Why Are My Teeth Sensitive After a Filling?

Having a cavity filled is meant to relieve discomfort and protect your tooth, so sensitivity afterwards is, understandably, a little frustrating. Fortunately, mild sensitivity after a dental filling is common and often improves as your tooth settles following the treatment. You may notice some discomfort when eating, drinking, or biting down. How long this sensitivity lasts will depend on the tooth and the depth of the original cavity.

Common Reasons for Tooth Sensitivity After a Filling

A tooth may become temporarily sensitive after a filling because the dental pulp, which is the soft inner tissue containing nerves, can become irritated during removal of the decay and the placement of the filling. Deeper cavities may cause more noticeable sensitivity because the treatment is performed closer to the pulp. You may also experience sensitivity to hot or cold temperatures, sugary foods, acidic foods, or pressure from biting.

Another possibility is that the filling is slightly too high. If the restored tooth makes contact before your other teeth when you bite down, the additional pressure can lead to discomfort when chewing. This may require an adjustment from your dentist to fix.

Less commonly, persistent or severe sensitivity can indicate inflammation or other complications with your tooth. If tooth sensitivity continues, please contact your dentist for further assessment.

How Long Does Sensitivity Last After a Filling?

Mild tooth sensitivity generally improves after anywhere from a few days to a couple of weeks. The recovery period can vary, particularly when a filling is deep and closer to the tooth's nerve. What matters most is whether the discomfort is gradually improving. Sensitivity that becomes stronger, persists or is accompanied by other symptoms can indicate further problems and should be evaluated by a dentist.

How to Reduce Sensitivity After a Filling

Tooth sensitivity after a filling can make regular activities such as eating or brushing unpleasant, so most people look for ways to reduce their level of sensitivity. While you’re waiting for your tooth to settle, these simple changes can make eating and drinking more comfortable:

• use a toothpaste made for sensitive teeth

• temporarily avoid very hot or cold foods and drinks

• chew on the opposite side if biting on the treated tooth is uncomfortable

• continue brushing gently and maintaining good oral hygiene

• follow any post-treatment instructions provided by your dentist

These approaches may help manage temporary discomfort so you can eat and drink normally while your tooth recovers.

When Should You See a Dentist?

You should contact your dentist if sensitivity is getting worse instead of better, lasts longer than expected, or causes pain when you bite. Severe tooth pain also warrants professional attention. If discomfort occurs alongside symptoms such as swelling or fever, contact a dentist immediately for an assessment.
