Qualifications

Qualifications

  • Graduated in France (Strasbourg) in dental surgery in 2009
  • Degree in dental surgery, Strasbourg
  • Incognito Certification Course, Birmingham
  • Invisalign®, clear aligner, London
  • Lingual Braces, System WIN, London
  • Centre for Teaching Orthodontic Techniques, CETO, Paris

 

Marie graduated from the Faculty of Dentistry in Strasbourg and qualified at the CETO (Centre for Teaching Orthodontic Techniques) in Paris. In June 2011, Marie moved to live and work in London. In November 2017, she founded The Dental Chambers with her colleague Dr Friedmann.

Her interest in orthodontics allows her to treat children and adults. Her skills range from conventional brackets to lingual braces (placed at the back of the teeth for maximum discretion) by 3M(™) Incognito (™) as well as transparent aligners from Invisalign®.

Marie has a special interest and thorough experience in interceptive treatment for young children where particular attention is paid to the asymmetry of jaw growth. They are treated with a removable or fixed appliance to guide growth and allow permanent teeth to erupt more easily. This in turn reduces the time of orthodontic treatment in adolescence and improves their overall wellbeing.

Marie has a passion for travelling, especially to places where she can take to the mountain slopes with her skis. She also loves watersports, especially kite surfing.

Dr Ros Selfe
Dental Hygienist

Qualifications

  • University of Sheffield. Bachelor of Dental Surgery (Hons), 2010
  • University College London. Master of Philosophy in Chemistry, 2004
  • University College London. Master of Science, Medicinal Chemistry, 2003

Languages spoken: English and French

Ros studied Dentistry at Sheffield University, bringing a wealth of knowledge and expertise to her role as a dental hygienist. 

She is dedicated to helping patients maintain healthy gums and teeth through expert dental hygiene care, and is passionate about educating patients on the importance of gum health and preventing gum disease. With her gentle and caring approach, Ros ensures that every patient feels comfortable and at ease during their visit.

Ros offers a range of treatments, including scaling (the removal of harmful plaque and tartar from around the gumline) and personalised advice on maintaining optimal oral hygiene. She also offers air flow, a technique for polishing teeth that involves a targeted jet of compressed air, water and a polishing powder. It allows the gentle yet effective removal of stains and plaque from the surface of teeth.

Ros recommends visiting a dental hygienist at least every six months to enable regular cleanings, and for the early detection and treatment of gum disease. More frequent visits may be needed for those with existing gum concerns or orthodontic appliances. 

Children should begin seeing a hygienist early on to establish healthy habits and protect their growing teeth. For orthodontic patients, regular hygiene visits are especially important to prevent plaque and tartar build up around braces or aligners, ensuring both gum health and the success of the orthodontic treatment. Ros works closely with orthodontic patients to help them maintain a clean and healthy mouth throughout their treatment. 

Patients can book directly to see Ros, and she offers evening appointments to accommodate busy schedules.

Outside of the clinic Ros enjoys reading, and playing the drums and guitar.

Follow up calls to make sure I was doing well

I am very grateful to Dr Friedmann. He did a very tricky wisdom tooth extraction, took the time to think about how to do it the best way and followed up with two phone calls afterwards to make sure that I was doing well.
