How to use Teeth Whitening Strips

Before we get into the how, let's talk about why teeth whitening strips are one of the most popular ways to get a brighter smile at home. Simple, effective and easy to fit into any routine, here's everything you need to know.

Why use teeth whitening strips?

Whitening strips are a safe and cost-effective way to brighten your smile. They're easy to use, take just minutes a day, and results can be visible within a few days of first application. They work by removing surface stains caused by coffee, tea, red wine, smoking and other lifestyle factors.

With regular use, whitening strips help keep teeth looking brighter for longer. The flexible strip material conforms to your teeth for effective contact without slipping and with minimal daily effort, you'll start to see a noticeably whiter smile.

Benefits of teeth whitening strips

Whitening strips are one of the most accessible whitening options available:

• Safe and easy to use - peel, apply and leave.
• Remove surface stains from coffee, tea, red wine and smoking.
• Visible results in as little as three days.
• No trays, no mess, no expensive professional appointments.
• Peroxide-free - zero sensitivity.

Are Polished London strips vegan and peroxide-free?

Yes! Our multi-award-winning Advanced Teeth Whitening Strips deliver visibly whiter teeth with zero effect on enamel, thanks to our non-invasive PAP PRO formula developed with UK dentists for maximum results without peroxide.

Unlike traditional strips that use hydrogen peroxide (which can cause sensitivity, cavities and gum irritation), our PAP formula targets stain molecules directly without penetrating the dentine. Vegan-friendly, cruelty-free and PETA approved.

Use for 30 minutes a day to gently lift light stains, or up to 60 minutes to tackle deeper discolouration in fewer sessions.

How to use our teeth whitening strips

1. Tear open the foil packet to reveal two whitening strips one for the upper teeth and one for the lower.
2. Apply each strip to your teeth and leave for 30–60 minutes. Avoid eating or drinking during this time.
3. Remove the strips after your chosen time and discard them safely.

Tips for the best results

• Limit staining drinks (tea, coffee, red wine, cola) while on your whitening plan for best results.
• For deeper stains, use the strips for the full 60 minutes per session.
• We recommend using strips at night before bed this gives the whitening agents time to work without being washed away by food and drink.
• Brush before applying (not after) to ensure clean enamel for maximum contact.
• Take a photo in natural light on Day 1, then again on Day 7 and Day 14 to track your progress.

Once you've completed your whitening plan, keep your results going with a daily maintenance routine:
