Duncan J Park BDS (Hons) MFDS RCS (Eng) MMedSci (Dental Implantology)

Principal Dental Surgeon

GDC no. 82373

Excellence in any job comes from having a real desire and passion for the work, and this is something that Duncan has in abundance. This, combined with superb clinical standards, results in the best possible treatment for all his patients.

Duncan qualified from Sheffield University in 2003 with honours and the prize in restorative dentistry. His surgical skills were further developed by holding SHO and staff grade posts in hospitals including Sheffield, Barnsley and Chesterfield.

One of Duncan’s main interests is implant dentistry. Having completed implant training courses in Sheffield, he followed this up with the extensive post-graduate implant master’s degree at Sheffield University, so he is highly trained and experienced in implant treatment.

Updating knowledge is vital to keep on top of an evolving and ever-developing profession, so Duncan attends regular courses and conferences, as well as being a member of the Association of Dental Implantology (ADI).

Due to his expertise, Duncan accepts referrals from other dental practices for implant treatment, surgical work (e.g. difficult extractions and wisdom teeth), CT scans and IV sedation – types of treatment that would have traditionally been referred to a hospital. This in-house option can dramatically cut down on waiting times and the inconvenience of a hospital visit.

In his spare time Duncan enjoys road cycling and spending time with his family. He is an avid rugby supporter and played for many years for Sheffield before retiring in 2007 due to an injury
