Hi Doctor: I had some pain on the right side of my jaw. I thought it was either the top or bottom of my mouth where the pain was coming from. The Dentist sent me home to locate the pain. The very next day i went back and told the Dentist where i thought the pain was coming from. The Dentist said, "do you want to re-do the filling or root canal. We decided to do the filling, i don't remember exactly where the Novocaine was injected, but one went into my cheek.The pain was getting better, but i experienced pain from the right side of my jaw after eating. i went back to the Dentist and he used the drill to even out my bite on that side, it felt much better, the hygienist said that my mouth will be sore for a few more weeks, but i noticed my gum feels really sore above my tooth when I touch it. Can you tell me what is going on? I know they put cardboard in my mouth to hold it open when the procedure was done, but i would of preferred cotton. The cardboard was hard on my gums too, it feels like a bump there. The tooth fixed was upper right all the way in the back, but not wisdom tooth
