The health hazards associated with chronic periodontitis (gum disease) extend way beyond the mouth. For years people have been warned that persistent periodontitis can cause heart disease. Now a new study suggests that gum disease may also be a risk factor for cancers of the head and neck.
With each millimetre of alveolar bone loss, the risk of head and neck cancer increased more than 4-fold, the report indicates. The link was seen even in subjects who had never used tobacco and alcohol. - (Reuters Health, September 2009)
