Sore Smiles: Does Sinusitis Cause Toothaches?

January 6, 2025

If you have a persistent or severe toothache, it’s natural to wonder whether it warrants an emergency visit to your dentist. After all, there are many potential causes behind your throbbing, and some are more urgent than others.

For example, it could be caused by an injured or decayed tooth that needs to be treated as soon as possible. However, there’s a chance you might be experiencing sinus aches that should be addressed by an appropriate physician. Continue reading to learn more about the difference between dental discomfort and sinusitis to know who to call for help!

What is Sinusitis?

Your sinuses are air-filled passageways near your facial bones and teeth that typically moisten, warm, and filter the air you breathe through your nostrils. Unfortunately, if the lining of these cavities becomes inflamed or swollen, you can develop an infection that causes a backup of mucus and fluid. This built-up pressure can cause a stuffy nose, head and tooth aches, and a stiff jaw.

What Does Sinus Pain Feel Like?

It can be challenging to tell whether a sinus problem or oral issue is behind your discomfort, but a few signs can help you differentiate between the two. For instance, the throbbing caused by this type of infection tends to be a duller ache that impacts several teeth. Also, jumping or bending might make it hurt worse because of the pressure shifts as you move. The upper molars are most likely to be affected because they’re physically closer to surrounding cavities than your other pearly whites.

You might also present with additional symptoms that point to sinusitis, such as:

  • Fever.
  • General fatigue.
  • A sore throat.
  • Bad breath.
  • Facial tenderness.
  • Ear pain, ringing, or fullness.
  • Thick, discolored mucus.

How Are Toothaches Different from Sinusitis?

There are many types of toothaches and some that linger can easily be mistaken for a sinus issue. You might know you’re dealing with an oral issue if:

  • The discomfort is intense and focused on a single area.
  • You have a tingling or sharp sensation when biting into anything too hot or cold.
  • You notice discoloration in the sore tooth or surrounding gum tissues.
  • The ache is persistently worsening.
  • The feeling doesn’t change based on whether you’re standing, sitting, or lying down.
  • Swollen gums.
  • Difficulty biting or chewing.
  • Oozing or bleeding in your teeth or gums.
  • Trouble opening your mouth fully.

If you’re still unsure of the culprit behind your throbbing tooth, it’s best to err on the side of caution and contact your dentist. They can address many types of issues impacting your oral health and will refer you to a doctor if needed.
