Why disposable toothbrushes can only be used once,

First of all, the hotel's testing of toothbrushes is not as strict as that sold in the market, and because it is disposable, its antibacterial effect is definitely not many times better than that sold in the market. Moreover, it is probably accompanied by some other bacteria. What's more, this toothbrush is not designed for you personally, and it is likely to be inconsistent with your gums and teeth. For example, if you want to use soft hair, that root is hard hair, which will make your gums bleed and your roots grow.

Because these disposable toothbrush toiletries are hidden in various hotels, they are often ignored by the supervision. Compared with other daily products, there are few special inspections on these products. Therefore, the disposable toothbrush toiletries in the hotel have almost become a forgotten corner. But if you use it once or twice occasionally, that's fine. If you use it frequently, not only will the thick toothbrush make the gums crack and bleed, but the teeth will not be cleaned effectively, which will lead to oral diseases in the long run.
