My Teeth Are Sensitive After a Filling

What Causes Tooth Sensitivity After a Dental Filling?

It is not uncommon to develop some sensitivity after a tooth has been filled. In some cases, sensitivity can even grow into pain. If you experience sensitivity in a tooth that has had a dental filling, this is not always cause for concern.

Some common reasons for tooth sensitivity after getting fillings include:

• The filling is very large, allowing heat to be conducted from the tooth nerve causing irritation
• A filling is placed very rapidly, stressing surrounding areas, and aggravating tissue in the tooth.
• The filling is high and our periodontal ligaments may get struck by inflammation and tenderness as a consequence

The most common side effect of fillings is aggravated tooth nerves or short term teeth sensitivity. Sometimes treating tooth decay involves the inadvertent aggravation of the tooth nerve, similar to how you may feel after you have undergone a surgical procedure. Tissues can become inflamed, and nerves can become irritated, which you may feel more acutely after the anesthetic has worn off.

Although a dental filling procedure can result in nerves becoming irritated, most often, eventually this overstimulation should die down. It is not uncommon to experience some post-procedures sensitivity. However, if your tooth sensitivity does not fade away in time, or grows worse, contact your dentist right away.
