On the Safety of Stannous Fluoride
Stannous fluoride, among all kinds of materials, there are many opinions on its safety. To understand its details, it is necessary to investigate its properties and observe its use, and then it can be safe.

Stannous fluoride has unique chemical properties. In its chemical structure, tin and fluorine are combined, and then this bound state is in different situations, or it shows different properties. In normal conditions, its solids are still stable, but it encounters acid-base changes, temperature and humidity differences, or biochemical changes. If placed in the environment of strong acid, fluorine or segregation, tin is also in a different state of synthesis, which may involve changes in safety.

As for the use, tin fluoride is mostly used in daily products, especially tooth powder and toothpaste. In oral care, it claims to prevent caries and fix teeth. The properties of fluoride cover can be combined with the calcium and phosphorus of tooth enamel to form a stronger fluoroapatite, which increases the anti-caries power of teeth. However, if it is used too appropriately, there may be hidden concerns. The oral mucosa is delicate. If long-term high-concentration exposure to tin fluoride may cause mucosal discomfort, such as tingling and redness. And the concern of swallowing should not be ignored. Although toothpaste is rinsed out more after use, it is unavoidable to swallow a small amount. If it accumulates over time, the amount of fluoride in the body will gradually increase, or damage the bones and teeth, causing bone fluorosis and dental fluorosis.

Looking at the production process, it also involves safety. In the production room, workers often face stannous fluoride. If the protection is not good, the dust will be inhaled, or invade the lungs, hurting the respiratory system. And its storage, also need to be careful. Improper storage method, such as temperature and humidity loss, or deterioration, the safety of the changed thing is more difficult to measure.

In summary, stannous fluoride is not a decidedly safe thing. Use it reasonably, control its amount, and understand the method, which may be beneficial for oral care. However, negligent use or careless production storage can cause safety risks. Therefore, users and operators should pay attention to its safety, study it carefully and be cautious.
