I have an intense tooth pain and sensitivity to cold after getting cavitities filled. what can be going on? its been 2 weeks already.

Tooth sensitivity: Sensitivity to cold is often dependent on the type of filling material used. Silver fillings are often sensitive for several weeks, especialy if the are large and/or deep. Cold sensitivity is also often a result if a filling is too high. Check back with your dentist. If the filling is high, it just needs a simple adjustment.

Call your dentist: You may still experience post operative sensitivity. However, to be save please see the dentist to test your tooth nerve.

Be patient: A tooth may be sensitive to cold is fairly common and might last for several weeks after you get a new filling. If this pain persists longer than 3 weeks, you should contact your dentist.

Filling pain: New fillings especially when they are deep, large or are amalgam fillings that conduct hot/cold sensation can cause the nerve of the tooth to be sensitized for awhile. Two weeks is a long time but I have seen it last for months in some cases. However, it is best to speak to your own dentist. If the pain is getting worse, it might require a sedative filling, bite adjustment or Root Canal Therapy.
