When there were no toothbrush and toothpaste, Chinese people use toothpick to clean their teeth. Toothpick is probably the oldest instrument for dental cleaning.
The method is like this : One end of the toothpick was chewed into and became softened and brush-like while the opposite end was pointed and used as a pick to clean food and debris from between the teeth. The twigs used were carefully chosen from aromatic trees that had the ability to clean and freshen the mouth. The earliest literature showing the use of these twigs is found in Chinese literature at around 1600 BC.

世界不少古老文明皆曾有以嫩枝或小木片揉刷牙齒的做法，另一種常見的方法是以小蘇打或白堊揉齒。
據美國牙醫學會的資料表示，世上第一把牙刷由中國皇帝明孝宗於1498年發明，方法是把短硬的豬猔毛插進一支骨製手把上。西方傳統清潔牙齒的方法是用一塊碎布揉刷牙齒，此方法至少於古羅馬時代已經存在。

Also Chinese people use something like tongue scraper to clean their tongue i.e. to remove the whitish-gray layer on the tongue (刮利胎).
