I had the same problem after my Amalgams were replaced. I kept waiting for the nerve to "settle down" but it kept hurting day after day. Finally I went to see another dentist and come to find out the new filling had developed a crack or hole in the top and food, etc was getting in.
It was a large filling in a molar and the new dentist ended up having to crown it. I'm so thankful I went to get it looked at instead of continuing to wait! I found the new dentist by calling the Dr Huggins number and asking for a referral. I found a fantastic dentist that way! I highly recommend going to them for a referral!!
Good luck, I know how anxious it feels to wait and hope it'll get better on it's own.
