I had had …a… toothache for several days, but just hadn’t enough courage to go to the…… dentist. As …a… matter of fact I went twice, but just as I got on his doorstep and was going to ring the…… bell, the…… toothache seemed to have gone away, so I went home again. But at last I had to go back, and this time I rang the…… bell and was shown into the… waiting-room. There were …a… number of magazines there, and I had just go into the…… middle of …an… exciting story when …the… maid came in to say Mr. Puller was ready to see me. I’ll have to wait for the…… next toothache to finish that story! Well, I went into the…… surgery (зубоврачебный кабинет) and he told me to sit in a…… chair, and then he had …a… look at the…… inside on my mouth. He put a…… little mirror on a…… long handle inside my mouth and said, “I’m afraid we can’t save that one, it will have to come out. I’ll just give you an…… injection.” So he filled a…… syringe (шприц) with a…… liquid. I felt a…… little prick on the…… gum (десна) and that was all. Then he waited for a… minute or so. Then he took an…… instrument, got hold of my tooth, gave a… twist, then …a… quick pull, and the…… tooth was out. He said, “There’s the…… tooth, a…… very nasty one.” “May I have …the… tooth, please?” I said. “It has worried me …a… good deal for the…… last week, and so now I am going to put it on my dressing-table and watch it ache.”
