Can We Use Regular Toothpaste to Remove Scratches?
The truth behind one of the most widespread myths in the world of phone repair
Introduction: The Big Toothpaste Myth
How many times have you heard or read online the phrase: "Put toothpaste on your phone screen and the scratches will disappear!" This “magic” method has been circulating for years on forums, YouTube videos and online articles, promising a quick and cheap solution to the problem of scratches on your smartphone screen.
But what actually happens? Is it really possible that a product designed for our teeth can repair the complex surface of a modern smartphone screen? In this article, we will scientifically examine this myth and explain why a professional approach is the only safe solution.
Scientific Analysis: Why Doesn't Toothpaste Work?
The Chemical Composition of Toothpaste
Toothpaste contains mild abrasive materials such as baking soda (sodium bicarbonate) or hydrated silica. These ingredients are designed to remove plaque from teeth, which have a completely different composition and structure from the Gorilla Glass found on modern smartphones.
Key Differences
- Hardness: Gorilla Glass has a hardness of 5.5-6.5 on the Mohs scale, while toothpaste abrasives are only 2-3
- Chemical Composition: Glass is aluminosilicate, while toothpaste mainly contains carbonate and fluoride salts
- Surface Treatment: Screens have special coatings that toothpaste destroys
Experimental Evidence from Top Manufacturers
Xiaomi, one of the world's largest smartphone manufacturers, conducted an official experiment to debunk this myth. The result was crystal clear:
"Toothpaste is a polishing agent, but the microscopic particles it contains cannot effectively repair the glass material of a smartphone screen. Furthermore, toothpaste is an alkaline substance that can destroy the acid resistance of the oleophobic coating over time."
