When the tooth becomes damaged or broken, a filling may be required. A filling helps restore the structure of the teeth and prevents further damage. Additionally, teeth need fillings when a person has a cavity. Either way, fillings should restore teeth and alleviate pain and discomfort. In some cases, a filling may still hurt. If so, here is everything you need to know.

Is it common for a tooth to hurt after getting a filling?

It can be common to experience some pain or sensitivity after getting a filling at the dentist. This is often due to the impact during the treatment and all of the drilling involved. However, the pain or discomfort should fade after a day or two.

If the pain does not subside, then there may be further complications.

What can cause a tooth to hurt after a filling?

Although pain and discomfort can be common a few days after the treatment, they should not continue. If the pain does persist after getting a filling, then here might be why:

The type of filling

There are several types of fillings your dentist can use. The most common ones that usually cause pain are those made of composite resin. These can sometimes shrink after being placed into the tooth. If the resin shrinks, it can create a small gap, which can cause pain and sensitivity.

If this occurs, it will be best to go back to the dentist to replace or refill the gap.


You may have received the right filling. However, the filling may not have been placed right. If not, you may experience pain and discomfort until you get it sorted.

A malocclusion will prevent you from biting properly. It often causes more discomfort than pain. Either way, it is frustrating to live with. It should be seen by your dentist so that they can adjust the height of the filling to make your bite normal again.

Galvanic shock

Seeing as there is various type of fillings available, many come in different metal materials. If you get a silver filling in one tooth and gold in the next one, or one opposite, then it may cause galvanic shock due to the electric current reaction.

Galvanic shock is rare. However, it can happen. Whenever you experience pain, ensure to consult your dentist to see if the metal materials are the cause of the problem.

Exposed pulp

If your nerve is damaged underneath the filling, your gum can become inflamed and cause pain. In this case, you may need to get the filling removed and have root canal treatment.

What to do about the pain

If you are experiencing pain after a filling, it would be best to maintain regular brushing, flossing, and mouthwash twice a day. This will ensure the removal of plaque and food from the teeth. The health of your teeth is essential, and pain could be a sign of further concern and a lack of oral health.

If tooth pain does persist after getting a filling, ensure to visit your dentist for an assessment and effective treatment.
