Filling 虫歯

Went dental clinic to fill my decayed tooth (虫歯 in Japanese) today.

I was in total panic when I found out a hole on my tooth last week after my lunch. Made appointment with in-house clinic and I have waited for one week until today. The university dentist said my condition is serious, she recommended me to the dental clinic outside. Without any hesitation, I dashed to the clinic which is recommended by her. Japanese culture is to take off the shoes when someone enter a house, but in dental clinic, I was required to take off my shoes too...weird..

First time do tooth filling in Japan, first I took x-ray (sound serious) on my teeth and then the dentist tried to explain to me my condition now, it sounds very chronic but I can't really understand him by 100%. The conclusion is I have to fill this serious decayed tooth with the nerve removed,and next week I have to come to fill other teeth. There was LCD small TV in front of me when I was waiting for my anesthesia to take effect. It was playing Harry Potter.

I paid 30% for the treatment, around 4500 yen. The rest is bared by insurance. Another hole in my wallet.
