Is It Normal To Have Tooth Sensitivity After Filling?

There is a multitude of reasons why you may need dental filling. However, the first signal that you may need a filling is if you experience sensitivity in the mouth. 

A dental filling is a recommended treatment choice if the tooth sensitivity after filling persists, which would be needed to fill a cavity (a tiny hole or opening in the tooth root) or treat decay in the mouth. Dental filling treatment is safe and is designed to fill a hole in the tooth root for the long term. 

One of the key questions patients ask is: is it normal to have tooth sensitivity after filling? With any treatment, minor sensitivity should be expected during and after treatment. Although, you shouldn’t expect the sensitivity to be long-term. If that is the case, you may need to consult the dentist for further support.

Let’s learn more about dental fillings and sensitivity.

When Would I Need A Dental Filling?

If you’re experiencing sensitivity, particularly in the back molars of your teeth, then it is a sign that you need a dental filling. You’ll naturally feel sensitivity in hot and cold temperatures. Eating hot and cold foods is also an indicator that you need a dental filling. If this happens, when eating and chewing, you’re likely to experience a throbbing pain, which is another indication.

Should I Expect Sensitivity After Dental Filling Treatment?

Tooth sensitivity after filling treatment should be expected. Although, the sensitivity would mainly occur during the procedure and just for a few days after

If the dentist does not clean the diseased region, the sensitivity will worsen without filling treatment. The infection could potentially spread to the tooth root, exposing and harming the blood vessels. Therefore, the dentist would need to drill into the affected tooth to clean out any decay that has occurred. Before the dentist does this, you will be administered a numbing agent so you don’t feel a lot of pain during the treatment.

Then, the hole is subsequently filled with either composite or amalgam filling material. The sensitivity that occurs after the filling may last for a few hours, affecting overall mouth function like speaking and chewing.

How Can I Manage Any Sensitivity After Dental Filling?

For the first two to three days after treatment, you’re likely to be in pain. If the sensation persists for more than three days, you should see a dentist.

Here are some suggestions for reducing sensitivity after filling:

  • Take an anti-inflammatory medicine from over-the-counter drug stores, such as ibuprofen and acetaminophen
  • Stay away from hot and cold beverages and drinks since these can aggravate sensitivity.
  • When brushing your teeth around the filled region, be gentle. You want to avoid disturbing or dislodging the filling
  • Drink more water instead of sugary and acidic drinks as this can build harmful bacteria
  • Softer foods such as potatoes, soup, and green vegetables should be added to a softer diet

My Dental Filling Has Dislodged. What Do I Do?

The tooth filling may become dislodged because of a dental injury. A dental injury can mean a physical collision or bite down on something hard (which is not recommended if you have a dental filling fitted). It is essential that you see a dentist as soon as possible if this occurs. 

Bacteria and food debris will soon infect the tooth, which will then spread to the tooth root and vessels if the filling is dislodged. Bring the dislodged filling with you in a moist container as the dentist may look to relodge the filling or fit a new one altogether. Even if the filling has dislodged, brush and floss your teeth to keep the tooth as healthy as possible. 

When you arrive at the dentist, explain to the dentist how the filling became dislodged and let them know if you’re experiencing any tooth sensitivity after filling.
