The Treatment
What Is Professional Whitening?
Professional teeth whitening at Denstudio uses prescription-strength 16% carbamide peroxide gel — 32 times stronger than anything available over the counter. This clinical-grade formula penetrates deep into the enamel to break down stubborn stains caused by coffee, tea, red wine and everyday wear.
Your custom SuperFit trays are precision-crafted from 3D digital scans of your teeth using our proprietary SuperFit technology. Unlike generic one-size-fits-all trays, SuperFit trays hug every contour of your teeth for perfectly even gel distribution and maximum whitening power.
Our FreshGel formula is designed to minimise sensitivity while delivering powerful, long-lasting results. Simply wear your trays for a few hours each night over 7 to 14 days and watch your smile transform. You will start to see visible results within the first few sessions.

Common Questions
Frequently Asked Questions
You will start to see visible results within the first few sessions. Most patients achieve their desired shade within 7 to 14 days of nightly wear. The exact timeline depends on your starting shade and your whitening goals.
Yes. Our professional whitening system uses dentist-prescribed 16% carbamide peroxide gel in custom-fitted trays. Because the trays are made from precise 3D scans of your teeth, the gel contacts only your enamel and not your gums, minimising the risk of sensitivity or irritation.
Our FreshGel formula is specifically designed to minimise sensitivity. The custom SuperFit trays ensure the gel sits precisely against your teeth without leaking onto soft tissue. Most patients experience little to no sensitivity throughout their treatment.
With proper care, results from our professional whitening system last up to 3 years. Because you keep your custom trays, you can top up your whitening at home whenever your smile needs a refresh — simply order more gel from us.
Our prescription gel is 32 times stronger than anything available over the counter. Combined with custom 3D-scanned trays that ensure even coverage, our system delivers dramatically whiter, more consistent results. Shop-bought kits use generic trays and low-concentration gels that produce patchy, short-lived results.
Whitening gel does not change the colour of porcelain veneers or composite bonding. If you are planning restorative work, we recommend whitening first so your dentist can match the new restorations to your brighter shade. If you already have restorations, we can advise on the best approach during your consultation.
We stand behind our whitening results. If you follow the treatment plan as prescribed and do not achieve noticeably whiter teeth, we will refund your treatment cost in full. We discuss expectations during your consultation so there are no surprises.
Absolutely. Whitening pairs beautifully with Invisalign, composite bonding and porcelain veneers. Many of our patients include whitening as part of a complete smile makeover package. Our add-on whitening is available for just £295 when combined with another treatment.
