Quick Answer: How Long Do You Leave Toothpaste on a Cracked Screen

Can toothpaste really fix a cracked phone screen?

Using toothpaste on a cracked phone is one of the oldest DIY repair tricks in the book. Apply a small amount of toothpaste to a Q-tip, then rub it into the crack in a firm, circular motion – being careful not to get any paste into bezels or gaps between the screen and the phone’s shell.

What happens if you put toothpaste on a cracked screen?

Toothpaste is mildly abrasive and could, in the right conditions, remove the surface of the screen and make the scratches less visible. Unfortunately, it’s not abrasive enough to make any visible difference – at least to our eyes.
