The composition of decayed teeth is 500 words

Tooth decay is not caused by dental caries, but the food residue left in the unclean area of the tooth surface. Bacteria such as Streptococcus mutans and Gram-positive cocci make it decay to produce acid, which decalcifies teeth to form tooth decay, which is called tooth decay. Let's take a look at the 500-word composition of Tooth Cavity. Welcome to read the reference.

Tooth decay composition 500 words 1 "Hum! This worm tooth is really annoying! "

You must ask, what's the matter? Of course, it is this scourge-the "good thing" done by worm teeth. Rugged, ugly and rickety. After dinner, it hides its leaves like a miser. Every time I settle accounts with him with Wuzhishan, his loose worm tooth actually sticks to the front of the dish like a shield, and I can't help it. No, I can't let it continue to be violent. In order to eradicate this scourge, I took the initiative to launch two campaigns.

Battle 1: "Tough guy" storm

I deliberately asked my mother to buy more nuts, so that these "tough guys" forced her to take the initiative to quit the "historical stage." But whether you eat melon seeds or chew peanuts, you are firm. Facts have proved that hard attack is useless.

Battle result: we lost.

Battle 2: "Flood"

Hard is soft. I am not afraid that you will not accept it. I poured water into my mouth, ready to attack with water. I shook my head hard from the beginning. "Dongting Lake" turned into a "sea", turning up waves and attacking the teeth of insects. It's no use. Then try harder. I shook my head violently, and the "sea" became the "Qiantang River", and a series of "tides" attacked the teeth of insects. Alas! Why can't it come down? I didn't lose my tooth, so I felt dizzy and swollen.

Battle result: I failed again.

I am a little unwilling, and I really want my mother to take me to pull it out, but my mother has never had time. One day, I touched the rickety tooth with my hand, and my tongue tilted upward, as if something had fallen into my mouth and I felt that my mouth was leaking. It turned out that the tooth that bothered me day and night fell out, and I was ecstatic at once.

Haha, I have eliminated this scourge!

A child my age is about to change his teeth. Under normal circumstances, changing teeth is just a gentle pull.

This morning, my mother dragged me to the dentist for tooth extraction. This time, it's not an ordinary tooth, but a big tooth half eaten by a bug. Along the way, I repeatedly licked my big tooth that had been "corroded" by tooth worms. When I went to have my teeth filled last year, the doctor said that the cavity was too deep to be filled, and I would pull it out next time it was loose. Now, I have new teeth on my decayed teeth, so I have to pull them out.

I haven't pulled out my teeth, so I don't know if it hurts. Well, we have to try. My heart is full of fear.

When I entered the dentist, there were many people, most of them were children like me, and some middle-aged people waited for a long time before it was my turn.

I was sitting in the chair where my teeth were extracted. The doctor looked at my mouth and knocked my decayed teeth with pliers, saying that it was too strong to be anesthetized. I froze, and my heart kept racing. I heard that people who play anesthetic are stupid. I was in a hurry and kept asking the doctor, "Will it hurt if I don't play anesthetic?" "It hurts, you can't stand it, you have to play anesthetic." "Will it be stupid?" "No, it's to numb your teeth." I am afraid of both pain and stupidity. It's so contradictory. The doctor calmly brought an anesthetic needle and injected it into my gums. "Ah," I couldn't help crying, tears swirling in my eyes. The doctor gave me two injections in a row, and I couldn't help it anymore, so I brushed away my tears. After the anesthetic, half of my mouth was paralyzed and I didn't feel anything. The doctor pulled out my tooth, but I didn't feel anything. All I know is that doctors have been studying it for a long time.

It's hard to eat when a decayed tooth is pulled out. I haven't recovered my mouth, and I can't even speak. It's time for dinner. I can't eat a big table of my favorite dishes at grandma's house, but I can only eat some porridge specially made by grandma for me.

Alas, it hurts to pull out a decayed tooth. I'll never pull out my teeth again! "Good teeth and good appetite" can not only eat delicious food, but also suffer less and save time. I will protect my teeth, rinse my mouth and brush my teeth frequently.
