Tooth Pain After a Filling – Why Does My Tooth Hurt After Filling?


Tooth Pain After a Filling


Filling is recommended by the dentist for a mild to moderate decayed tooth. Filling is safe and prevents further tooth structure from decaying. Filing is a very regular process and generally does not cause any post treatment problems. But some people feel discomfort or sensitivity after the treatment.

In most of the cases sensitivity will be normal and resolve within a week. If you are feeling severe pain, swelling or sensitivity that won’t resolve you need to visit your dentist to find out the cause and further treatment.

Here we are going to discuss some possible causes of pain or sensitivity after your filling treatment.


Procedure for Dental Filling:
a very small decay does not require local anesthesia. For a patient’s comfort we need to numb the tooth with mild to moderate cavity size as during the cleaning you feel sensation.

Dentists will remove all the decayed portions with a drill and once the healthy sound tooth structure fills it with tooth colored composite or silver filling. Nowadays composite is the choice of material for dental filling.

Slight sensitivity or kind of new sensation you can feel in your teeth or in surrounding parts. Which is quite normal, and you get adjusted with it in some days. With consumption of very cold or hot beverages you can feel a sharp sensation which will go away within a second.

Hyperactive or Inflamed Nerve:

Enamel is a natural protective layer of the tooth. When cavities start it affects the enamel and dentin of teeth. Deeper cavity irritates the nerve so sensitivity after deep filling is most common.

Another cause for sensitivity after filling is the procedure itself. During the removal of decay due high-speed drilling, it will temporarily aggravate the nerve.

Once inflamed nerves get healed you will not feel sensitivity or any unusual feeling. It will be the same as your other teeth.

High Point or Incorrect Bite:
After the filling procedure the dentist will correct the height of filling according to your bite with finishing and polishing. If the filling is left a little bit high or the patient is not able to close teeth properly it can cause more pressure on the tooth. Due to this you can feel pain or sensitivity in filling.

If this is the cause, the dentist will again evaluate your bite and do correction.

Pulpitis: It is an inflammation of the pulp(nerve) of the tooth. Which causes severe pain or sensitivity.

  • Smaller size cavities generally do not affect nerves but with deep filling it can happen.

  • Tooth with history of trauma
  • Very deep cavity near to pulp
Need to do refilling or root canal treatment to treat the affected nerve.

Other tooth: as the adjacent tooth innervated with the same nerve sometimes the patient is not able to distinguish which tooth is giving you trouble.

This generally happens in patients with multiple decay or dental issues.

If the tooth sensitivity does not resolve in some days after filling, visit your dentist to rule out the cause.
