Reasons Your Tooth Still Hurts after Getting a Filling

Do you still experience a toothache after getting a filling? This blog is for you if that’s the case. Getting a filling can treat several dental issues. But it’s not uncommon to experience tooth sensitivity following the procedure. 

Tooth sensitivity is discomfort that often occurs when you consume hot, cold, or sweet foods. It can take any form, from throbbing pain to gradual sensation. If you experience such a condition, rest assured as it’s a common side-effect of dental work, and your dentist can treat it. This blog will address the potential reason why you may experience a toothache after getting a dental filling. By the end of this blog, you’ll know the possible causes which can help you take appropriate measures to treat the issue. Let’s get started!

Why your tooth still hurts after getting a tooth filling

It’s common to experience sensitivity right after the dental procedure. Talk to your dentist if the discomfort persists for weeks because it can signify an underlying oral health problem. That being said, here are some possible causes of this issue.

Improper installation

Improper installation of filling can cause toothache. If it’s not placed correctly or disrupts the bite, your tooth may hurt when you eat anything. This can also cause cracks on your filling, making them fall eventually. You may let your dentist see whether your fillings are installed correctly if you feel persistent pain after the procedure.

It can be due to an infection

Persistent pain or sensitivity signifies that there’s something wrong. If your tooth hurts for weeks or months after the procedure, get your oral health checked by a professional. It might be due to oral infection development after your dental work. Get it treated right away to prevent further complications.

Exposed nerves

You may have exposed nerves or other sensitive tissues with you experiencing a persistent toothache or tooth sensitivity after your dental work. That can be due to improper installation or cracked fillings, triggering discomfort when consuming high- or low-temperature foods.

Allergic reactions

Some people experience persistent tooth sensitivity when they’re allergic to the material. It’s better to check your immune responses to a particular material before choosing it.

What can I do to help relieve tooth sensitivity?

Follow these tips to help manage tooth sensitivity:

  • Brush and floss regularly
  • Perform mouth rinses with lukewarm saltwater
  • Use a toothpaste for sensitive teeth
  • Visit your dentist if the discomfort persists for longer


Experiencing tooth sensitivity after dental work is common and can be due to various reasons. You might be allergic to the material. Some people experience it because of an underlying infection or exposed nerves. Others face discomfort due to improper installation or cracked fillings. But if the discomfort persists for weeks or months, it can signify an underlying oral health problem. Visit your dentist right away when pain or sensitivity doesn’t resolve within a few weeks. If left untreated, it may worsen your condition.
