Last Updated on August 5, 2023 By Emma W. Thomas

Using toothpaste to fix a cracked phone screen is not recommended. It may temporarily fill tiny scratches, but it won’t repair cracks. To fix a cracked screen, seek professional repair services or replace the screen altogether for a safe and effective solution.

Steps To Follow When Fixing A Cracked Screen Using Toothpaste

Follow these steps to repair a cracked phone screen using toothpaste;

  • Place the phone on a stand covered with a towel, with the phone screen facing upwards
  • A lot of compressed air blows over the whole screen. In this case, you can use a hair blow-drier.
  • Blowing air over the screen attracts dust. Use a clean and soft towel to wipe out the screen edges and then blow the screen with the edges’ compressed air.
  • Carefully apply a thick layer of toothpaste on a cotton swab. Remove the excess toothpaste running on the cotton swab sides using a finger to avoid blocking any phone’s opening with the toothpaste. Wash your hands immediately after using your fingers to wipe off the paste
  • With the cotton swab on the right side and the phone on the left hand, put the tip covered with paste on the screen from the left side that has the crack
  • Apply the paste gently on the phone such that the screen is completely covered with toothpaste
  • After the whole screen is fully covered with paste, gently remove the cotton swab and dispose of it
  • Allow the toothpaste to remain on the phone for a short period
  • After a few minutes, clean the screen using a soft cloth and wipe off all the toothpaste
  • Check whether the crack is still appearing on the screen. Mostly after this process, the crack becomes invisible. If the scratch persists, repeat the procedure carefully and attentively

Can Toothpaste Fix A Cracked Phone Screen?

When your phone slips out of your hand and lands face-down on a hard surface, the dreaded moment arrives – you discover that your once flawless screen now has an annoying crack. It’s a situation that many smartphone owners can relate to, and some even turn to unconventional methods in a desperate attempt to fix it. One such method that often circulates online is using toothpaste to repair a cracked phone screen. But does this unconventional solution actually work? Let’s find out!

  1. Toothpaste Ingredients: Before diving into whether toothpaste can fix a cracked phone screen, it’s essential to understand the composition of toothpaste. Toothpaste typically contains abrasives, such as silica or baking soda, to help remove stains and debris from teeth. It also contains gentle detergents, fluoride, and other ingredients to promote oral hygiene.
  2. Myth vs. Reality: Many viral videos and online tutorials claim that applying toothpaste to a cracked phone screen can magically fill in the cracks and make them disappear. However, it’s important to note that these claims are largely misconceptions. While toothpaste might have mild abrasive properties, it is not formulated or intended to fix electronic devices.
  3. The Abrasive Effect: Toothpaste’s mild abrasive nature may help remove some superficial scratches from the surface of a phone screen. However, when it comes to a genuine cracked screen, toothpaste doesn’t possess the ability to repair or restore it. Cracks on a screen typically occur in the underlying layers of glass or plastic, which toothpaste cannot fix or mend.
  4. Potential Risks: Attempting to fix a cracked screen with toothpaste may lead to undesirable outcomes. For instance, toothpaste could damage the oleophobic coating of your screen or create microscopic scratches that might hinder touch sensitivity or worsen the appearance of the device. Furthermore, there is a risk of introducing moisture into the phone’s delicate internal components, leading to potential damage.
  5. Professional Alternatives: If your phone screen is cracked, it is best to seek professional help and avoid home remedies like toothpaste. Consult a certified technician or visit an authorized service center to get a proper assessment and repair. They have the expertise and resources to replace the damaged screen or provide an effective solution tailored to your device.

So, while toothpaste may have some temporary effect on superficial scratches, it cannot fix a cracked phone screen. It’s crucial to rely on professional repair services to ensure the safety and longevity of your device. Remember, prevention is always better than attempting risky DIY solutions. Invest in a protective case and screen protector to minimize the risk of cracked screens in the first place.

Other Methods Of Fixing A Cracked Phone Screen

Toothpaste does not necessarily fix the cracks but rather hides them such that they become invisible. It is advisable to use very small toothpaste proportions to avoid blocking openings such as the earphone and charging plugs and other parts that may be vulnerable. Other methods to fix minor screens include;

Vegetable Oil

Just like the toothpaste, vegetable oil does not completely fix the scratch. This method is the least effective. You apply a dab of vegetable oil on the broken surface, and it disappears. This method is only applicable to minor scratches on the phone screen. However, this is not the best option since oil is very runny and can easily find its way into the phone’s crannies and nooks. When put in the pocket, the oil will disperse, leaving an even greater mess with the scratch still there.

Plastic Bag

You can use a plastic bag as an alternative to a screen protector if you cannot afford it. 

This method involves wrapping the plastic bag all-round the phone as it stops the screen problem from getting worse.


Using sandpaper on your phone screen requires great courage and care. It involves sanding down any small mark on the phone screen using sandpaper or a grinding machine. Make sure that you are careful to avoid scratching out the entire phone screen.

Baking Soda

 This process is almost similar to using toothpaste as you will need to make a paste from baking soda and water. Follow the same steps as using toothpaste to solve the problem.

Car Wax

Using car wax is another alternative to toothpaste. It is preferable as it leaves the phone with a sleek feel. Phone scratch repaired using car wax are long-lasting compared to ones repaired using toothpaste.

All these are just temporary solutions whereby in case they fail; you can visit a professional to fix and, in most cases, replace the screen. 

Can Toothpaste Damage My Phone Screen?

Toothpaste and baking soda are both abrasive compounds that can scrab out the outer layer of the screen. These substances make the phone look less scratched, and sometimes the scratches disappear completely. At first, the process may be harmless, but more serious screen-related problems may arise in the long run. Your phone may lose the ability to sense touch, or a non-attractive and blotchy screen is all that is left.

What To Do To A Scratched Phone?

Instead of using the home remedies that could lead to a more serious screen problem, you can consider using a screen protector. This process involves applying a plastic screen on top of the main screen to act as a protector. This alternative helps to hide the scratch as well as protecting the phone from more damages. Other than the plastic protector, there are also glass tampered protectors that are even better since a fresh glass layer is applied on the screen.

Unlike the plastic protector, the phone’s scratches can only be seen but cannot be felt when using the phone. Before using a screen protector, ensure that you clean the phone with less abrasive cleaners and products such as winex. Doing this will help to prevent further damage to the screen.

Another option that many people avoid is getting a replacement for the screen because the cost involved is very high. However, using an iFixit guide, you can replace the screen yourself, which is relatively cheap. You will need to have the necessary tools and the new screen to use as the replacement. Alternatively, if you are using iPhone, you can have the screens replaced by Apple at a premium with high-quality parts and a highly trained professional.

You may also decide to ignore the scratch if it does not alter the phone’s normal functioning. If the screen has a few blemishes, you can continue to use it the way it is.

What Are The Implications Of Using A Damaged Phone Screen?

  • A broken phone screen can cause health hazards since it can emit radioactive elements considered to be cancerous. 
  • When using a broken phone screen, one may cut their finger from the broken glass fragments. 
  • Broken screens cause strain to the eyes, especially the broken parts, which have a low-definition display
  • They also invalidate some unique phone features such as water resistance, making them prone to further damage. The phone’s inner parts are susceptible to damage, which could cause the total malfunction of the phone.

What To Consider When Using Toothpaste To Repair A Cracked Phone Screen

Toothpaste repairs phone cracks by cutting away a layer of scratch, making the scratch look less deep. Some kinds of toothpaste have harsh abrasive agents. Such kinds of toothpaste should be avoided because they strip off layers of the phone screen when applied. Your phone could lose a sense of touch to the phone screen. It would help if you considered using toothpaste with less abrasive agents that will be gentle on the phone screen to avoid additional scratches that may leave the phone with an unpleasant look.
