Orang Dadashian

Dr. Orang "Oscar" Dadashian DDS, MSc ImpDent, PG Cert RDP

One of our most experienced dentists, Oscar has been involved in placing and restoring dental implants since 2009. His formal training started at Eastman Dental Institute in Restorative Dentistry and continued with a two-year Diploma course in Implant Dentistry at Royal College of Surgeons. After a further year of study and research he then attained his Master of Science Degree in Dental Implantology. This journey has taken him all around the world to be trained by top professionals within this field. Oscar is actively involved in training and mentoring of other dentists in dental implantology.

As the principal dentist Oscar is a firm believer in the culture of patient and staff satisfaction. He continually ensures that all of the dentists that work with him work to a standard that he is proud of. By putting all patients first and ensuring that everyone is listened to and understood, cared for and given a first-class service, Oscar makes sure that each and every patient leaves the practice having received a level of care he himself would have wanted to receive.

With a soft and gentle approach Oscar has gained the admiration of thousands of patients from all over the UK, Ireland, Sweden & USA. With over 20 years of experience in dentistry, Oscar has learnt to put all of his patients at ease.

It is important to Oscar that Smile Dental Practice is a place where his staff can be proud to work. He believes that his staff spend more time at work than they do at home and this means that they need to be happy. By looking after the staff and dentists Oscar knows that his patients are receiving the best care.


He greets me in the waiting area every time I come to the practice. Having clear braces done with Oscar was the best thing I have ever done. I can now smile proudly
