Can you catch parasites in your teeth? Can you explain the following?

Hello. Toothworm does not exist. Worm teeth are also called dental caries. It is a phenomenon that the teeth are corroded by too sour or too sweet food and bacteria, and the teeth turn black and deteriorate. But there are absolutely no bugs in the teeth.

When I was a child, I saw what you said about "eye worms". About 20 years ago, two middle-aged women in Anhui Province caught insects in people's eyes. When you see an old man or a child, ask if your eyes are uncomfortable. Then they roll a round bamboo chopstick on people's upper and lower eyelids. The other hand is pulling with chopsticks. Soon a white linear thing appeared. " The money in 5 yuan is basically equivalent to that in 50 yuan now. This has fooled many people. Later, a doctor passed by and shouted don't be fooled. He drove away two women. The doctor says there are no bugs in people's eyes. There is a "beautiful nematode" that may live in people's eyes. But it can only be treated by surgery. You can never turn it out with chopsticks. ..

So catching bugs from eyes is a quack trick.
