Tooth Sensitivity After Filling – Is It Normal?


A filling is a treatment for a tooth damaged by decay. A filling restores the damaged tooth back to its normal function and shape while preventing further decay. It’s also the one of the most common procedures that takes place in the dental office. Fillings are safe and effective, but some people might experience temporary discomfort or tooth sensitivity after the procedure. In this article, we look at the reason why some tooth sensitivity after a filling can be considered normal and when to see your dentist about it. 

The procedure and what to expect after  

A filling is a dental procedure that involves a dentist cleaning away any decay from the tooth and then filling the space with a new material. After injecting a numbing agent around the tooth, the dentist will then clean out the decayed area of the tooth, usually with a dental drill. They will then fill the space with gold, silver amalgam, a composite, or porcelain. 

For several hours after having a filling, your face may still feel numb, tingly, itchy, or puffy. During this time you may have difficulty eating, swallowing, talking, or moving your face, this is completely normal and should not be a cause of concern. Once the numbing agent has worn off these feelings will go away, however you may notice a difference in tooth sensitivity even once the numbing agent has worn off.  

Sensitivity after filling – to be expected  

There are a few reasons why some discomfort or pain can be expected after dental fillings are done – and in the majority of cases it is likely to be a response to the repair work being carried out on your teeth. 

When you sit in your dentist’s chair for a filling, your dentist will poke and drill in your damaged tooth, often sparking sensitivity. If your tooth decay was located very close to the root of your tooth, your dentist will have accessed the area to clean it out, and this may temporarily exacerbate the sensitivity.  

When should sensitivity become be a concern? 

Tooth sensitivity after a filling is considered normal in the first two to three days after your filling. If your sensitivity persists after that, or the the pain is worsening, you should contact your dentist. Your dentist will then find the root of the sensitivity and be able to solve It with minimal hassle.
