1. Don't blindly trust its efficacy: Toothpaste doesn't stay in your mouth long enough to be rinsed out, and some special toothpastes don't work quickly enough. If your teeth are healthy, regular toothpaste will suffice.
2. It's best to switch toothpastes: Using the same toothpaste for a long time can cause some harmful oral bacteria to develop antibiotic resistance, rendering the toothpaste ineffective in its sterilizing and protecting teeth. It's best to alternate between different toothpastes.
3. Don't use a tube of toothpaste for too long: The longer toothpaste is used, the more it's exposed to air and comes into contact with the toothbrush, significantly increasing its chances of coming into contact with bacteria.
4. Toothpaste cannot replace dental treatment: Toothpaste, as a dentifrice, can enhance the abrasive cleansing effect of brushing. To enhance this effect, certain medications are often added to toothpaste, such as fluoride toothpaste, chlorhexidine toothpaste, and herbal toothpaste. Choose the right toothpaste based on your individual needs. To improve tooth sensitivity, consider toothpastes containing stannous fluoride, potassium nitrate, or strontium chloride. Toothpaste isn't a panacea and shouldn't replace medical treatment. If you have an illness, you still need to seek treatment at a regular hospital.
5. Choose a toothpaste that suits you: When brushing your teeth, especially in the morning if you're in a rush to get to work, toothpaste often doesn't stay in your mouth long enough before being rinsed out. Therefore, some special toothpastes don't work quickly enough. If your teeth are healthy, a regular toothpaste will suffice.
6. Don't share the same toothpaste with your family: Every mouth harbors a variety of bacteria. Even diligent brushing can only reduce the bacteria on the tooth surface, not completely eliminate them. This is especially true in the spaces between the bristles, where bacteria can accumulate. If a family uses the same toothpaste, bacteria from everyone's mouth will accumulate at the tip of the tube and then be carried away by others' brushes. The more people use the same tube, the more bacteria accumulate at the tip, increasing the chance of bacterial transmission.
