The Connection Between Sinus Infections and Tooth Pain
We’ve all been there. A strange ache in your upper teeth starts bothering you—yet everything seems fine with your teeth. But here’s something you may not have considered: sinus infections can actually cause tooth pain. Yes, that’s true. And it happens more often than you might think.
If you’ve ever had a sinus infection, you already know how uncomfortable it can be. Now imagine your sinuses putting pressure on your teeth. That’s when things get confusing. Many people end up going to the dentist thinking there’s a cavity or an abscess, only to find out it’s their sinuses causing the problem.
Let’s talk about why that happens, how you can tell the difference, and what you can do next.
How Your Sinuses and Teeth Are Connected?
Your body has several sinuses, but the ones you need to know about here are the maxillary sinuses. These are the ones closest to your upper back teeth. In fact, the roots of your upper molars are located just below these sinuses. That’s where the trouble begins.
When you get a sinus infection, these sinus cavities become swollen and filled with mucus. This swelling creates pressure in the surrounding areas—including your upper jaw and teeth. You might feel pain in multiple upper teeth on one side. Sometimes it even feels like a dull, throbbing ache.
Because the pain feels deep, it’s easy to assume that there’s something wrong with your tooth itself. But in reality, it’s the sinus inflammation pressing down on the nerves near your tooth roots.
What Does Sinus Tooth Pain Feel Like?
You might wonder, “How do I know it’s not a tooth problem?” It’s a valid question. Sinus-related tooth pain has some unique signs you can look out for.
Usually, the pain:
- Affects more than one tooth (especially the upper back teeth)
- Feels worse when you bend down or move your head
- Comes with other sinus symptoms like a stuffy nose, facial pressure, or headache
- Improves when your sinus symptoms go away
It’s also a dull and constant pain rather than a sharp one. And you’ll likely notice some pressure around your cheeks and forehead.
On the other hand, pain from a dental issue is more localised. It will usually affect only one tooth and might get worse when you chew or bite down.
When Should You See a Dentist?
Even if you suspect that your tooth pain is from a sinus infection, it’s still important to rule out dental issues. Sometimes, a dental infection can mimic sinus symptoms, and vice versa.
We always suggest getting a dental check-up if the pain doesn’t go away within a few days or gets worse. Your dentist can take an X-ray and figure out if the pain is truly sinus-related or if there’s an underlying dental issue.
It’s also possible for both problems to happen at the same time. So if your dentist doesn’t find anything wrong, you might want to visit your physician or an ENT specialist to check your sinuses.
Can a Sinus Infection Be Treated at Home?
In many cases, yes. If the infection is viral, it will usually go away on its own within 7–10 days. But that doesn’t mean you should suffer through the pain. There are a few things you can do to feel better.
Try using a saline nasal spray or rinse to clear out the mucus. Inhaling steam or using a warm compress can also relieve pressure. You can take over-the-counter decongestants or antihistamines if advised by your doctor.
Just keep in mind—if your symptoms last more than 10 days or start getting worse, it could be a bacterial infection. That’s when you may need antibiotics prescribed by a doctor.
What Happens If You Ignore It?
You might think, “It’s just a sinus infection. It’ll go away.” But ignoring the signs isn’t always the best idea.
If you leave it untreated, the infection can spread to nearby areas. You could develop chronic sinusitis, which lasts for weeks or even months. The pressure on your teeth can also get worse, making it hard to chew or even sleep.
Also, if the pain is actually coming from your tooth and not your sinuses, delaying treatment can make things worse. You might need a filling or even a root canal if a dental issue is left too long.
So don’t guess. Get it checked.
How to Prevent Sinus-Related Tooth Pain?
You can’t always stop a sinus infection from happening. But you can reduce the chances of it affecting your teeth.
Here’s what we recommend:
- Stay hydrated to thin out mucus
- Keep allergies under control, especially during seasonal changes
- Use a humidifier to avoid dry air in your home
- Practise good oral hygiene, even during a cold or flu
It’s also helpful to avoid sudden temperature changes—like stepping from an air-conditioned room into hot, humid air. This can trigger sinus trouble for some people.
