How to Fill a Cracked Screen With Toothpaste

By Alice Godfrey

A tiny crack in a cellphone screen is not fatal to the LCD's integrity but it does distract the user. You can fill the crack in the screen with toothpaste to make it disappear. Common household supplies beyond the toothpaste will be needed, but no special tools.

Things You'll Need

  • Hand towel
  • Compressed air
  • Soft cloth
  • Cotton swab

Step 1

Place a hand towel on a table. Place the cellphone on the towel with the screen facing up. Blow off the screen with a burst of compressed air. Wipe the edges of the screen with a soft cloth to remove any dust that has gathered there. Blow the screen off again with the compressed air.

Step 2

Apply toothpaste to the end of the cotton swab. Wipe the excess toothpaste off the sides of the swab with your finger. Wash your finger with water.

Step 3

Hold the swab in your right hand. Hold the cellphone down with your left hand. Place the covered tip of the swab against the screen at the left side of the crack. Press down gently as you drag the tip across the length of the crack. Remove the tip once the other side of the crack is reached. Discard the swab.

Step 4

Wrap the soft cloth around the pinky finger of your right hand. Hold the cellphone down with your left hand. Place the covered tip of your pinky against the screen at the left side of the crack. Press down gently as you drag the covered tip of your pinky along the length of the crack. Remove your pinky from the screen once you reach the other side of the crack. Place the soft cloth aside.

Step 5

Inspect the screen to see if the crack is no longer visible. If you can still see the crack, repeat the entire procedure again starting with the application of the toothpaste to the swab and the swab to the screen.

Tips & Warnings

  • Do not use toothpaste with flavoring; this can scratch the screen further.
