A message from Nicolai

My name is Nicolai Orsteen and I am a registered specialist in endodontics in both the UK and my home country of Norway. I have worked as a specialist for more than 10 years, and my practice is solely limited to root canal treatments. In my opinion, you need to practice tirelessly to be an expert in your field, and I have successfully completed more than 10,000 root canal treatments.

Amongst other places, I have worked in a specialist endodontic practice in Harley Street. I eventually set up the Root Canal Dental Referral Centre to offer patients in and around Richmond high quality specialist root canal treatment for a reasonable fee.

Consultant and Clinical Lecturer, Peninsula Dental School
Specialist in Endodontics
GDC Number: 177319

Ammar was born and raised in Scotland. He studied both at Glasgow Dental School and at Liverpool Dental School.

Ammar achieved his Bachelor of Dental Surgery from Glasgow Dental School in 2009. After spending several years as a Senior House Officer (Glasgow & Dundee Dental Hospital), as well as a General Dental Practitioner in Scotland, Ammar realised that Endodontics was the field of dentistry that he really enjoyed the most. He embarked on a three-year full-time Endodontic Specialist training programme at Liverpool Dental School.

His doctorate project investigated the effect of orthodontic treatment on traumatised teeth and its implications on the dental pulp.

Ammar’s passion for teaching and academia led him to create The EndoGuys, which provides endodontic teaching to general dental practitioners across the UK.

Ammar offers all aspects of endodontic therapy, be it non-surgical or surgical endodontics, as well as trauma management and paediatric endodontics, in a relaxing, patient-friendly and pain-free approach.
