Queen's Gate Orthodontics

Orthodontic Excellence for You & Your Family


Queen’s Gate Orthodontics (QGO) is one of the longest established (1989), highest quality and award-winning dental practices in London. Lead by principal orthodontist, Claire Nightingale, who is an NHS Consultant with over 30 years experience in orthodontics, QGO is now part of the Portman- Dentex group, founded by Thomas’s parent, Sam Waley-Cohen.

Queen’s Gate Orthodontics awards include:

  • “Best Practice”, UK, 2020, in the Dentistry Awards;
  • “Highly Recommended, Practice of the Year” and “Highly Recommended, Best Referral Practice” in the Private Dentistry Awards, 2020,2021; 
  • “Best Principal” 2022 and “Best Team” 2023 in the Private Dentistry Awards.


As well as offering traditional fixed braces, Queen’s Gate Orthodontics is a leading provider of orthodontic treatment with Invisalign clear aligners for children and adults. 

Patient care is enhanced for all patients by using “Dental Monitoring” a self-scanning app, whereby patients can have their treatment progress and dental hygiene appraised frequently from the comfort of their own home, minimising unnecessary visits to the orthodontist. This is particularly convenient for families with busy lives and young people at boarding school. 

Our treatment opportunities are not just limited to braces. We have a wonderful general dentist and hygienist, so we can care for the whole family, and also offer anti-snoring devices for snorers, that delight their long-suffering partners.


We are proud to partner with Thomas’ Directory and offer:

  1. Orthodontic assessments for children under the age of 11 for £95 (reduced from £200 - £240).
  2. A complimentary gum shield (worth £165) using specialist scanning technology, which avoids nasty impressions / moulds, for every child of 11 and over who attends for an orthodontic consultation.

Directory Offer: Orthodontic assessments for unders 11s for £95 & FREE gum shields for over 11s who attend an orthodontic consultation.

My children and I have all seen Claire. They not only have (and will have) fantastic teeth but have enjoyed the whole straight forward process too. She, and her team, are all brilliant to deal with. And they are very good at calming nerves. The fact that she is in South Kensington is a massive plus too.

Having taken years to finally decide to fix my smile – Claire and her team came highly recommended and rightly so. They are professional, efficient and provide an excellent service. Claire is a perfectionist – she will not rest until your smile is perfect. What more could you ask of an orthodontist? Don’t hesitate.

Claire provided me with care that was second to none. I was always at ease and welcomed by Claire. She has a wonderful way of explaining everything, there were no hidden costs and I now have a smile that I love.

When our eldest daughter started sprouting crooked adult teeth, we lost no time in making an appointment with Claire and were not sure what to expect.  The surgery is friendly and welcoming from the moment you walk in the door, and any misgivings we had about ‘scary orthodontists’ quickly evaporated.  Our daughter took to Claire immediately, and actually managed to share a joke and a smile whilst being fitted for a brace.  Claire has a very practical approach, which is especially welcome where children are involved.  She avoids taking unnecessary action, preferring with children to see how growing teeth space and position themselves before deciding on whether a brace is the right way to go.  I have two younger daughters and will have no hesitation in taking them straight to Claire when the time comes.  Our eldest’s beautiful smile is a daily and welcome reminder of a job done well.
