If you’re experiencing tooth sensitivity after a filling, it’s probably not a cause for concern.
Most people experience minor sensitivity after having a cavity filled. It usually gets better in a few days.
Call your dentist immediately if you’re in extreme pain or have other symptoms, like fever or swelling.
These symptoms aren’t typical after a filling. They may signify a more serious problem.
It’s normal and common for your teeth to be mildly sensitive after a filling procedure. This is because the dental drill can aggravate the nerve inside the tooth.
After the numbness wears off, it’s normal to feel:
Common triggers of tooth sensitivity after a filling include:
Tooth sensitivity should subside within 2 to 4 weeks after the filling. Call your dentist if you still have sensitive teeth after 4 weeks or if the pain worsens.

Temporary sensitivity after a new filling is common. If tooth sensitivity worsens or persists, it may be a result of one of the following:
One of the most common causes of tooth sensitivity after a filling is malocclusion (bite misalignment). A filling that’s too high can prevent your teeth from correctly fitting together when you bite or chew.
Incorrect bite alignment can put extra pressure on the affected tooth. This can cause pain and sensitivity. Sometimes, this causes the filling to crack.
Call your dentist if your bite feels off after the numbing wears off. It’s essential to have this fixed before the filling breaks.
An irritated nerve is a common cause of temporary tooth sensitivity after a dental filling. This happens when the nerve inside the filled tooth becomes inflamed due to the dental procedure.
The sensitivity will go away as the nerve heals. This can take a few days to a few weeks.
Pulpitis is inflammation of the pulp inside the tooth. It doesn’t usually occur with minor fillings, but you may experience pulpitis if:
There are two types of pulpitis:
It’s common to experience pain in the teeth surrounding the one that had a cavity filled. This phenomenon is called referred pain. It occurs when you feel pain in an area that isn’t the source.
Some people have allergic reactions to the dental filling material. If this happens, you might notice a rash or itching near the filled tooth.
Contact your dentist if you think you’re having an allergic reaction. They can remove the filling and replace it with a different material.
When dental fillings containing different metals, such as gold and amalgam, touch one another, they produce an electric current. This rare occurrence is called galvanic shock.
Just because it’s common to have sensitive teeth after a cavity filling doesn’t mean you have to suffer. There are many things you can do to reduce pain and discomfort, such as:
Tooth sensitivity after a filling is normal. Most people experience mild pain after having a cavity filled. It typically goes away in a few days.
Common causes of post-filling tooth sensitivity include irritated nerve endings and bite misalignment.
Contact your dentist if your pain is severe, persistent, or occurs with other symptoms such as a rash or fever. Also, call your dentist if you feel the filling is too high.
