Professor Gibson qualified in dentistry and medicine and is professor of medicine in relation to dentistry and honorary consultant in oral medicine at Glasgow University.
He will take over from Professor Trevor Burke, who retired from the board in October after 11 years of service.
Professor John Gibson said: ‘It is a very real pleasure to have been nominated by the board of Dental Protection as the next chair, and to have this position ratified by the Council of Medical Protection Society (MPS).
‘Professor Trevor Burke has filled the role of chair with distinction over the past four years and for much longer as a board member.
‘He leaves the board in a position of strength and I very much look forward to working with the other board members and hugely talented staff over the next months and years.
‘It will be a particular delight to work with the dental director, Kevin Lewis.
‘This is a very challenging time for the dental profession but Dental Protection has a wealth of experience and abilities to offer the profession.
‘I look forward very much to contributing to the forward movement of Dental Protection and MPS.’
The announcement was made at the Premier Symposium on 29 November in London when Professor Gibson delivered a lecture entitled ‘Where medicine meets dentistry’.
Kevin Lewis said: ‘We are extremely lucky to have such a respected member of the international dental community as the new chair of our board of directors.
‘Professor Gibson’s knowledge of both the medical and dental aspects of clinical treatment, his many years of experience of General Dental Council Fitness to Practise committees and his international experience equip him perfectly for the role.
‘Dental Protection’s Edinburgh office is close at hand and his ex-officio seat on the MPS Council will make him a regular visitor to the other offices in both London and Leeds.’
