Engineering:Teeth cleaning twig
A teeth cleaning twig or datun is a tool made from a twig from a tree. It can help to prevent tooth decay and gum disease.
History
Chew sticks are twigs or roots of certain plants that are chewed until one end is frayed. This end can be used to brush against the teeth,[1] while the other end can be used as a toothpick.[2] Most commonly plants are used that have a high content of tannins (astringent and antibacterial) or other compounds that benefit the health of gums and teeth.[3] The earliest chew sticks have been dated to Babylonia in 3500 BC[2] and an Egyptian tomb from 3000 BC;[1] they are mentioned in Chinese records dating from 1600 BC[2] and in the Tipitaka,[4] the Buddhist Canon, purported to be giving account of events which took place in the north-western India around the 5th century BC.
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).[5]
Even today, many Indians in rural areas use neem twigs for brushing every morning. It has antibacterial properties and helps keep gums healthy. It is known to reduce many gum related diseases.
Traditional Sikhs still use datun today as it is written in their scriptures:
ਦਾਤਨ ਕਰੇ ਨਿਤ ਨੀਤ ਨਾ ਦੁਖ ਪਾਵੈ ਲਾਲ ਜੀ ॥ (੨੩)
("Dear/beloved, natural twig brush everyday and pains you shall never get. (23)")

Teeth cleaning twigs can be obtained from a variety of tree species. Although many trees are used in the production of teeth cleaning twigs, some trees are better suited to clean and protect the teeth, due to the chemical composition of the plant parts. The tree species are:[6][7][8][9][10][11]

Carrying
Many companies produce special cases for carrying, storing and protecting chew sticks, known popularly as "miswak holders".
Advantages
When compared to toothbrushes, teeth cleaning twigs have several advantages:
- More ecological in its life-cycle
- Lower cost (0–16% of the cost of a toothbrush[12])
- Independence from external supplier if made at home from privately owned trees
- Low maintenance, with some twigs needing moistening with water if they become dry, to ensure the end is soft. The end may be cut afresh to ensure hygiene, and should not be stored near a sink. The twig is replaced every few weeks to maintain proper hygiene.
- No need for toothpaste
On the other hand, different species of trees have various levels of hardness just as synthetic toothbrushes would, so careful selection of the right hardness is required before use. Excessive scrubbing too can also bring the risk of gum damage, though this is a concern for plastic toothbrushes as well.[12]
