Oral Surgery | Dr Leigh Ann Morgan

Dr Leigh Ann Morgan

Dr Leigh Ann Morgan

As soon as you meet me, you will probably figure out from my accent that I am originally from South Africa. Isn’t there a saying going around, that at some point whilst living in the UK, you will either visit a South African dentist, be a South African dentist, or know a SA dentist!I qualified as a dentist just after turning 21 years old. My aim was to travel and see the world. Like many of my class mates, I headed to the UK, probably because English is my first language, the UK at the time was crying-out for dentists, and they recognised our university degree, also the UK was a great base from which to explore Europe and the world.

My first practice was in Scotland, Aberdeen which I enjoyed, I then proceeded to further my training at the Aberdeen Royal Infirmary in their Maxillo-Facial and Oral Surgery unit. I returned to general dental practice eventually moving down to Oxford and now London.

I believe that having a balance between private practice, academia and research and teaching, allows me to have a continuous wonderment of the dental profession. Although my training is primarily in oral surgery, I have always maintained a solid footing in general dental practice.

I love the variety that general dentistry allows, fillings, root canals, crowns and inlays, oral surgery, orthodontics and cosmetic and minimal invasive dentistry are all in a days work. Difficult surgical extractions, implant surgery, IV sedation all these skills make me better at routine dentistry, and routine dentistry makes me better at surgery.

Professor Alison Loescher is Lead Orofacial Pain at the Charles Clifford Dental School Sheffield

In 2003 Tilly initiated a service to manage patients with chronic orofacial pain. The service is now well established and receives referrals from a wide geographic area, including many tertiary referrals. The rarer causes of facial pain are frequently seen within the clinic making it a valuable teaching clinic for both medical and dental higher surgical trainees and dental undergraduate students. In the development of the facial pain service, links have been made with colleagues in neurosurgery, neuromedicine and palliative care. Weekly clinics, held with neurosurgery, review patients with trigeminal neuralgia requiring surgical treatment. This clinical interest in facial pain forms the basis for some of the research projects that are currently being undertaken.
