What can I do or what should be done regarding my situation? Do I talk to him before the corrective surgery or after?

I had my wisdom teeth removed. One was very impacted and proved to be complicated. The Dr said he had to break it 25 times to get it out. He took an xray afterwards to show there was nothing remaining. A couple of days later, I am in excruciating pain and it turns out that I have a dry socket. I go in for him to fix it and he puts a dressing on the wound. I'm put on more meds and antibiotics. My swelling goes down then out of nowhere, my cheek gets swollen again. I go see the DR and it is infected again. Now, this has happened a total of 4 times and he schedules me for a debridement surgery for this week (at NO charge). I had to go through a lot and miss alot of work because of this surgery, more than the average tooth extraction patient. I feel that it is unfair that I have to pay $875 for the 1st surgery. Because my insurance benefits were about to expire, I had to find a dr to do the surgery right away. When they told me it was $875 outofpocket, I was like WHY so much? The lady explained that my insurance only covers 60 percent. Never did she say she they were out of network. I want to tell the DR. that he needs to lower the price. Do I tell him this before the surgery this week
