My broken back tooth. Two days ago, during I had a dinner with my wife, I felt the severe toothache on my right upper back tooth. I found that a portion of tooth was broken. I called to the dentist to know until when they opened. The nurse said that they already full booked that day. Therefore, I could not see the dentist. In stead, I booked my reservation on the next day. After that day, I went to the dentist. The dentist checked my tooth. She ordered a treatment. I had to visit the dentist for six or seven times to treat my broken tooth. She killed my nerve in that tooth not to feel the toothache. And then, she would cover gold or ceramic material on that tooth to meet the height with the teeth of side. The medical fee was too expensive. It was about 550,000 won. Two months ago, the opposite site thing was also small broken. I think the duration years of teeth is forty years. I can not drink the cold water and the ice creams. Whenever I have them, I feel cold on the gum. In the Korean proverb, the good teeth are one of the biggest happies. I definitely agree with it.
