matter the toothpaste is cheap or expensive, its main ingredients are almost the same, the purpose is to help clean the teeth. Therefore, when we purchase toothpaste, we should not only look at the price, but think that the expensive toothpaste must be good. The expensive toothpaste is some additives, such as some anti allergy, hemostasis, whitening and other ingredients. The main ingredients of toothpaste are friction agents, which are common There are three kinds of friction agents: calcium carbonate, calcium hydrogen phosphate and calcium pyrophosphate. Among them, calcium carbonate has strong friction and is often used to clean tea stains and tobacco stains on teeth (smokers and tea lovers are right to recognize this).
Toothpaste mainly plays an auxiliary role, and brushing method is the most important, followed by toothbrush.
Now some people have turned all these things upside down. We must master the correct method of brushing teeth, stick to brushing teeth every morning and evening, brush teeth for at least 3 minutes each time, and form a good habit of mouthwash after meals. At present, there are various effective toothpastes on the market, but there are only three kinds that are really recognized by the Ministry of health: fluoride toothpastes, anti-inflammatory toothpastes and anti allergy toothpastes.
We can choose according to our own needs to maintain oral health. As long as we choose ordinary toothpaste, if you have tooth sensitivity problems, choose toothpaste containing potassium nitrate anti sensitive ingredients, which can alleviate the pain caused by tooth hypersensitivity; to prevent tooth decay, we can choose fluoride toothpaste, which can effectively prevent tooth decay.
Three mistakes of toothpaste
1. Whitening toothpaste enables you to have white teeth
The color of normal and healthy teeth is light yellow, which is the color of enamel. Although genetic diseases, environmental factors, infectious diseases and so on will affect the color of teeth, if we want to make the color of teeth reach the snow-white level shown in TV advertisements, it is basically impossible to use only household whitening products such as household whitening toothpastes, and even more impossible to use toothpastes with only a few minutes of action time.
2. It is best to brush the toothpaste directly without water
As mentioned above, surfactants and foaming agents play an auxiliary role in cleaning. Most of them need to be soluble in water to function. Therefore, it's not correct to brush toothpaste directly without water. Before brushing, drink a mouthful of water to moisten the mouth and spit it out, then brush your teeth normally.
3. Electric toothbrush is better than ordinary toothbrush
The secret to protecting your teeth is to choose the right toothpaste, learn the right way to brush your teeth and stick to it instead of buying an expensive toothbrush. Electric toothbrush is not more reliable than manual toothbrush. The key lies in correct brushing method and long-term adherence.
