Do you need to change toothpaste brands frequently? Is toothpaste corrosive?

Toothpaste is a product that helps us clean our teeth. We all know that there are many brands of toothpaste on the market, so many people often change brands. So should we change toothpaste brands frequently? Is toothpaste corrosive?

Do you need to change toothpaste brands frequently?

Change it frequently. It is best to use toothpastes with different effects alternately. If you use the same toothpaste for a long time, the bacteria in your mouth will develop resistance to it. Dentists often tell us that changing toothpaste every three months is good for your teeth. Although there are many kinds of traditional whitening toothpastes, their whitening ingredients are almost the same except for the different tastes and effects. For the sake of safety and hygiene, the oxidant content in whitening toothpaste is very low, so the whitening effect is generally not very obvious. Most toothpastes on the market are added with certain drugs, which can kill bacteria and inhibit bacteria and clean teeth. If you keep using the same toothpaste, it will cause oral bacteria to develop resistance, and the bactericidal and cleaning effects will become worse and worse. In addition, whitening toothpaste can only remove a very small amount of stains and exogenous pigments on the surface of the teeth. It has basically no effect on teeth with endogenous stains such as tetracycline teeth and fluorosis. Therefore, it is basically impossible to whiten teeth simply by toothpaste.

Is toothpaste corrosive?

Some toothpastes are corrosive, but not all toothpastes are corrosive, but whitening toothpastes contain a small amount of corrosive agents. Whitening toothpaste helps polish teeth and prevent tooth stains. If you want a better whitening effect, you can choose a toothpaste containing silicone ingredients. This silicone has a good wear resistance coefficient and can whiten teeth while minimizing the wear on teeth. Therefore, long-term use of the same toothpaste to brush teeth will cause some harmful oral bacteria to develop drug resistance and resistance, making the toothpaste lose its sterilization and tooth protection function. It is best to use several toothpastes alternately, which can prevent oral bacteria from developing drug resistance to certain medicinal ingredients and affecting the prevention and treatment effect, and can also prevent certain drugs from being repeatedly used for a long time and excessively ingested into the body. Therefore, using several toothpastes alternately is a wise choice. In addition, the bacteria on the teeth interact with foods such as sugars, and the acid produced will erode the tooth enamel, thus forming tooth decay. The American Dental Association recommends that if you want to prevent tooth decay, you should choose a toothpaste containing mineral fluoride, which can form a protective film on the surface of the teeth to resist acid erosion.

The main ingredients of toothpaste and their functions

1. Abrasives. They are used to enhance the friction and decontamination ability of toothpaste and polish the tooth surface. The abrasive should have a certain friction effect, but should not damage the tooth surface and periodontal tissue, nor react with the drugs in the toothpaste.

2. Cleansing agent. It has the function of reducing surface tension, and can penetrate and loosen the dirt on the tooth surface, making it emulsified or suspended, which can be easily washed off the tooth surface by a toothbrush and abrasives and spit out with mouthwash.

3. Wetting agent. Its main function is to prevent the paste from drying and hardening, keep the paste strip shiny, and lower the freezing point of the paste, so that the toothpaste can be used normally in cold areas.

4. Adhesive. Adhesive is the gum-based raw material for making toothpaste. It is a hydrophilic liquid that forms a viscous liquid through diffusion, expansion and water absorption, so that the various solid and liquid components of toothpaste can be evenly combined together to form a paste that can be stored for a long time, transported and used conveniently with stable performance.

5. Fragrance. It makes the person brushing his teeth feel refreshing and comfortable, and helps to reduce bad breath. The fragrance of toothpaste is an important indicator for consumers to choose which toothpaste to buy.

6. Drugs. In order to prevent and treat common oral diseases, certain drugs, such as fluoride and chemical fungicides, are added to toothpaste to prevent caries and periodontal diseases.
