I went to the Dentist on Tuesday and he pulled out my upper right wisdom tooth. He did not prescribe any antibiotics because he said there were no signs of infection. On Thursday, I woke up with tons of pain in my throat, ear and mouth on the right side. I called him and went back in to see him, and he claimed it was dry socket. He placed some sort of cream medication in the hole and cleaned it using salt water. Today, I woke up and the pain was still there. I figured this was normal since I should still be sore, however I notcied swelling along with a yellow colored area around the hole. I figured this to be infection. The pain is excrutiating, however if an infection is present, I don't think it is too bad. Can this infection heal on it's own without the use of antibiotics? It has been almost 4 days after the extraction....
