Sensitivity after fillings?

Question:

I had three metal fillings done a couple of days ago, one was quite big, the other two were just little ones. They're quite sensitive to hot and cold at the minute, particularly the bigger one.

This is the first time I've ever had fillings, so I don't know anything about it - how long will the sensitivity last for? And the dentist said that the bigger one was really quite deep and there was a VERY small chance it might actually need a root canal..how will I know whether it does or not?

Answers:
It is normal to experience some hot/cold sensitivity after having fillings placed. Typically if the hot or cold sensitivity lingers for longer that 15 seconds or so this is a sign of an unhealthy nerve in the tooth, therefore you will probably need root canal therapy. You will need to return to your dentist if this continues for longer than 7-10 days after the filling has been placed. Having fillings placed will cause the tooth to have some sensitivity, but only for a limited time. If the tooth becomes very sensitive to bite, spontaneously aches, or keeps you up at nights you will need to return to you dentist, these are signs that you may need a root canal. Good Luck

Other Answers:
The sensitivity is now for ever..

The sensitivty will last quite a while. Rinsing with warm water and mouthwash will help though, and take tylenol if the pain gets out of hand.
