YOU may have heard of a useful hack that rubbing toothpaste on your smartphone screen can remove scratches.
It’s the kind of thing that’s been shared on TikTok and other sites for years.
These videos usually claim it fills in the dents and leaves a nice shine.
But according to experts, it’s just not true.
And it might actually do more harm than good.
Toothpaste is, of course, a polishing agent, but it is not strong enough to effectively repair damage such as scratches on glass.
As Xiaomi explains in a YouTube videoapplying toothpaste to a smartphone, whether iPhone or Android, can cause further damage.
“The microscopic particles inside cannot effectively repair the glass material of our smartphone screen,” the company says.
“In fact, toothpaste is an alkaline substance that can destroy the acid resistance of the oleophobic coating over time.
So if your phone’s screen cracks, toothpaste can’t solve the problem.”

The oleophobic coating is an oil repellant that protects the screen and can help reduce fingerprints.
To properly repair scratches without making things worse, it’s probably best to contact your smartphone’s manufacturer.
Even if it won’t be cheap.
Apple, for example, has its own screen repair and replacement service, as do many other device manufacturers.
Xiaomi recommends its customers to check their after-sales service.
