Many people experience sensitivity after getting a dental filling.  As I’ve mentioned, sometimes this sensitivity can be attributed to a high filling.

A tooth can also be sensitive after a filling due to other reasons.  Here are a few reasons why your tooth might be sensitive after a filling and what you can do about it.

Why Your Tooth Is Sensitive After a Filling

Tooth Sensitive After FillingWhen you sit down in the dental chair to get a filling, one of the first things that the dentist will do is to give you an anesthetic injection to make it so you can’t feel the pain of the upcoming dental procedure.

When your dentist goes in and removes the decay from your tooth, it is very painful and can traumatize the tooth.  Luckily, due to the anesthetic, you usually don’t feel the pain caused by this process of repairing your tooth.  This is the main cause of tooth sensitivity after a filling — your body is simply telling you that the tooth was traumatized.

The bigger your cavity (and resulting filling), the more likely it is that you will experience sensitivity after the filling is done.

Other than trauma, there are a few other reasons why you might experience a sensitive tooth after a filling:

  • If you have a high filling
  • If you have a large metal filling – it can conduct cold more quickly to the nerve of the tooth.  Also, if your dentist didn’t use a material to seal the tiny tubes that travel from the filling to the nerve, it can cause increased sensitivity.
  • If you have a large white filling – if it is placed too quickly, it can cause stress on the surrounding tooth structure

What to Do When Your Tooth Is Sensitive After a Filling

In most cases, you don’t need to do anything — your dental pulp will gradually insulate itself from the filling, which should cause the sensitivity to go away.  This process can take anywhere from one to several weeks.

If your sensitivity does not resolve and feels like it’s getting worse, then you should see your dentist.  It could be that you have a high filling, or that the filling needs to be redone.

Conclusion

In summary, know that having a sensitive tooth after a filling is completely normal.  Sensitivity that gets worse is not normal.  Worsening sensitivity is a sign that something is wrong and you should see your dentist to determine the problem so that a solution can be found.
