Second and third day after wisdom tooth removal , i still have so much pain and my temperature is around 37.7. my doctor wants to wait until she gives antibiotic but im afraid that i might need to start asap. what do you think?

Second Guessing: You are second guessing your dentist, someone who has so much experience in these matters. She does not want to overprescribe antibiotics which over time may result in resistance. You've had a minor surgery and if the extraction was difficult then pain is expected. Has she seen you post-operatively? You may have a dry socket.

Yes take Antibiotic : Antibiotic and pain medication will help ,sooner you take .
