How much do you know about toothpaste? You often hear people say that you should use different toothpastes for the benefit of your teeth. Why should toothpaste be changed? Many people can't say for sure. Today, I will clarify it for you!
Things to know about toothpaste:
1. Is it necessary to use toothpaste with fluoride?
American dental health experts unanimously believe that it is best to choose toothpaste with fluoride.
Experiments have shown that brushing teeth with toothpaste containing fluoride twice a day reduces the risk of tooth decay by 40%.
In the opinion of Wang Weijian, head of the Prevention Department of the Peking University School of Stomatology, for people with healthy teeth, toothpaste with fluoride is not a necessary choice. Teenagers and the elderly can use it more, but preschool children should be cautious; and they need the help of parents to avoid accidentally swallowing toothpaste, which may lead to excessive fluoride intake.
2. What are the ingredients of toothpaste?
Toothpaste is composed of various inorganic and organic substances, including abrasives, detergents, binders, moisturizers, sweeteners, fragrances, etc.

But there is no need to worry, all the ingredients are safe.

It is precisely because the main component of toothpaste is abrasive that its basic function is to clean the oral cavity. Whitening, desensitizing, hemostatic, and other effects are auxiliary.

However, experts point out that this kind of toothpaste is only limited to removing external stains on teeth, such as "contamination" caused by long-term coffee drinking, tea drinking, and smoking;
It has no effect on deep internal stains caused by abnormal tooth development, such as tetracycline teeth and fluorosis.

It is recommended to use toothpastes with different functions and brands as much as possible to exert the various benefits of different toothpastes and maintain oral health.

Some toothpaste is transparent or semi-transparent gel-like, while others are white paste-like. Although the taste and texture of gel toothpaste and paste toothpaste are different, the cleaning effect is the same.
