1. Don't blindly believe in the effect: the toothpaste is rinsed out when it stays in the mouth for a short period of time, and some special toothpastes are difficult to exert their efficacy in a short period of time. If the teeth are healthy, use ordinary toothpaste.

2. Toothpaste is best to use: long-term use of the same toothpaste to brush your teeth will cause certain harmful oral bacteria to develop drug resistance and drug resistance, and the toothpaste will lose its sterilizing and protective role. It is best to use several toothpastes alternately.

3. Don't use a tube of toothpaste for too long: the longer the toothpaste is used, the more opportunities it will be exposed to the air, the higher the frequency of contact with the toothbrush, and the greater the chance of contact with bacteria.

4. Toothpaste is not a substitute for treating dental diseases: Toothpaste, as a kind of dentifrice, can strengthen the friction and cleansing effect of brushing teeth. In order to enhance the effect of brushing teeth, certain drugs are often added to toothpaste, such as fluoride toothpaste, chlorhexidine toothpaste, Chinese medicine toothpaste, etc., can be selected according to personal needs. To improve tooth sensitivity, toothpaste containing stannous fluoride, potassium nitrate, and strontium chloride can be used. Toothpaste is not a panacea and cannot replace treatment. If you have a disease, you need to go to a regular hospital for treatment.

5. Choose the toothpaste that suits you: When we brush our teeth, especially in the morning, if we are in a hurry at work, the toothpaste is often rinsed out if it stays in the mouth for a short time. Therefore, some special toothpastes are difficult to play in a short time. Effectiveness, in fact, if you have healthy teeth, you can use ordinary toothpaste.

6. Family members can’t use the same tube of toothpaste: because everyone’s mouth is an environment where there are many kinds of bacteria. If you brush your teeth carefully, it will only reduce the bacteria on the tooth surface. It is impossible to completely eliminate it, especially on the toothbrush bristles. There will be bacteria attached in the gap. If a family uses a tube of toothpaste, the bacteria in everyone’s mouth will accumulate in the mouth of the tube and then be taken away by someone else’s toothbrush. The more people use the same tube of toothpaste, the more bacteria will accumulate in the mouth of the toothpaste tube, and the higher the chance of bacteria spread.
