Have they done a ct scan or blood work to see if the bone is infected? I had osteomyelitis in the lower jaw after an extraction. I went through dry socket and a month latter the dentist gave me antibiotics but it was to late. the Infection went into the bone and I have had health issue ever since. The pain was excruciating. I am a diabetic and would not wish what I have been through on anyone. If it does not get better ask them for blood work and a ct scan to see what is going on.
