Emily Chung

Associate Dentist

I graduated from University of Birmingham in 2016, and completed my Dental Foundation Training in Hertfordshire. I then moved onto further training in Peterborough Hospital in the Oral Maxillofacial Surgery (OMFS) department where I carried out complex oral surgical procedures and dealt with facial trauma. Here, I gained a remarkable amount of knowledge and skills working alongside exceptional OMFS Consultants. I now work in general practice and am working towards my Postgraduate Diploma in Aesthetic and Restorative Dentistry. I love to get to know my patients and always do my best to make them feel comfortable. Outside of work, my interests include cycling, bouldering, badminton and gardening.

I qualified from The Royal Dental Hospital, London, in 1981 and after a year in general practice went on to take a masters degree in Periodontology. I then spent three years working in Nigeria before returning to UK to work in practice. I am on the specialist list as a periodontist and currently work as a specialist in practice. I also spend one day a week teaching undergraduates and postgraduates at Kings in the Department of Periodontology.


Deborah Lipman


I qualified from Leeds Dental Institute in 2001, and following a vocational training year in Faringdon, went on to work in general practice in Watlington, South Oxfordshire for 16 years. During this time, the main joy for me was building up long-term relationships with my patients, in a relaxed environment and with a gentle manner.

I enjoy practising all aspects of dentistry, and I have always kept up to date with learning. In 2007, I undertook a postgraduate course, obtaining membership to The Royal College of Surgeons in England.

Away from work, I am married and kept busy with three lively children. In my spare time, my interests are running, swimming and travelling.
