We are a long established family practice with origins dating back to Portland Place over seventy years ago. The practice moved to Cavendish Square, being acquired by Barry Bloom in 1973 and was run according to his philosophy of conservative care using state of the art techniques. In 2007 Raj Gonsai joined the practice at the invitation of Mr Bloom to provide a more advanced approach toward modern treatment planning. In 2010 Raj succeeded Barry as Principal dentist at the practice and continues to work alongside Barry taking the practice forward.

Today the practice consists of a team of five leading dental practitioners, two well experienced hygienists and assisted by a set of support staff second to none. We are proud to offer a comprehensive set of treatments ranging from routine family care to full mouth rehabilitation using same day implant treatments.

With a commitment to excellence in everything that we do, from fast and effective emergency dental care to a meticulous approach to routine and complex treatments

We continue to place great emphasis on carrying out the very best in evidence based dentistry in a happy caring environment. With facilities seldom matched in the heart of the Harley Street medical district, we are proud that many existing patients remain with us from when the practice was first established and are now choosing to continue their care at our new site in Weymouth Street.

Dr Raj Gonsai

Principal Dentist

BDS (London 1997),  MSc ConDent (EDH 2007)

Described by both peers and patients alike as a ‘highly committed and skilled practitioner’, Raj’s special interests lie in all aspects of routine and advanced restorative dentistry, cosmetics and full mouth rehabilitations. Raj has a meticulous and precise approach to his work focussing upon trusted, evidence-based, modern approaches to care that has led to a reputation of only offering the very best in quality of treatment and standards of care for his patient base in the heart of the Harley Street medical district.

Raj graduated from St. Bartholomew’s & The Royal London Hospital School of Medicine and Dentistry having been awarded numerous clinical distinctions during the continually assessed undergraduate course. With over 19 years of experience in successful clinical practice, his postgraduate awards include Certificates in Surgical and Prosthodontic Implantology, Removable Partial Dentures and Applied Clinical Materials, leading to him being awarded a Postgraduate Diploma in Restorative Dental Practice by the UCL Eastman Dental Institute. Feeding a further desire to provide the very best of care for his patients, he then followed this by undertaking a Masters Degree in Conservative Dentistry from the prestigious Eastman Dental Hospital (UCL) allowing a focus on his main interest in the field of Prosthodontics, the branch of dentistry concerned with restoring or replacing damaged or missing teeth.

His ongoing achievements and focus on quality based, high standards of patient care led to Raj being invited to join our dental practice in 2007. Quickly establishing himself within a patient base that has been present with the practice for over seventy years, a natural progression saw him taking over the ownership from Barry Bloom in 2010. Raj practises here four days a week and continues with his strong commitment to postgraduate education by attending a wide range of courses and conferences both at home and abroad. He is a member of The British Society for Restorative Dentistry, The British Dental Association and the International Team for Implantology (ITI).
