Though the humble牙刷has been around—in some form or other—for5,000 years, the nylon-bristled toothbrush we use today was invented in 1938. No matter how much the oral hygiene instrument evolves over the years, one thing remains the same: It has a dirty job,躲开斑块freshening breath。然而,今天,有一个相对较新的装置,越来越受欢迎,承诺让你的刷毛有点清洁:牙刷消毒剂($11.95,, a device that works to reduce the bacteria on你的牙刷with either heat,UV光, or a combination of both, explainsDr. Sophya Morghem, a cosmetic dentist in San Francisco.

But do they really work? In a nutshell, yes—but they're not miracle workers. "学习显示紫外线牙刷消毒剂实际上是为了减少牙刷上的细菌和生物的数量,“Dr. Brian Harris, a cosmetic dentist in Pheonix, Arizona. "However, they do not eliminate living organisms entirely."

The Pros and Cons of a Toothbrush Sanitizer

重要的是要记住有一个消毒和消毒之间的差异。当你清洁,reducing the amount of bacteria on a surface, but you're not killing it all. When you sterilize, you're消除细菌entirely. Because a sanitizer can't completely sterilize your toothbrush, it won't leave it completely bacteria-free, explains Dr. Harris. And there are other, less expensive,清洁牙刷的方法。Instead of using a sanitizer, you can soak your toothbrush in an alcohol-based mouthwash for 20 minutes each day or run your brush through the dishwasher, saysMichaela Tozzi博士,是拉斯维加斯的化妆品牙医。

So, are they worth using? "A toothbrush sanitizer can to a great job of minimizing the amount of bacteria that resides on your toothbrush, and anything that's going to帮助减少有害细菌的存在在嘴里值得使用,“哈里斯博士说。
