Oh thoses Dentists

I have been having a tooth ache, Oh for about a month now. This past weekend it got so bad I couldn't hardly stand it. Early Monday morning I called our dentist and I couldn't get in until Wednesday. I found some pain drugs leftover from when Lindsay had her wisdom teeth removed earlier in the year so I started taking them. These got me to Wednesday. I get to the dentist and I had a broken filling. Let me tell you there was a couple of times I thought I dying. Just put me out of my misery. He numbed me up and drilled out that old filling and decided I needed a root canel. I have to say that I can now eat on both sides of my mouth, I can swish cold water in my mouth and it not hurt. I feel so much better. How can 1 little filling cause so much pain.
