During the Nara period, many Tang artifacts were introduced to Japan from China along with Buddhism, including toothpicks. To this day, Japan still retains the original name for toothpicks, Yangzhi, which is quite poetic. To this day, single-pointed toothpicks with a pointed tip on one end and a pattern on the other end are the most common in Japan, and the patterned ends can be folded off to be used as a temporary toothpick holder to ensure that the tip of the tooth picking is suspended in the air and is not contaminated.
 
A triangular toothpick is a toothpick with a triangular cross-section of the tip tip, which was first introduced in Japan by Creden. With a history dating back to 1917, Credin specializes in the production of oral care products, and its toothpick products are performing well in the market. The common toothpick on the market is a pointed toothpick with a round cross-section, which is not suitable for removing interdental residue, because the gap between the teeth is roughly triangular, and the round pointed toothpick is easy to compress the gums and even cause bleeding after penetrating into the tooth gap to a certain extent, while the triangular toothpick can fit the shape of the tooth gap better and easily remove the residue without pressing the gums.
 
There are two types of triangular toothpicks, triangular toothpicks and triangular interdental toothpicks, both of which are made of Hokkaido birch wood. Birch has a delicate texture, soft luster, and is slightly tougher than common bamboo materials and is not easy to bend. However, the tip of the two toothpicks is very small, and it is easy to break with a little force. The triangular toothpick is slightly clumsy, the flossing port is triangular, the back of the toothpick is square, and the polygonal edges and corners increase the friction and make the grip more stable. The specification of this triangular toothpick is a box of three plates, one board is spliced by 20 toothpicks, which need to be broken for use, a total of 60 toothpicks, which is converted into about 48 yuan, which is slightly expensive.
 
The triangular interdental toothpick is smaller and more delicate, and the back of the toothpick becomes a light sheet shape, which can be used to scrape off stains on the surface of the tooth. A box of triangular interdental toothpicks contains 80 pieces, and the price is also about 48 yuan.
 
In particular, crednet toothpicks come with different scents, such as lemon, nutmeg, mint, etc., which consumers can choose to inspire, bringing a refreshing experience to the flossing process. Smelly toothpicks are not common in the domestic market, and consumers who can afford to shop overseas can try Clearnet toothpicks.
