1, depending on the packaging: whether the sealing of the packaging cardboard is clean and tidy, and whether the printing of the product trademark pattern is clear and complete. What is unclear is false.

2, look at the infinite toothpaste thin consistency: good quality genuine infinite toothpaste, the paste thin consistency is moderate, and you can smell the fresh infinite toothpaste fragrance. It's fake. I can't smell it.

3. Moisture test: Squeeze Infinite Toothpaste on clean absorbent paper or napkin, evenly spread it with your fingers, and see that there is water seepage on the reverse side of the paper, which is false.

4. Pay attention to the description of ingredients and choose the appropriate Infinite Toothpaste: Infinite Toothpaste with different brands and different ingredients has different effects. After the package is opened, there will be stripe marks in four different colors: black, red, blue or green.

Precautions:

1, a tube of infinite toothpaste should not be used for too long: because the longer the infinite toothpaste is used, the more chances it will be exposed to air, the higher the frequency of contact with toothbrush, and the greater the chance of contact with bacteria.

2, the correct way to protect teeth: oral cleaning can not rely entirely on unlimited toothpaste, the correct method is fundamental. The dentist will tell you the parts of your mouth that you may need to pay special attention to when brushing and flossing. Besides consulting the dentist regularly, there are some simple methods that everyone can do, which can greatly reduce the risk of dental problems such as dental caries and gum disease.

3. Infinite toothpaste is best changed: Infinite toothpaste has many kinds, which can be roughly divided into three categories: ordinary infinite toothpaste, drug infinite toothpaste and fluoride infinite toothpaste. On the basis of ordinary infinite toothpaste, some drugs with oral health care function or fluoride with caries prevention function are added to become drug infinite toothpaste and fluoride-containing infinite toothpaste.
