Everything You Need to Know About Teeth Whitening Gel

Your smile is one of the first things people notice, and it deserves the very best care. When it comes to whitening your teeth, not all gels are created equal.

The truth is, most whitening gels rely on hydrogen peroxide or carbamide peroxide. While peroxide can remove stains, it also causes sensitivity, gum irritation, and long-term enamel erosion. That’s why so many people quit halfway through their whitening journey the pain simply outweighs the results.

At Polished London, we’ve changed the game. 

Our Whitening Gel is proudly UK made and powered by an 18% concentration of PAP Pro Whitening technology (Phthalimidoperoxycaproic acid), a next-generation teeth whitening ingredient clinically proven to brighten teeth safely at home. It’s peroxide-free, dentist-created, clinically tested, and designed for everyday smiles. This is whitening, upgrade

What Exactly Is Whitening Gel?

Whitening gel is a targeted treatment that removes everyday stains from the enamel. From coffee and tea to red wine and food pigments, stains build up gradually and dull your natural shade.

Applied directly to the teeth, whitening gel penetrates the surface layer of enamel, breaking down stains and restoring brightness. The results depend on the formula.

• Peroxide gels: harsh, aggressive, risk sensitivity.

• PAP gels: gentle, effective, enamel-safe

Why PAP Is the Future of Whitening

PAP (Phthalimidoperoxycaproic acid) is the modern alternative to peroxide — and it’s transforming whitening worldwide.

 Enamel-Safe – Unlike peroxide, PAP does not release free radicals that attack enamel.

 No Sensitivity – PAP whitens without pain or irritation.

 Clinically Proven – Backed by studies to be both safe and effective.

 Consistent Results – A gradual, even brightness that lasts.

With PAP, you can finally whiten with confidence without the sensitivity.

 Fact: With peroxide, yes. With PAP, no. PAP actively protects enamel while lifting stains.

 Myth: At-home whitening doesn’t work.

 Fact: Clinically proven PAP formulas deliver visible results at home, safely.

Myth: The stronger the formula, the better.

 Fact: Stronger peroxide = stronger damage. Smart whitening is about balance, not brute force.
