Teeth whitening, done the medical-grade way.

How much does it cost?

Boutique Whitening starts at £385 for a straightforward case, rising to £600 for more complex cases, which can include internal bleaching where needed. Every course starts with a free consultation and 3D scan — a healthy tooth always whitens better, which is the reason for the exam, not a way of padding the bill.

Why we use Boutique, and nothing else

Boutique Whitening is manufactured in the UK under medical-grade regulation — dentist-prescribed, CE-marked, batch-controlled, and clinically tested. That matters because not all whitening is equal, even when the packaging looks similar. Dentist-supervised whitening uses stabilised, pH-balanced gel at a known concentration — 6% hydrogen peroxide for day whitening, or 10–16% carbamide peroxide for night whitening — fitted with custom trays and monitored throughout. Over-the-counter kits are legally capped at 0.1% peroxide, which is why they're mild, patchy, and short-lived by comparison, and beauty salons aren't legally permitted to use anything stronger either. Whitening is safe when a dentist does it. It isn't automatically safe done anywhere else.

Does it damage enamel?

No — and this is chemistry, not just reassurance. Enamel is made of millions of tightly packed mineral rods, held together by a softer sheath network, and this is where stain molecules (chromogens) accumulate over time from coffee, tea, red wine, smoking and simple ageing. Whitening toothpaste, working only at the surface, can't reach any of this. Peroxide gel enters the enamel and travels along these rod sheaths, reaching the chromogens trapped deep within, then continues into the dentine beneath in low, safe concentrations. Once it reaches a chromogen, it splits the large coloured molecule into smaller, colourless fragments that scatter light differently — which is why a tooth brightens from the inside, not the surface. None of this touches the enamel mineral itself.

Day or night whitening — which is right for me?

Day whitening involves wearing trays for 60–90 minutes at a time — fast and convenient, good for mild staining or a top-up before an event. Night whitening uses a gentler concentration worn overnight, better suited to sensitive teeth or deeper, older staining, and tends to give a more even lift over a slightly longer course.

What's the timeline?

The first few days bring a subtle shift as staining compounds start breaking down, and some sensitivity is normal and settles quickly. By around a week you'll usually see a clear one to three shade lift. Most patients reach their natural brightest shade somewhere between one and two weeks, with an optional boosting phase after that for deeper staining.

How long does it last?

Teeth look brightest in the first 24 to 48 hours, because the process temporarily dehydrates enamel — that's a normal rebound effect, not a sign the treatment is failing. Over the following one to two weeks, enamel rehydrates and the colour settles to its true shade, typically half a shade to one and a half shades down from that initial peak. From there, most patients hold a meaningfully brighter shade for twelve to twenty-four months, with only a slow drift over that time. Genuine relapse all the way back to the starting shade is uncommon.
