All guidelines including NICE1 and those from the USA,2 ,3 Europe4 and Australia5 ,6 agree that regular dental surveillance is essential to promote good oral hygiene, reduce the need for invasive dental procedures and reduce the risk of infective endocarditis. Around 40% of cases of infective endocarditis are caused by oral bacteria. Although these may enter the circulation during invasive dental procedures there is also evidence that transient bacteraemia with oral organisms occurs during daily activities such as chewing food and tooth brushing. The size and frequency of the bacteraemia are significantly greater in those with poor oral hygiene.7
