I had a filing with a new dentist recently. It was a bit frightening, because my previous dentists were..... And I have permanent nerve damage now.

Anyway, the dentist really took her time, put "medicine" on the tooth,etc. I had some light pain for about four days and then it went completely away.

I'm not sure how long a new filing might hurt. But be careful. If the X-rays look good, then it very well might not be a dental issue. Perhaps you just need extra time to heal. If it persists without explanation, see another dentist and a neurologist for some ideas. Don't let the new dentist do anything unless he or she has an excellent, clear cut reason to do so...proceed with extreme caution.

Hope all is just fine.
