Hello, I went to the dentist this past Friday to get cavities filled, and the doc gave me wayyy to much Novocain (in my opinion). I was numb all the way past the top of my ear. I have never been given this much novacane before. When I woke up the next morning, my hearing was muffled and it feels like there is water in my ear. I can hear myself in my head. I can clean out the fluid with a Q-Tip, but minutes later, the feeling is back again. Should I be worried? Is there a fix?
