Sugarcane ripens in winter and has a tonic effect. Sugar cane is not only nutritious, but also rich in fiber, which can play a role in cleaning teeth. Nibbling on sugarcane also has the effect of strengthening teeth.
Chinese medicine believes that sugar cane enters the lungs and stomach. At the same time as quenching hunger, it can also quench thirst. Therefore, "lidong cane" has always been an old practice that hipsters love to follow. Moreover, bagasse, which is rich in plant fiber, can be described as the "cleaner" of the mouth, which is repeatedly chewed in the mouth, which can sweep away the dirt remaining in the mouth, thus making our teeth tougher.

Here, you can see the difference between the use of "teeth" and "pain" in Mandarin and Chaoyu. Mandarin mostly uses "tooth", and Chaoyu uses "tooth", such as "toothache" corresponding to "toothache", "tooth gap" corresponding to "tooth gap", "brushing teeth" corresponding to "gargling teeth" and so on.
You can look at the explanation in the "Explanation of Words":
Teeth: "Mouth broken bone also." Like the shape of a mouth, it stops sound. ”
"Broken bones in the mouth" means being able to bite off bones. The incisors (front teeth) and sharp teeth (tiger teeth) in our teeth play a role in biting through food, and these two types of teeth are collectively called anterior teeth, so "teeth" refer to the front teeth.
Tooth: "The teeth are also like the shape of the upper and lower levels." ”
"Oyster teeth" refers to strong teeth. That is, people often say that the big teeth and the back teeth. The "shape of the upper and lower phases" refers to the state in which the tips of the teeth are staggered after the teeth bite. Therefore, "teeth" refers to the back teeth.
Originally the teeth are common names, commonly have cold lips, lips and teeth are interdependent, he foot hanging teeth, no teeth unforgettable.
In modern times, although Mandarin has used "tooth", the Chao language still retains the name "tooth".
