Is it better to change toothpaste frequently or not? Why can't we always use the same toothpaste?

I usually use the same toothpaste all the time and I am too lazy to change brands. But I heard that using the same toothpaste all the time is bad for my teeth. Does that mean I should change brands of toothpaste? Why can't I always use the same toothpaste?

Changing toothpaste frequently is good for your teeth. Because using the same toothpaste for a long time will cause some bacteria in the mouth to develop drug resistance, just like some pathogens, which will reduce the effect of cleaning the mouth. Therefore, changing toothpaste frequently is good for cleaning the mouth and teeth.

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 bacteria 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.

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.

1. Kitchen decontamination

Toothpaste can be used to remove scale, grease and other stains on stoves, refrigerator exteriors, rubber strips inside refrigerators, and wooden cabinets in the kitchen.

2. Decontamination of tea utensils

When cups and kettles have been used for a long time, we will find a layer of yellow stains inside that cannot be washed off with water. At this time, toothpaste can come into play. It can be removed with one wash and can also be used to clean stains on water dispensers.

3. Bathroom decontamination

The dirt on the toilet and washbasin in the bathroom is the most difficult to clean, but it can be cleaned with toothpaste, and it will look and feel like new.

4. Repair magic

When there are scratches on the car window glass or fine scratches on the watch mirror, you can use toothpaste to repair it. Apply a little toothpaste to the scratch and wipe it repeatedly with a soft cloth to remove the scratch.

5. Relieve itching

When you are bitten by mosquitoes, it will be very itchy, but what should you do if you don’t have toilet water? You can apply toothpaste on the itchy area to relieve the itching. It can also be used to relieve itching of prickly heat.

6. Eliminate redness and swelling

When you are stung by a bee, it will itch and swell. We usually apply vegetable oil on the surface. If there is no vegetable oil, you can also apply toothpaste on the surface to eliminate the redness and swelling.
