Why Tooth Hurts After Filling?

Short-term tooth sensitivity after a filling usually occurs because the filling procedure has aggravated or caused inflammation in the nerve inside the tooth. Usually, the tooth's outer layers — the enamel and cementum — protect the nerve from exposure.

How long will tooth hurt after filling?

Sensitivity from a tooth filling should go away within two to four weeks. If the sensitivity doesn't seem to be getting any better during that time, or it lasts for longer than four weeks, contact your dentist.

Is it normal to have tooth pain after a filling?

Tooth sensitivity following placement of a filling is fairly common. A tooth may be sensitive to pressure, air, sweet foods, or temperature. Usually, the sensitivity resolves on its own within a few weeks. During this time, avoid those things that are causing the sensitivity.
