Is it Normal to Have Tooth Sensitivity After a Dental Filling?

Posted on: September 16, 2018

Many who receive a dental filling for the first time become concerned and wonder whether or not it is normal to have tooth sensitivity after the dental filling. Although it is a simple question, the answer is a bit more complicated. However, this article covers everything you need to know about tooth sensitivity after a dental filling.

Is tooth sensitivity normal after a dental filling?

In most instances, tooth sensitivity after a dental filling is not a call for major concern. With the right treatment at home and some patience, the sensitivity and pain should go away after a few days. With that said, any tooth sensitivity after a dental filling that becomes extremely severe or lasts for an extended amount of time should be treated by a dentist.

What causes tooth sensitivity after a dental filling?

It is completely normal to feel some tooth sensitivity after a dental filling, although the level of sensitivity should be manageable. In order to properly assess the severity of the tooth sensitivity, it is important to know the exact causes.

Here are the most common causes of tooth sensitivity after a dental filling:

  • Inflamed pulp
  • Change in bite pattern
  • Pain in the surrounding area
  • Allergic reaction (in rare cases)

After a dental filling, there are a lot of new things going on within the affected area that can cause teeth to become sensitive. In most instances – such as when the pulp of a tooth becomes inflamed, there is a change in bite pattern or there is pain in the surrounding areas as a result of the filling – it is not a call for concern. However, contact your dentist immediately if you feel as if you are having an allergic reaction to the substance used during the filling.

How long does the sensitivity last?

In general, the sensitivity should start to go away after a week or two at most. In many instances, the sensitivity only lasts for several days.

In the event that tooth sensitivity after a dental filling lasts for more than several weeks, be sure to contact your dentist to find out the cause of the sensitivity. In rare instances, there may have been an error during the filling process that can be easily fixed. With that said, it is important to be patient, and the tooth sensitivity should go away through the utilization of proper oral hygiene.

Can you relieve the sensitivity?

The best way to relieve tooth sensitivity after a dental filling is to avoid things that irritate the tooth. The most common cause of irritation to a sensitive tooth is hot and cold food and drink. Also, practicing good oral hygiene is a great way to relieve tooth sensitivity. Be sure to brush frequently and floss after each meal. It is important to also brush the affected area softly to avoid any irritation. Lastly, taking painkillers can reduce the sensitivity in a tooth after a dental filling, although it should not be used as the main method of managing the sensitivity.
