Natalie Siriwardena trained as a paediatric nurse and worked as a staff nurse at west Middlesex Hospital. Her passion for further learning led her to train as a dental nurse and then onwards as a dental hygienist at the Eastman Dental Hospital, where she completed her diploma course from the Royal College of Surgeons in 2014.

Natalie regularly performs hygiene therapy and more advanced non-surgical periodontal treatments under local anaesthetic for patients suffering with advanced periodontal disease. She aims to continue training within her field.
