About

Dr Sedef Sera Hepdarcan Sirman holds a PhD in Orthodontics and is a GDC-registered specialist in both fixed and removable orthodontic appliances. Her particular area of distinction lies in lingual orthodontics — braces that are fitted to the inner surface of the teeth, rendering them entirely invisible from the front. She is one of a relatively small number of clinicians in London with full certification in both the WIN and Incognito lingual systems.

An accredited Invisalign provider, Dr Hepdarcan Sirman combines exceptional clinical precision with a genuine artistic sensibility for facial proportion and smile aesthetics. She works closely with patients to develop treatment plans that achieve not merely straighter teeth, but smiles that are genuinely harmonious — balanced in proportion and suited to the individual’s facial structure.

All orthodontic treatment at DentAkademi London is planned and managed directly by Dr Hepdarcan Sirman. She sees every patient at every appointment — from the initial digital assessment through to final retention. Her caseload spans teenagers, adults in their 30s and 40s, and complex cases involving pre- and post-surgical orthodontic preparation for patients undergoing orthognathic jaw surgery with Mr Baha Bagdadi.

Why Choose a GDC Specialist Orthodontist

In the UK, the title “specialist orthodontist” is legally protected. Only dentists who have completed an additional three years of postgraduate training specifically in orthodontics may use it, and they must appear on the GDC Specialist List. This is distinct from a general dentist who holds an Invisalign certificate — the scope of training, clinical judgement and case complexity that a specialist manages is substantially greater.

For growing patients, adults with more complex bite issues, or anyone considering lingual braces or combined orthodontic-surgical treatment, specialist supervision is not a preference — it is a clinical necessity.
