You spotted a scratch on your phone screen and immediately started searching for a fix. The internet is full of suggestions — toothpaste, baking soda, car polish, even banana peels. Most of them will make things worse. Here is what actually happens when you try to remove a phone screen scratch, what the real options are, and when replacement is the only honest answer.
The Short Answer
Whether you can remove a scratch depends entirely on where it is:
- Scratch on a screen protector — Yes, easily. Replace the protector ($10–20) and the glass underneath is untouched.
- Scratch in the oleophobic coating — Partially. The coating wears off over time anyway; a screen protector hides it. You cannot restore the original coating at home.
- Scratch in the actual glass — No practical DIY fix exists. The glass has been physically removed. Only professional resurfacing (rare, limited) or a screen replacement addresses it.
Before trying anything, use our Screen Scratch Test to inspect the damage carefully under full-screen shades with the light sweep enabled. This helps you determine how deep and widespread the scratch is.
Why the Toothpaste Scratch Myth Doesn't Work
The toothpaste scratch myth comes from the fact that toothpaste can polish soft surfaces like CDs, acrylic, and chrome. Phone glass is a different material entirely. Modern smartphone glass — Gorilla Glass, Ceramic Shield, Dragontrail — is engineered to score 6–7 on the Mohs hardness scale. Toothpaste abrasives score around 3–4. They cannot touch the glass.
What toothpaste can damage is the oleophobic coating — the thin fluoropolymer layer on top of the glass that repels fingerprints. Once that is gone, the glass becomes significantly greasier and harder to clean. Baking soda, metal polish, and car wax carry the same risk and the same result: coating removed, scratch unchanged.
What the Oleophobic Coating Actually Is
The oleophobic coating is not glass — it is a few nanometers of fluoropolymer applied on top. It wears away naturally over one to two years of normal use, which is why older phones feel greasier. A scratch in this layer looks like a dull line that disappears when the screen is wet, rather than a sharp groove you can feel with a fingernail.
You cannot restore this layer at home. Third-party oleophobic sprays exist but provide a fraction of the original protection and last only a few weeks. The realistic fix is to apply a tempered-glass screen protector, which comes with its own fresh coating on top.
Professional Screen Scratch Repair Options
A handful of professional repair services offer glass resurfacing — using fine polishing compounds and rotation equipment to remove a thin layer of glass and feather the scratch. Results vary:
- Works best on very shallow scratches that do not penetrate deeply into the glass.
- Removes a small amount of glass, thinning the panel slightly and reducing its impact resistance.
- Costs $30–80 and is not available at most repair shops — it requires specialized equipment.
- Does not address cracks that have fractured the glass (as opposed to a surface gouge).
For most scratches on modern phones, this is rarely worth it. A tempered-glass protector that hides the scratch costs $10 and adds protection for future drops.
When Screen Replacement Is the Right Call
Screen replacement makes sense when:
- The scratch is deep enough to feel with a fingernail and runs across a frequently-used part of the display.
- There are stress fractures or micro-cracks branching from the scratch — these can spread and risk glass shards with a future drop.
- Touch sensitivity is affected in or near the scratched area (indicating damage to the digitizer layer beneath the glass).
- The phone still has significant resale or use value that justifies the repair cost.
For context, a reputable third-party repair shop typically charges $80–200 for screen glass replacement on mid-range phones and $200–350 for flagships. Manufacturer replacements are higher but use original parts.
How to Hide a Scratch Without Replacing the Screen
If the scratch is cosmetic and not worth paying to repair, a tempered-glass screen protector is your best option. A quality protector sits on top of the damaged surface, adds its own oleophobic coating, and means that any future scratches hit the protector — not the glass. At $10–25, it is the cheapest form of screen scratch repair available.
When applying a new protector over an existing scratch, clean the screen thoroughly first. The scratch will still be visible if you look carefully at an angle, but at typical viewing distances it becomes unnoticeable.
How to Prevent Scratches in the First Place
| Habit | Scratch Risk |
|---|---|
| Phone loose in pocket with keys | High — keys score 5.5 on Mohs, enough for most glass |
| Phone in bag with loose change or sand | High — sand is quartz (Mohs 7), harder than glass |
| No screen protector | Moderate — glass survives most surfaces but not keys or sand |
| Tempered-glass protector applied | Low — protector takes the damage |
| Phone face-down on rough surface | Low-moderate — depends on surface hardness |

Frequently Asked Questions
Does toothpaste really remove scratches from a phone screen?
No — the toothpaste scratch myth is persistent but wrong. Toothpaste contains mild abrasives that can polish soft materials, but phone glass (Corning Gorilla Glass, Ceramic Shield) is far harder than toothpaste can affect. What it does do is strip the oleophobic coating that keeps fingerprints off, leaving your screen greasier and harder to clean. Avoid it entirely.
Can baking soda or toothpaste buff out a phone scratch?
No. Both are too soft to touch hardened glass and will only damage the oleophobic coating on top. A scratch that goes into the glass requires mechanical removal of glass — something only professional resurfacing equipment can do, and even then it risks thinning the glass and weakening it.
How can I tell if the scratch is on my screen protector or the actual glass?
Tilt the phone in bright light and look at the depth of the line. A scratch on a screen protector sits on the very top surface and often has a slightly lifted or uneven edge nearby. If you can feel a distinct groove when running a fingernail very gently across it, the scratch likely reaches the glass. When in doubt, try removing the protector — if the scratch disappears, it was only the protector.
How much does phone screen scratch repair cost?
Professional screen resurfacing (polishing) typically costs $30–80 and is only practical for very light coating scratches, not glass scratches. A full screen replacement for a modern flagship phone ranges from $150 to $350 at a repair shop, or up to $500 via the manufacturer. For budget phones, replacement often costs more than the phone is worth used.
Will a scratch get worse over time?
A hairline scratch in the glass itself is unlikely to spread under normal use. However, a crack — even a tiny one — can spread with temperature changes, pressure, or a subsequent drop. If you see a line that branches or has visible fracture patterns at the ends, protect it immediately with a tempered-glass screen protector and avoid pressure near that area.
What is the best way to prevent phone screen scratches?
Apply a tempered-glass screen protector as soon as you get the phone. Tempered glass is harder than plastic protectors and takes real-world scratches so your display does not have to. Keep your phone in a separate pocket from keys and coins. Use a case with raised lips around the screen edge so the glass does not contact flat surfaces face-down.
