I don't know what happened these days? My teeth suddenly hurt. It's killing! As the saying goes, "toothache is not a disease. It will kill people if it hurts."
After these days, I searched the Internet and asked my parents what was the cause of toothache? Finally I know why I have toothache. It's because I'm on fire! I usually eat too much hot junk food, and I didn't brush my teeth clean. Now, I can't eat now. I really regret that I ate too much junk food and didn't brush my teeth, which led to my end now.
Finally, I would advise you not to eat those hot junk food, and to brush your teeth carefully instead of casually. If you don't want toothache, listen to me!
