Toothpaste and health

Toothpaste is often used to clean oral cavity with the material. But it has some questions we need to notice. If we do not pay attention these questions, it will affect our health. The research show that toothpaste contains many chemical substances, such as foaming agents, friction agents, adhesives, and perfume, antiseptic anti-bacterial drugs, these materials would make a chemical reaction after a long time. It will cause not only the deterioration, but also reduces ability of the decontamination and cleaning. In general, shelf life of toothpaste is about 10 months. If shelf life of toothpaste exceed this period, it is highly perishable. The allergic reactions will caused that people use toothpaste which is metamorphism.

In addition, lead ions will enter the toothpaste, if the store of toothpaste which is lead quality is too long. If toothpaste which is lead quality is used for long time, chronic lead poisoning may occur, and results in decline of nerve conduction, stagnation of mental development, recession of understanding.

Therefore, it should be noted the production date. It is not used, if shelf life of toothpaste exceeds 10 months.
