Teeth cleaning twig
Chew sticks are twigs with a frayed end used to brush against the teeth, while the other end can be used as a toothpick. The earliest chew sticks have been dated to Babylonia in 3500 BC and an Egyptian tomb from 3000 BC; they are mentioned in Chinese records dating from 1600 BC  and in the Tipitaka, the Buddhist Canon, purported to be giving account of events which took place in the North-Western India around 5th century BCE.
In Africa, chew sticks are made from the tree Salvadora persica, also known as the "toothbrush tree." In Islam, this tree is traditionally used to create a chew stick called miswak, as frequently advocated for in the hadith (written traditions relating to the life of Muhammad).
Traditional Sikhs still use datun today as it is written in their scriptures - “Datun kare neet net nda dukh pawe lal jee” -Guru Gobind Singh
“Dear/beloved , natural twig brush everyday and pains you shall never get.” - Guru Gobind Singh (Tankhah Naama- Guru Gobind Singh written down By Bhai Nandala)
Sikhs strive to do good deeds for the environment so cleaning your teeth in a natural way is a good eco-deed as it is renewable and without plastic packaging.
