The origin of toothpicks is quite long. Toothpicks have been invented since ancient times. Toothpicks were taken directly from willows in the early days, so they were called "poplar branches". The ancients used them to eliminate bad breath and increase taste. Evolved into the shape of a cylindrical tip.

The traditional toothpick has the following disadvantages. It is a straight cylindrical rod with sharp ends. In use, the straight toothpick is not easy to clean the back of the teeth, and cannot go deep into the gaps between the teeth, resulting in the accumulation of tartar in the gaps, making it lose its purpose of cleaning and hygiene Moreover, wooden soft toothpicks are easy to break and scratch the enamel, so it is not ideal to use.

Therefore, some workers have developed a straight plastic toothpick, but the length of the handle is not enough, it is not easy to operate, and the straight rod body is not easy to penetrate and clean the rear molars, and the sides of the toothpick are too soft to enter the gap between the teeth. Tooth effect is greatly reduced.

Later, some advanced people developed dental floss, but dental floss is still not easy to clean the molars in the posterior region, so food residues and dental calculus are still easy to remain on the molars, so the use effect is limited.

The above-mentioned reasons are all caused by the wrong angle of the toothpick, the handle is too short, it cannot penetrate into the mouth and the back of the teeth, and it can only be inserted into the interdental space on one side during operation. Therefore, there are still many problems to be solved in use.

In view of this, how to solve the cleaning and sanitation of the above-mentioned teeth and interdental gaps, and also take into account the convenience of operation and use, has become the subject of the utility model to be improved.
