A few decades back before the invasion of cheap toothbrushes and toothpastes most Indians used to brush their teeth with datuns. Datuns are twigs from either the keekar tree or neem tree. One end of the twig was chewed till a sort of brush was formed and then teeth were cleaned with it.
Perhaps the datun has vanished inside cities but on the peripheries close to villages people still use this as a morning ritual.
Here this girl is chewing on a datum and taking a branch of some tree perhaps to use both as firewood and as a source for datuns.
