Why is the effect of toothpaste not obvious?
Precisely because the main component of toothpaste is a friction agent, therefore its main function - cleansing the oral cavity, whitening, desensitization, hemostasis and other effects are auxiliary.
The shape of the friction particles of whitening toothpaste is more specific and more favorable for removing stubborn tooth stains, so the teeth whitening effect can be achieved to a certain extent.
But experts point out that this toothpaste is limited to removing exogenous tooth color stains such as "staining" of teeth such as long-term coffee, tea and smoking.
Tetracycline teeth, fluoride teeth and other deep endogenous stains caused by abnormal tooth development are not affected.
