The oral manifestation of leukaemia can be summarized as follows.
In acute leukaemia- localized or generalized gingival hyperplasia is generally observed. It mainly affects the interdental papillae and the marginal gingiva.
Oral malodor (halitosis) is a problem of all ages.
The most common cause of the oral malodor is the poor oral hygiene. Due to poor oral hygiene, a large number of bacteria belonging to different species make their home in the mouth. They survive on the food particles entangled in between the teeth and as a by-product, produce different substances like Sulphides, Mercaptans and Amines in gas form. These gases are perceived as bad breath by other people.
