How to Get Started with Teeth Whitening at Home

So you want a brighter smile. You've seen the options, maybe you've tried a few things, and now you want to actually do it properly. Good news: getting started with teeth whitening at home is simpler than most people think you just need to know where to begin.

Here's everything you need to know.

First: choose the right formula

Before you pick a product, the most important decision is what's actually in it.

Peroxide-based whitening (hydrogen peroxide or carbamide peroxide) is the traditional approach. It can be effective but penetrates the enamel, which is why so many people experience sensitivity, gum irritation and discomfort.

PAP-based whitening is the modern alternative. PAP (Phthalimidoperoxycaproic acid) is a dentist-developed ingredient that targets stain molecules without penetrating the dentine. Clinically proven to whiten as effectively as peroxide with zero sensitivity.

At Polished London, every product is peroxide-free and PAP-based. That means results you can actually feel good about.

Choose your main whitening product

The best whitening product is the one you'll actually use consistently. Pick the format that fits your lifestyle:

• Teeth Whitening Strips — simple, mess-free and effective. Wear for 30 minutes and get on with your day. Great for beginners.
• LED Teeth Whitening Kit — for faster, more visible results. Our dual-light system accelerates the whitening process for a professional-level clean at home.
• Teeth Whitening Powder — use instead of toothpaste for an easy daily whitening habit. Comes in a plastic-free pot and packed with hyaluronic acid to hydrate as it brightens.

Add a daily maintenance routine

Consistency is everything with teeth whitening. Once you've chosen your main product, support it with a daily routine that keeps results building:

• Cloudberry + Mint Prebiotic Toothpaste — a daily prebiotic formula that gently brightens while supporting your oral microbiome.
• Hydroxyapatite Whitening Toothpaste — strengthens and remineralises enamel while whitening. Ideal if you have sensitivity concerns.
• Sonic XP Electric Toothbrush — a good toothbrush makes a bigger difference than most people realise. The Sonic XP delivers 40,000 brush strokes per minute, removing up to 10x more plaque than a manual brush and enhancing the results of any whitening routine.

How often should you whiten?

For best results, use your chosen whitening product daily especially in the first few weeks. Frequency is key. Stains build up gradually, so consistent daily use is what drives visible, lasting change.

Once you've reached your desired shade, you can switch to maintenance mode: a few times a week with your strips or powder, supported by a daily whitening toothpaste.

How quickly will you see results?

Everyone's starting point is different. Factors like your natural tooth colour, diet and how consistently you use the products all play a role.

As a guide:

• Strips: visible results from 7–14 days of daily use.
• LED Kit: visible results within the 14-day treatment plan.
• Powder: gradual brightening with daily use over 2–4 weeks.

We include a free shade guide with our kits and strips so you can track your progress properly.

Tips for the best results

• Brush your teeth before whitening, not after you want clean enamel for the whitening agent to work on.
• Avoid staining drinks (coffee, red wine, tea) for 30 minutes after whitening.
• Stay consistent — a few days on, a few days off won't get you the results daily use will.
• If you have veneers, crowns or implants, check with your dentist first whitening products work on natural teeth only.
