A person's life, to taste a lot of ups and downs. I like sweetness best, but maybe I just love sweetness too much. My beautiful teeth turned into cavities. Who made me too greedy? Seeing colorful candy, I can't help but try one. Milk candy, fruity candy, chocolate … As long as it is sweet, I have no resistance. Smooth and sweet sugar makes me want to eat again. Who made me too lazy? Eat sugar in the morning without gargling, and eat sugar at night without brushing your teeth. Eat sugar every day, always eat sugar. Beautiful teeth can't stand it, and they become cavities. I have two cavities. Please follow me to explore.

My first tooth decay was at the age of four. At that time, I didn't know anything. I ate sugar. At first, my crystal clear teeth seemed to be sprinkled with black sesame seeds by angels. That's because I didn't feel bad at all, and I didn't even notice it. Gradually, sesame is getting bigger and bigger! Unexpectedly, it slowly turned into a black mung bean. Sometimes it may be a strange feeling to chew and stuff it into the bean pit. Then, it becomes like soybeans, and it hurts when it touches the teeth of insects when eating. I have no choice but to bear the heavy responsibility of eating with only a few front teeth left. Finally, it became a big black bean, which always hurts for a long time. In the end, the worm tooth is like a dangerous house in a rainstorm, as if it will crack at any time. Once, my mother bought some cherries, which were big, full and attractive. I picked up one and bit it. Ah! ! ! Then came the screams of killing pigs. Then spit out a few big black things. Mom asked what was wrong. I cried and said "teeth" and "my teeth". When my mother saw it, she was surprised and opened my mouth. There are five decayed teeth, and all I just spit out is a bad tooth. It's dark and smelly. My mother took me to the hospital at once. Along the way, I cried and said "no, no". Mom says your teeth will rot if you don't go. Along the way, I felt as if there were 25 rabbits scratching their hearts. Alas, I hate dental diseases by nature, and I always feel that dental diseases are particularly painful. My mother took me to the dentist and said, "Show the doctor why your teeth are black." My teeth are badly decayed. The doctor said, "If I come late in January, I will lose my tooth." . A familiar and horrible smell of alcohol came to my face, and the dental department turned on the air conditioner, which was so thick. There was someone in the chair where the tooth was pulled out, and my mother and I were reading on the low stool. I was amused by the joke. "Please look at this tooth for my daughter." Mother said with a dry cough. "Oh, this tooth is broken." Not good? What do you mean? Tooth decay "Sister, are you worried?" "Yes!" "Ha ha, this tooth is black because it can't get nutrition." Hearing this, I thought: What a wonderful doctor! Unconsciously, I let my guard down. Mother said:

"Lulu, can this doctor cure you?"

"no! Didn't we agree not to take advantage of others? ! "

"Hey, let the doctor have a look!"

"No, no! Look at that tooth extractor, it's terrible! "

"No pain, you are 4 years old, and you are afraid of tooth extraction!"

"555555, I don't want it if I say no!"

"Sister, be quiet and don't move!"
