[208] Bhikkhus, there are these five disadvantages (ādīnava) of not chewing tooth-wood (dantakaṭṭha). What five? It is bad for the eyes; the mouth becomes foul-smelling; the channels that convey taste (rasaharaṇī) are not cleansed; bile and phlegm envelop one's food; one's food does not agree with one. These, bhikkhus, are the five disadvantages of not chewing tooth-wood.
