Our Orthodontists

Dr Thomas Hartridge BDS, FDS, MSc, MOrth  (GDC reg number 71888)

Tom graduated from Bristol Dental Hospital in 1996 and obtained his orthodontic postgraduate qualifications from Bristol University and the Royal College of Surgeons in 2001. He is on the GDC specialist list for orthodontics.

Before qualifying as a specialist orthodontist Tom has worked as a general dentist and also worked for a number of years in hospital oral surgery posts. This provides the experience and knowledge to deal with the many problems seen in a specialist orthodontic practice.

Tom enjoys seeing the transformations possible from orthodontic treatment and the great improvements that can be made every day to peoples' lives.

Tom lives in Southsea with his wife and two young children, who keep him very busy when he's not working!


Dr Nicholas Turnbull BDS, FDS, MSc, MOrth, FDS (Orth) RCS Edin
(GDC reg number 67451)

Nick graduated from Cardiff Dental Hospital in 1992 and obtained his postgraduate qualifications from the Royal London Dental Hospital and the Royal College of Surgeons. He is on the GDC specialist list for orthodontics.

Following qualification as a specialist orthodontist he worked as a Consultant for the Royal Navy in Portsmouth. More recently, he continues to hold a part-time NHS Hospital Consultant post at Queen Alexandra Hospital, Portsmouth. He is closely involved in teaching and training new orthodontists and keeps up to date on the latest techniques by attending regular meetings and courses. He also lectures at clinical meetings regionally and nationally, and is a member of the British Orthodontic Society, the European Orthodontic Society, and the World federation of Orthodontists.

Nick has a clinical interest in adult orthodontics, high speed low friction treatment (Damon system) and low visibility cosmetic orthodontics.

Nick lives in Southsea with his wife and young daughter. His interests include running (he has completed a few marathons recently and the Great South Run most years) and snowboarding.

Dr Skjalg Johnsen DDS, PhD  (GDC reg number 84208)
Charles graduated from the Karolinska Institute Dental School in Stockholm, Sweden in 2000. While practicing as a general dentist he continued with research at the famous Karolinska Institute and obtained his PhD in 2005. Shortly after this he started a postgraduate training at the Eastman Institute in Stockholm and later obtained his orthodontic postgraduate qaulifications. He is on the GDC specialist list for orthodontics.
Following qualification as a specialist orthodontist he continued working at the famous Eastman Institute developing the department and leading the training of new specialists.
In the field of orthodontics he favours the Damon system, especially for adults, which allows shorter treatment periods and fewer visits based on low friction treatment. Further, when treatment planning Charles aims for ‘face-driven orthodontics’, meaning that focusing on the teeth is only a part of the whole picture. Modern specialists are trained to include the patients face, profile and lips in order to individualise and optimise the result.

Charles lives in Southsea with his wife. He has an interest in music and art, likes to travel and play badminton.
