It is likely that, on YouTube or even on Facebook, you have already come across a video that teaches you how to apply toothpaste on the broken screen of your cell phone, covering its scratches. Although it seems like a “precious tip”, Xiaomi has proven that this trick does not work – and worse: it can even be harmful to the device.
In a video published last Friday (9), on its YouTube page, Xiaomi shows a layer of toothpaste being spread on the display of a smartphone with several cracks on the screen.
While the procedure is being carried out, a voice explains that, according to the viral tip, the toothpaste would help to polish the scratches and fill in the dents on the surface of the braces. A change, however, that does not happen when the action is finished and the cream is removed.
According to the company, this happens because, even though toothpaste is a polishing agent, this characteristic is not enough to restore the microscopic interior of the cell phone screen glass. Which means that regardless of the amount, time or pressure applied in an operation like this, the toothpaste has no effect on the cracks and scratches of the device.
according to one article from CNETwho also performed the test and found that the phone just got brighter (without showing any change in screen scratches), the trick, however, works when applied to protective plastic skins on the cell phone.
In these situations, the cream actually seems to work quite well. Which may help explain why, even though it has no effect on smartphone screens, the “tip” is still replicated on the internet.
In addition, it is worth remembering that the false trick is also greatly fueled by content farms, which produce videos with fake thumbnails or even tests that do not correspond to reality.
Despite being misleading, these contents are attractive to the public and generate views by delivering an easy, quick and cheap “solution” to such a common problem.
Toothpaste is harmful to the cell phone screen
Another point raised by Xiaomi’s video is that, in addition to not bringing results, toothpaste applied to a smartphone screen can be harmful to the device.
According to the company, toothpaste is an alkaline substance that, over time, can destroy the oleophobic resistance layer of the cell phone screen. An essential coating to prevent fingerprints on your smartphone and the accumulation of even more stains on its surface.
Aside from her, anyone thinking of resorting to a test with sodium bicarbonate, a common ingredient in some toothpastes, may also give up on the idea. In this situation, the abrasive component of the material can work even more in reverse and cause more scratches on the device.
