Dog Lovers Or Vets Please ANSWER. URGENT AND IMPORTANT?

I had a consultation with the vet about getting dental work for my dog. The vet said he will need to take out 1 to 5 teeth and just remove the plaque. We made an appointment a week later. After picking up my dog( a Pomeranian), he looked dazed and confused. His left eye was blood shot red. It was literally popping out of his eye socket. The vet told me he removed some teeth and gave us painkillers for the dog. When we got home and reviewed the papers. The vet took out 15 teeth! 15!!! Yes my dog's teeth were bad but they didn't hurt him! We just wanted to get rid of his smelly breath! My dog is in so much pain now. He keeps crying and its a battle trying to give him medicine. My poor dog is suffering. The vet removed 2 of his front teeth so now when my dog opens his mouth up, he looks toothless. I argued with the vet this morning. He said that he didnt want to keep the dog under anesthesia so thats why he couldnt call and he took out 15 teeth because they were "really bad". Is it normal that a vet took out 15 teeth without consulting me first? What should i do?
