Teeth Whitening

Combination whitening pairs a dentist-applied in-practice treatment with custom take-home trays for the brightest, longest-lasting result.

Combination whitening pairs an in-chair laser whitening session with custom take-home whitening trays. The laser session (around 90 minutes) kickstarts the process with dramatic, immediate results. Home whitening (2–4 weeks of nightly use) then extends the effect, reaches any remaining surface staining, and stabilises the final shade. Together, they deliver a whitening outcome several shades beyond what either treatment alone can achieve — and the results last significantly longer.

Maximum brightness. The brightest whitening result we offer. Laser tackles deep and surface staining; home trays refine and extend the effect. Dramatic, lasting transformation.

Immediate impact, lasting results. See visible change on day one (laser session), with your final result over the following 2–4 weeks. Longer-lasting than either treatment on its own.

Built-in maintenance. You keep your home whitening trays forever. Occasional top-up sessions (a few nights every 6–12 months) maintain your brightness indefinitely — and cost a fraction of the initial treatment.

Combination whitening isn’t just two treatments stuck together — it’s a carefully-planned sequence. At Clarendons, we time the laser session, the start of home whitening, and the rest periods between them to get the best possible result without overloading your teeth. The gels are professional strength. The trays fit precisely. And everything is tailored to your teeth, your starting shade and your sensitivity.

Our award-winning clinic in Leeds city centre gives combination whitening the care it deserves. Proper consultations. Calming in-chair sessions. Thoughtful aftercare. Flexible finance to make it affordable. And long-term support — because we want your new smile to last as long as possible.

Our take-home whitening uses custom-made trays and dentist-prescribed gel so you can safely whiten at your own pace at home.

Home whitening uses custom-fitted plastic trays — made from 3D digital scans of your teeth — to hold professional-strength whitening gel against your enamel. The gel (typically 16% carbamide peroxide or 6% hydrogen peroxide) breaks down stains from within the tooth, delivering a genuinely whiter smile over 2–4 weeks of nightly use. Results are visible within days, and the full course reveals a shade change of several levels on a dental whitening chart.

Custom-fit trays. Made from precise digital scans, our trays hug your teeth perfectly — delivering even whitening without gel leakage or gum irritation.

Prescription-strength gel. Up to 32x stronger than high-street kits. Fast, visible results in days. Backed by proven science and dentist supervision.

Do it on your own time. Wear your trays overnight while you sleep, or for a couple of hours during the evening. No time off work. No disruption to your routine.

There’s a world of difference between dentist-led home whitening and the DIY strips or beauty-salon gimmicks you’ll find online. We start with a full oral health check to ensure whitening is safe for you (no point whitening teeth with undiagnosed decay). We take digital scans for perfectly-fitting trays. We prescribe gel strength based on your sensitivity and goals. And we’re available throughout the process for support and advice.

Our award-winning clinic in Leeds city centre makes the whole process simple. Two short appointments: consultation and tray fitting. Then home whitening at your own pace. Your shade is tracked so we can show you the results, and maintenance top-up gels are available for years to come. Just properly-done whitening, without the hype.

Icon resin infiltration removes white spots and early decay marks from teeth in one visit, with no drilling and no injections.

Icon is a specialist resin infiltration system designed to treat white spot lesions — those chalky, opaque patches on teeth caused by demineralisation. Common causes include post-orthodontic demineralisation (after braces), dental fluorosis (excess fluoride during tooth development), and very early-stage decay.

Icon works by first etching the tooth surface with a mild acid to open the pores, drying the area thoroughly, then infiltrating a low-viscosity resin into the porous lesion. The resin sets with a curing light, filling the porous enamel and restoring a natural, even appearance. No drilling. No enamel removal. No injections.

No drilling, no injection. A truly micro-invasive treatment. No anaesthetic needed, no enamel removed. The perfect answer for white spots in patients who’d prefer not to veneer or bond over healthy teeth.

Single-appointment solution. Most Icon treatments are completed in 45–60 minutes. Visible improvement in one visit — sometimes dramatic transformation, depending on the depth of the lesions.

Preserves your natural tooth. Unlike veneers or crowns, Icon treats the lesion inside the tooth without altering the external structure. Your natural tooth is conserved entirely.

Icon isn’t a magic cure-all — it works beautifully on the right kinds of white spots and less so on others. At Clarendons, we assess your specific lesions carefully: their cause, depth and location. For superficial demineralisation after braces, Icon often delivers transformative results. For deeper fluorosis or thick white patches, it may not be the right answer — and we’ll tell you honestly, rather than selling treatment that won’t deliver.

Our award-winning clinic in Leeds city centre is trained in the Icon technique and delivers it with care. Calming environment, no injections needed, and transparent pricing. If Icon is right for you, it’s one of the most satisfying treatments in cosmetic dentistry — a completely reversible, minimally-invasive solution to a cosmetic problem that’s bothered you for years.

Internal bleaching whitens a tooth that has darkened after root canal treatment, restoring it to match your natural smile without a crown.

Internal (or non-vital) bleaching is a technique used to whiten a single tooth that has darkened from the inside — usually after root canal treatment, internal bleeding from trauma, or long-standing stains trapped within the tooth. A small access hole is made in the back of the tooth (often reopening the root canal access), the canal is sealed, and a bleaching agent is placed inside the pulp chamber.

The tooth is then sealed with a temporary filling. Over the following days or weeks, the bleach lightens the tooth from within — a technique sometimes called the “walking bleach”. Once the desired shade is reached, the bleach is removed and a permanent filling placed.

Targets single darkened teeth. External whitening doesn’t reach internal staining. Internal bleaching goes directly to the source — brightening one tooth to match its neighbours.

Less invasive than veneers. Before resorting to a veneer or crown, internal bleaching can often restore colour without any significant tooth preparation. Preserves natural tooth structure.

Surprisingly effective. Most internally-stained teeth respond brilliantly — often back to matching shade within 1–3 sessions. Gentle, incremental, controlled.

Too many patients with a single dark tooth are straight-up sold a veneer — an irreversible treatment that requires enamel removal. At Clarendons, we always assess whether internal bleaching might solve the problem first. It’s cheaper, less invasive, and often gets you a result you’re delighted with. Only if bleaching isn’t the right solution do we discuss veneers or crowns.

Our award-winning clinic in Leeds city centre handles internal bleaching with the expertise it deserves. Proper assessment of the tooth’s root canal status, precise technique, close monitoring, and follow-up restorations that protect the treated tooth long-term. Delivered in a calm, spa-like environment with clear pricing and flexible payment options.

Laser (light-activated) teeth whitening lightens your teeth several shades in a single dentist-supervised appointment, ideal before an event.

Laser (or light-activated) whitening is an in-chair procedure where high-strength whitening gel is applied to your teeth and activated with a specialist light or laser. The light accelerates the whitening reaction, breaking down deep stains far faster than gel alone.

Your gums are protected with a liquid dam throughout. Sessions typically last 60–90 minutes and deliver visible results before you leave the clinic. It’s the fastest way to whiten teeth professionally.

Dramatic results, single visit. No weeks of waiting. Laser whitening delivers 6–8 shades brighter in a single 90-minute appointment. Ideal for weddings, events or when you just want results now.

Safe, protected, expert-led. Gums are protected with a liquid dam, enamel is preserved, and every minute of treatment is monitored by your dentist. Safer than beauty-salon whitening. Faster than DIY.

Pair with home whitening. For maximum impact, many patients combine laser with home whitening. The kickstart-plus-top-up approach delivers the brightest, longest-lasting results.

Laser whitening has a reputation for causing sensitivity — usually because it’s been rushed or overdone. At Clarendons, we calibrate every session carefully: strength of gel, number of cycles, break time between cycles, tailored to your teeth and sensitivity level. The result is dramatic whitening without the next-day agony.

Our award-winning clinic in Leeds city centre makes your laser whitening session feel almost spa-like. Comfortable chair, calming environment, attentive team. And afterwards, we provide clear aftercare guidance to help your new shade last as long as possible. Fast doesn’t have to mean rough — not here.

Lost or worn whitening trays? We make replacement custom-fit whitening trays from a quick digital scan — no messy impressions — so you can keep topping up your smile. Ask about our dual-purpose appliances that work as both a retainer and a whitening tray, keeping your teeth straight and bright at once.

Ask us about pricing at your consultation — we’ll tailor it to you.

When your whitening gel runs low, book a quick consultation so we can check it's safe to top up before ordering more. We offer two gel types — a daytime gel and an overnight gel — available in 2 or 4 syringes.

If you grind your teeth, you need the daytime gel. A whitening tray flexes as you grind, which lets the gel spill out and saliva wash in, diluting the concentration so it won't work properly.

Our whitening is led by Dr Ahmed Al-Ani, whose MSc in Restorative & Aesthetic Dentistry (University of Manchester, Merit) focused on teeth whitening — so you get the tray designs and gels that genuinely work, not gimmicks, without wasting money.
