Going to see a dentist

Recently, I have felt pain in my teeth, so I went to see a dentist in the afternoon. When I arrived at a dental clinic, I noticed that there was a dentist whom I don't know. He said he is a son of a dentist whom I know and his father is in the hospital now. That's why, he manage to run his dental clinic in stead of his father for a while because he is also a dentist. When I had his examine my teeth, he said there were two cavities which need treatment. I had one of my teeth treated this time. I will go to see a dentist next Wednesday. To be honest, I don't want to wait until next week, but it seems that he has another working place and he opens his dental clinic only on Wednesday. I noticed that I ran out of money at the time of payment. He was so kind that he let me pay next Wednesday. I’m grateful for his kindness.
