The pathogenesis of the disease is not well established, but is believed to be multifactorial. Areca nut chewing is considered as the major etiology amongst all. Children indulge in habit of chewing areca nuts due to its easy availability of different forms of multicolored attractive areca nut pouches in markets. Other factors involved in the consumption of Areca nut are levels of awareness, household environment, peer pressure, low cost, etc.
