Step-by-step instructions for removing scratches

Step-by-step instructions for removing scratches

Step 1: Take toothpaste, towel and prepare the table

Toothpaste is an abrasive that may help you get rid of cracks on your phone display if they are quite slight. How does it work? As an abrasive, it fills the scratch and helps the pieces of glass stick together. In order to more effectively fix a cracked phone screen at home with toothpaste, we advise you to take a cotton towel or any soft cloth. Prepare a clean, flat surface – a stable table is the best choice.

Step 2: Put the phone on a towel with the screen facing you

In order to prevent the phone from moving on the surface of the table, you should put it on a towel with the screen up. A towel will also help to avoid soiling the table while repairing a cracked phone screen.

Step 3: Blow off the entire surface of the screen with compressed air

Before you begin to fix a broken phone screen with toothpaste, it’s important to clean its display. Use a can of compressed air to remove all dust and lint.

Step 4: Wipe the screen edges with a soft cloth

Dust or other debris may remain on the edges of the screen. Take a soft cloth and wipe them down. The fixing cracked phone screen process can go to waste if, for example, a lint appears in a crack on the side of the phone. The towel should be soft so as not to further damage existing scratches.

Squeeze some toothpaste onto the edges of a cotton swab. Then apply toothpaste to a cracked screen. Spread it evenly across the display. You need to rub the paste in a circular motion so that it fills all the scratches. Rub the paste on until they are no longer visible.

Step 6: Clean the sides of the screen of excess toothpaste

To remove excess toothpaste from your display, wipe the edges with a damp cloth. If it remains on the surface, the screen will be sticky.

Step 7: Press down neatly and gently so that the paste fills the entire crack

Use your fingers to apply a little pressure on the display so that the toothpaste will get into all the scratches. Don’t overdo it because you can damage your phone’s screen even more. And in this case, it will definitely not be possible to fix the phone screen with toothpaste.

Step 8: Check if the crack is still visible on the screen

Scratches on the phone should no longer be visible if you did everything carefully and if they were slight enough to be fixed this way. To better check the display, approach a natural light source. Evaluate the result of your work: if you missed a few scratches, repeat the procedure again. But if you still have severe scratches on your phone screen, you’d better take your device to the nearest service center.

Prevention of new cracks

The best way to prevent new scratches and cracks from appearing on your phone or iPad is to stick a screen protector on it. When your device falls, the protective surface will first break, and the display will be intact. In this case, you’ll never need to fix your phone screen with toothpaste. For more effective protection, buy a flip phone case or a bumper cover.


What toothpaste can be used to fix phone cracks?

You can use any toothpaste you have at home. There’s no particular brand that helps to fix cracks better than others. They all work the same way.

How does toothpaste remove screen scratches?

The miraculous effect of toothpaste in removing screen scratches is caused by fine abrasives. These special components are used to remove dental plaque and stains. They also make the surface smooth, which helps polish out small phone scratches.

Is toothpaste really effective in fixing cracked screens?

The effectiveness of toothpaste directly depends on the nature of the cracks on your screen. This method works well for polishing small, superficial scratches. But if the cracks are deep, toothpaste is unlikely to help you fix your screen.


When your device's screen breaks, it's important to keep it looking good. If the damage is minor, you can fix a cracked phone screen with toothpaste.

You will need improvised materials for the process - a towel, toothpaste, and a cotton swab. Also, use compressed air.

Toothpaste will successfully hide slight scratches: just rub it into the screen and remove the excess. Then check if all scratches are gone. In order to save the screen of the device, use covers for them and glue protective glasses.
