How to distinguish good toothpaste from bad

1. First of all, you should look at its consistency. If the toothpaste is very thin when squeezed, it means that there is a problem with the quality. You can also squeeze the toothpaste on toilet paper to see if there is water seepage on the paper. If there is serious water seepage, it means that the quality of the toothpaste is not good. Generally, good quality toothpaste rarely seeps water.

2. Judge by the appearance of the toothpaste. Generally, toothpaste is made through strict processing, and its toothpaste tube is cut uniformly by machine. Some toothpaste is uneven, has holes at the tail or no positioning lines, then this type of toothpaste may not be of good quality.

3. Identify the toothpaste based on its taste. A good toothpaste has a light fragrance. If you smell an unpleasant chemical smell as soon as you open it, then the toothpaste is definitely not up to standard.

Why can't you always use the same toothpaste?

You cannot use the same toothpaste for a long time: if you use the same toothpaste for a long time, the bacteria in your mouth will develop drug resistance and learn to "resist" the effect of toothpaste in cleaning your mouth.

Humans are dealing with bacteria all the time, including those in the mouth. About 80% of toothpastes on the market contain certain drugs to prevent diseases such as caries and periodontal disease by inhibiting harmful bacteria. Among medicated toothpastes, the most common are fluoride toothpaste and non-fluoride toothpaste. Both types of toothpaste should be changed regularly.

How to choose the best toothpaste

1. If your teeth are yellow, look for silicone. Toothpaste containing silicone has a good wear resistance coefficient, which can whiten teeth while minimizing the wear on teeth.

2. To prevent tooth decay, look for fluoride. Fluoride toothpaste refers to toothpaste containing fluoride. Scientists have found that fluoride can effectively prevent tooth decay. For children, especially those under 6 years old, it is important to prevent excessive fluoride intake.

3. For sensitive teeth, look for strontium chloride or potassium nitrate. Toothpaste contains desensitizing ingredients such as potassium nitrate or strontium chloride, which have a certain effect on allergic reactions to dentin. People with sensitive dentin can choose this kind of toothpaste.

4. To prevent dental plaque, look for "pyrophosphate" or "zinc citrate". This type of toothpaste uses the principle of friction and chemical bleaching to remove stains on the surface of teeth, preventing dental plaque and whitening teeth.

5. Salt is good for reducing inflammation. Salt itself has antibacterial and anti-inflammatory effects, so toothpaste containing salt is suitable for most people.
