How to Fix Cracked Phone Screen with Toothpaste

In today’s digital age, our smartphones have become an integral part of our lives, allowing us to connect, work, and entertain ourselves. However, accidents happen, and one of the most common mishaps is a cracked phone screen.

A cracked screen not only affects the functionality of the phone but also diminishes the overall user experience. A cracked phone screen can be frustrating and even potentially dangerous if left unrepaired. It impairs touch responsiveness, hampers readability, and compromises the aesthetics of our beloved devices.

While professional screen repairs can be costly, there is a popular DIY method that claims to fix cracked screens using toothpaste. In this article, we will explore the toothpaste method, its feasibility, step-by-step instructions, and alternative solutions for fixing cracked phone screens.

Fix Cracked Phone Screen with Toothpaste

Understanding the Toothpaste Method

The toothpaste method involves applying toothpaste to the cracked screen and letting it dry, with the belief that it can fill in the cracks and restore some functionality.

Toothpaste typically contains mild abrasives, such as baking soda, which can help buff out minor scratches and provide a temporary fix for certain types of cracks. However, it is crucial to understand the limitations and risks associated with this method.

Assessing the Feasibility

Before attempting to fix a cracked phone screen with toothpaste, it is important to determine whether the method is suitable for your specific situation. Toothpaste can potentially work for minor cracks, such as surface scratches or small hairline cracks.

However, for more severe damage, such as deep cracks or shattered screens, toothpaste is unlikely to provide a reliable or long-lasting solution. It is essential to assess the extent of the damage before proceeding with the toothpaste method.

Furthermore, it’s important to note that attempting to fix a cracked phone screen with toothpaste may void any existing warranties or insurance coverage on your device. Consider the potential risks and weigh them against the cost of professional repairs or screen replacements.

Preparing for Cracked Phone Repair with Toothpaste

Before applying toothpaste to your cracked phone screen, gather the necessary materials:

  • Soft microfiber cloth
  • Toothpaste (preferably white, non-gel formula)
  • Cotton swabs or a soft-bristle toothbrush
  • Clean water (optional).

To prepare the phone for repair, follow these steps:

  1. Power off the phone and remove any protective cases or screen protectors.
  2. Gently clean the screen using a soft microfiber cloth to remove any dirt or debris.
  3. If desired, lightly dampen the cloth with clean water and wipe the screen to ensure it is clean and free from smudges.

Applying Toothpaste to the Cracked Screen

Now that your phone is prepped, it’s time to apply the toothpaste to the cracked screen. Follow these steps carefully:

  1. Squeeze a small amount of toothpaste onto a clean cotton swab or soft-bristle toothbrush. Start with a pea-sized amount and add more if needed.
  2. Gently and evenly spread the toothpaste over the cracked areas of the screen.
  3. Use small, circular motions to rub the toothpaste into the cracks. Be gentle to avoid applying excessive pressure.
  4. Continue rubbing the toothpaste for a few minutes, ensuring it covers the entire cracked surface.

Letting the Toothpaste Settle

After applying toothpaste to the cracked screen, it’s important to let it settle and dry completely. Follow these guidelines:

  • Leave the toothpaste on the screen for at least 10 to 15 minutes, or as recommended by some DIY enthusiasts.
  • During this time, avoid using or touching your phone to prevent the toothpaste from smudging or causing further damage.
  • Find a safe place to keep your phone, ensuring it remains undisturbed while the toothpaste sets.

Wiping off the Toothpaste and Assessing the Results

Once the toothpaste has dried, it’s time to remove it from the screen and assess the results. Here’s what you should do:

  1. Take a clean, soft microfiber cloth and gently wipe away the dried toothpaste from the screen.
  2. Use circular motions and light pressure to ensure you remove all traces of toothpaste.
  3. Inspect the screen for any visible improvements. In some cases, minor scratches may appear less noticeable or hairline cracks may seem less prominent.
  4. However, it’s important to manage your expectations. The toothpaste method is unlikely to provide a permanent fix for significant cracks, and the results may vary.

Preventing Cracked Screens in the Future

Prevention is always better than cure when it comes to cracked phone screens. Here are some tips to help you avoid future mishaps:

  • Use a Protective Case: Invest in a sturdy phone case that provides shock absorption and helps cushion the impact in case of a drop or fall.
  • Apply a Screen Protector: Consider using a tempered glass or plastic screen protector to add an extra layer of protection against scratches and cracks.
  • Handle with Care: Treat your phone with care and avoid placing it in pockets with sharp objects or dropping it onto hard surfaces.
  • Avoid Extreme Temperatures: Exposing your phone to extreme heat or cold can lead to screen damage. Keep it away from direct sunlight, and avoid leaving it in a car on a hot day or in freezing temperatures.
  • Regularly Clean Your Screen: Use a soft microfiber cloth to remove fingerprints, dirt, and debris from your screen. Avoid using abrasive materials that could scratch the surface.


Dealing with a cracked phone screen can be frustrating, but the toothpaste method offers a potential DIY solution for minor cracks and scratches. While it may not be a permanent fix and has its limitations, it can serve as a temporary solution until you can seek professional repairs or explore alternative methods.

Remember to assess the feasibility of the toothpaste method based on the severity of the damage and consider the potential risks involved. It’s essential to follow the step-by-step instructions carefully and manage your expectations regarding the results.
