Few things are more frustrating than facial pain—especially when you’re not sure what’s causing it. If you’re feeling pressure or aching around your upper back teeth, you might assume it’s a dental issue.
But did you know that sinus infections often mimic the symptoms of a toothache? Understanding the difference between the two can help you decide whether to call your dentist or wait it out with home care.
Here’s how to tell the difference between a true toothache and sinus pressure.
Why Sinus Problems Can Feel Like Toothaches
Your maxillary sinuses are located just above your upper molars, separated only by a thin wall of bone. When these sinuses become inflamed due to allergies, a cold, or a sinus infection, the swelling and pressure can press down on the roots of your upper teeth. As a result, you may feel a dull, aching pain that seems to come from the teeth, even though the source is actually in your sinuses.
Symptoms of a Sinus-Related Toothache
If your tooth pain is caused by sinus pressure, it will typically:
- Be felt in several upper back teeth, not just one
- Worsen when you bend over or move your head quickly
- Be accompanied by sinus congestion, facial tenderness, or post-nasal drip
- Improve with decongestants, nasal sprays, or other sinus treatments
In most cases, sinus-related tooth pain is dull and diffuse rather than sharp and localized.
Signs of a True Toothache
On the other hand, a genuine toothache caused by decay, infection, or trauma often feels different. You may notice:
- Pain that’s sharp, stabbing, or throbbing
- Sensitivity to hot, cold, or sweet foods
- Swelling or redness around the affected tooth or gums
- Pain that doesn’t improve with sinus treatments
If your discomfort is isolated to a single tooth and persists regardless of changes in sinus pressure, it’s time to contact your dentist.
When to See a Dentist
It’s not always easy to tell the difference between a sinus infection and a dental issue, so it’s best to err on the side of caution. If the pain lasts longer than a few days, worsens, or is accompanied by swelling or fever, you should reach out to a provider of emergency dentistry in Herndon. A dentist can perform an exam, take x-rays if needed, and determine whether the pain is coming from your tooth or your sinuses.
In some cases, your dentist may refer you to a primary care doctor or ENT specialist if they suspect the issue is sinus-related.
If your tooth pain doesn’t improve—or gets worse—it’s time to take action and get the relief you need.
