When using toothpaste, many people will prefer a certain fragrance or brand, and rarely change the brand. However, this habit is not worth promoting. If you use the same toothpaste for a long time, the bacteria in the mouth will develop resistance and learn to “resist” the effect of toothpaste to clean the mouth.

Humans deal with bacteria all the time, including those in the mouth. About 80% of toothpaste on the market has added certain drugs to prevent diseases such as dental caries and periodontal disease by inhibiting harmful bacteria. Among the medicated toothpaste, the most common ones are fluoride toothpaste and non-fluoride toothpaste, both of which should be changed regularly.

Fluoride toothpaste uses the active fluorine it contains to promote the remineralization of tooth enamel, which can better enhance the anti-caries ability of teeth. For people with more caries, this type of toothpaste should be used for a long time. Regularly choose two or three different brands of fluoride toothpaste to use alternately, and use their different anti-caries formulas to protect teeth in many ways, which is much better than the long-term use of the same brand of toothpaste.

Fluoride toothpaste and non fluoride toothpaste

Fluoride-free toothpaste should be used alternately in order to play a comprehensive oral health care effect. If the gums bleed frequently, you can use toothpaste with a hemostatic effect; if you have tooth sensitivity symptoms and are afraid of acid and cold, you can choose acid-proof toothpaste. After the above symptoms have disappeared, change to another type of toothpaste. This can not only prevent bacteria in the oral cavity from developing resistance to some medicinal ingredients but also prevent some ingredients from being used repeatedly for a long time and entering the human body too much.
