Toothpaste paste is jelly, the texture is more delicate and smooth with high-grade silicon as a friction agent, less wear and tear on the enamel; if the toothpaste in the mouth feel rough, need to rinse several times to remove, most of the friction agent contained in the rougher, long-term use of rough friction agent toothpaste brush teeth will be detrimental to teeth. 3, pay attention to whether it contains drugs. Drug toothpaste is favored by some people because of its unique function, and indeed the use of toothpaste to promote drugs with preventive or therapeutic effects is an ideal way.

The drugs in toothpaste are often placed for a long time and undergo other chemical changes, losing their original efficacy, and the effective drugs are often not suitable to be put into toothpaste because of the odor, in addition to the problem of drug resistance in the oral environment, all these factors indicate that the drug toothpaste should not be used for a long time, and it is recommended that the type of toothpaste can be changed frequently. Long-term use of the same drug toothpaste is likely to form changes in the oral micro-ecological environment.
