You want a smile you're not embarrassed to show in photos, but London's cosmetic dentistry scene is crowded with practices making big promises. The cosmetic dentists in London on this page have logged more than 2,500 Google reviews between them, and every single one holds a rating between 4.8 and a perfect 5, a tight band that says the bigger question isn't who's good but who's right for veneers, bonding, or a simple whitening session.
Short answer: Marylebone Smile Clinic, a Featured Partner on this page, holds a perfect 5.0 rating across 212 reviews. Dental Smiles London has by far the deepest review base at 884 reviews and a 4.8 score, while Brighten Up Teeth Whitening advertises single-visit laser whitening from around £199. Composite bonding elsewhere on this list runs roughly £150 per tooth, but get a written quote for anything beyond whitening.

Dental Smiles London | Euston Practice
4.8★★★★★884 Google reviews
Dental Smiles London runs a general and cosmetic dental practice on Chalton Street in Euston, part of a small group with sites in Kings Cross too. Alongside routine dentistry the practice offers Invisalign, fixed braces, veneers, crowns, implants and teeth whitening, and it explicitly caters to nervous and anxious patients. With 884 reviews it has by far the largest review base of any practice on this list.
What people praise
- Reviewers repeatedly mention the team's patience with dental anxiety, describing being put at ease from the first visit
- Patients undergoing Invisalign treatment report being happy with results and clear communication throughout
- The practice is easy to reach by public transport, which several reviewers call out as a genuine plus
Worth knowing
- With 884 reviews, the rating naturally includes more of the occasional lower-star review than the smaller practices on this list, though the overall pattern stays strongly positive
- As a general dental practice with cosmetic services layered on, it's a slightly different fit than a pure cosmetic specialist

Brighten Up Teeth Whitening
4.9★★★★★522 Google reviews
Brighten Up is a teeth whitening specialist near Trafalgar Square, focused entirely on laser whitening rather than broader cosmetic dentistry. Treatments are carried out by GDC-registered dental professionals, and the clinic advertises single-visit results and a take-home kit to maintain them.
What people praise
- Reviewers consistently describe a real, visible improvement in tooth shade within a single 90-minute visit
- The calming setting is mentioned repeatedly, alongside friendly technicians who explain the process clearly
- Several reviewers who tried a discounted first visit say they came back and paid full price because they rated the result that highly
Worth knowing

How we score these clinics
We compared live Google ratings and review counts for cosmetic dentists across London, then ranked the field on the star rating, how many reviews back it up, how recently people are still reviewing, and how complete each listing is. No business can pay to change these numbers. Marylebone Smile Clinic’s placement is a paid Featured Partner slot; its underlying rating and review count are the same real Google data as every other practice here.
What does cosmetic dentistry cost in London? (2026)
Cosmetic dentistry pricing varies hugely by procedure, and most practices on this list don’t publish a fixed rate card online. Two data points are worth knowing: Brighten Up’s laser whitening is advertised at around £199 for a single visit as a promotional rate, and patients at Harley Street Dental Art Clinic have reported paying roughly £150 per tooth for composite bonding as part of a multi-tooth smile package. Veneers, Invisalign and implants cost considerably more and depend on how many teeth are involved, so always ask for a written, itemised quote before committing.
| Job | Typical price |
|---|
| Laser teeth whitening (single visit, promotional rate) | ~£199 |
| Composite bonding (per tooth, multi-tooth package rate) | ~£150 |
Prices as advertised on Brighten Up Teeth Whitening’s own site and as reported by patients reviewing Harley Street Dental Art Clinic, checked July 2026. Individual quotes will vary by case.
Serving all of London
These six practices cluster around Harley Street, Euston, Covent Garden and Belsize Park, with Trafalgar Square covered too. From Fitzrovia to Bloomsbury to the West End, one of these six is a short trip on foot or by tube.
What to ask before booking cosmetic dental work
- Can I see before-and-after photos of your own patients, not stock images?
- What’s included in the quoted price: consultation, X-rays, follow-up visits?
- How many years has the treating dentist been doing this specific procedure?
- What happens if I’m not happy with the result, and is there a guarantee?
- How long is the treatment expected to last before touch-ups are needed?
- Is financing or a payment plan available for larger cases like veneers or implants?
Frequently asked questions
Are these rankings paid?
No. Rankings come from public Google data. A business can pay to be a Featured Partner (badge and top placement), but that never changes another business’s score or position. Marylebone Smile Clinic is a Featured Partner on this page; the other five are ranked purely on their own numbers.
How did you choose these six practices?
We compared cosmetic dentists across London on Google, then ranked the ones with a genuine, ongoing review history on rating, volume, recency and listing completeness.
What’s the difference between veneers, bonding and whitening?
Whitening lightens your natural teeth, bonding reshapes or repairs a tooth with a tooth-coloured resin, and veneers are thin custom shells bonded over the front of the tooth for a more dramatic, longer-lasting change. Several practices here specialise in one or the other.
How often is this page updated?
We refreshed the data behind this page in July 2026 and recheck it periodically as new reviews come in.
Does a Featured badge mean a business scores higher?
No. Featured is a paid placement badge, not a quality signal we control. Marylebone Smile Clinic’s real rating and review count would put it near the top of this list on merit alone.
The bottom line
For a full smile makeover, Marylebone Smile Clinic and The London Centre for Cosmetic Dentistry both bring decades of specialist experience and near-perfect scores. If you just want whiter teeth without the bigger commitment, start with Brighten Up instead. Whichever you choose, get a written quote before any work begins.
