Why Is My Tooth Sensitive After Getting a Filling?

June 19, 2017
Posted By: Terry Imbach

Thanks to modern equipment and advanced techniques, getting a filling on your tooth is easy and painless. You’ll be able to eat, drink, and brush right after the procedure with no issue. However, in some patients, once the anesthesia wears off, they may find that their new filling is sensitive. Before freaking out and blaming the dentist for a botched job, you should keep in mind that this is a very common side effect of fillings.

Causes of Tooth Sensitivity After a Filling

There’s not one thing that causes your tooth to feel sensitive after a filling. Often it’s a combination of factors that result in a slightly painful feeling. These can include:

  • Pulpitis, which is when the nerve of your tooth is slightly agitated by the trauma of drilling.
  • An uneven bite, which occurs when the filling is placed too high, causing the surface of your tooth to be uneven when biting down.
  • A deep filling, since the closer a filling is to the nerve, the greater the chance of sensitivity.

Sometimes, even the material used in the filling can cause some sensitivity. To know for sure what’s causing your problems, it’s important to schedule an appointment with your dentist so that they can examine the filling closer.

Types of Tooth Sensitivity

Not all tooth sensitivity is the same. Just as there can be different causes of sensitivity, there can also be different forms of sensitivity. These can include:

  • Pain when touching or biting your teeth together
  • Pain when exposed to hot or cold
  • A constant, throbbing pain that never really goes away
  • Pain in the teeth surrounding the original filling
  • Galvanic shock, which is caused by an electric current when you touch your teeth together

Take note of when your pain occurs and record any triggers. If the pain doesn’t get better, having this information can go a long way in helping your dentist make an accurate diagnosis.

How Long Will My Tooth Sensitivity Last?

Generally, tooth sensitivity from fillings only lasts a few days to a few weeks after the procedure. This gives your mouth enough time to adjust to the changes. However, if you are having pain or sensitivity for longer than a week, it’s a good idea to give your dentist a call. The filling may have been too close to the pulp or your bite might be off, meaning that the pain won’t go away unless the dentist makes some adjustments.
