I am 31, 5ft 9 and very healthy, no medical issues. I woke up a couple of days ago with extreme pain and some swelling in my gum, just behind my last molar on my right lower jaw. I have been rinsing with salt and warm water and also using corsodyl mouthwash. The swelling is down now but there appears to be a cavity in the gum and some extra flesh behind the last molar, this is still very painful. There is no bleeding, just excruciating pain around the affected area and beneath my left ear. I have also been experiencing persistent headaches because of this.I tried to get an appointment but i'll have to wait days before I can see a dentist. Kindly prescribe something to relieve the pain and remedy the situation.
