Fillings and pain

I had a dental appointment a few weeks ago where an an x-ray showed I had developed two cavities. This past week I went to have them filled. Everything during the procedure seemed to be fine and I had the usual five hours of waiting for the numbness to wear off. I thought that was the end of it. But a couple days later I started getting pain when chewing in that area, which is something I’ve never experienced after getting cavities filled in the past. It’s not a constant problem but does seem to be affected by temperature, especially hot foods. The Scientist had this experience earlier this year and it continued for quite a few weeks after he had the initial dental work so I am not too encouraged about the prospects of this disappearing any time soon. He did some research at the time and discovered there have been many complaints of this sort of pain with the newer types of fillings due to them being more conductive than the older style ones. I’ve also noted that I’m unable to get dental floss between the teeth in the area so may end up back to have that sorted out some time. The dentist apparently was quite surprised by the pain when the Scientist went back to him so I wonder what he will say if I end up returning too.
