What’s the Connection Between Teeth and Sinuses?

Your mouth and nose are very close together! At the top of your upper jaw is a space called the maxillary sinus. This open space is just above your back teeth, especially your molars and premolars. Sometimes, the roots of these teeth even reach the edge of the sinus.

Why does this matter? If your teeth move, get infected, or are not in the right place, they can push on or bother the sinus above. That means problems with your teeth can sometimes feel like sinus pain—and sinus problems can feel like toothaches. It can be really confusing!

Why you should care: Knowing this helps you see that aches in your head or cheek might not be a cold or allergies—they could be because of your teeth!

Can Shifting Teeth Really Cause Sinus Issues?

The short answer? Yes—teeth that move out of place can sometimes cause or make sinus problems worse.

Let’s keep it simple. When teeth shift from their normal spots (maybe after losing a tooth, or when you’re growing), they can move closer to the sinus floor. If this happens, you might get:

• Odd pressure on the sinus
• Trouble with your bite
• Swelling or even infection if germs get in

Even just a bit of movement in your upper back teeth can put pressure on the maxillary sinus, causing pain, stuffiness, or headaches.

Problem: Many people don’t care when teeth move a little, thinking it’s no big deal.

Upset: But soon, they get headaches, pressure under the eyes, or a never-ending stuffy nose!

Fix: Dentists can see these things early and help you fix them—before you feel really bad.

How Jaw and Bite Problems Affect Your Sinuses

Do your teeth close together the right way? If not, you could have a bad bite (malocclusion). Here’s why this is a problem:

• When your jaws don’t line up, it puts stress on your jaw joints and cheek muscles.
• This can cause referred pain—meaning you feel the hurt in your sinus, not just your jaw.
• Some people with a crooked bite also have a smaller nose space to breathe from, making stuffy noses worse.

Example: Imagine a teenager with a deep bite and crowded upper teeth. They start having dull aches in the cheeks and headaches after chewing. Braces fixed their bite, and those aches went away!

Can Crowded or Impacted Teeth Bother Your Sinus?

Crowded teeth are teeth that don’t have enough space—like too many people trying to sit on one bench. Sometimes, teeth like your wisdom teeth don’t even come out all the way, so they’re called “impacted.”

• Impacted wisdom teeth can press up on the sinus floor, causing pain, swelling, or even small infections.
• Teeth squeezed together are harder to clean—leading to gum disease or abscesses, which can spread to the sinuses.

Clue: If you feel swelling in your upper jaw, pressure in your cheek or under your eye, and your teeth are crowded, don’t wait it out. Go see a dentist.

How Dental Treatments or Braces Impact Sinus Health

Did you ever have braces, clear aligners, or a palate expander? These help straighten teeth, but as your dentist moves teeth in your top jaw, the roots may move closer to the sinus.

Most people feel just some mild pressure or a stuffy nose for a few days. In rare cases, the roots might get too close to the sinus, which can cause problems that last longer.

Getting dental implants or having a tooth pulled in the back upper jaw? Sometimes, these treatments can make a tiny opening between your mouth and sinus, causing short-term sinus trouble.

If you’ve had dental work near your sinuses and your nose feels clogged or achy, call your dentist.

Can Dental Infections Cause Sinus Pain?

Yes! Infections that start in your teeth can move up into the sinus, causing tooth-related sinus infection. Here’s how:

• Cavities, gum disease, or a dental abscess (a pocket of pus) can break through bone, letting infection reach the maxillary sinus.
• You might feel pain above the hurt tooth, face pressure, swelling, and maybe even a low fever.

Here’s a simple table showing common sinus problems from dental infections:

If you see swelling, redness, or pus, especially after dental work, call your dentist right away.

Symptoms: How Do You Know if It’s Your Teeth or Your Sinus?

Let’s figure out the clues. Sinus issues and dental problems have a lot of the same signs, such as:

• Face pain or pressure (cheeks, under eyes, forehead)
• Headaches, especially at the sides of your head
• Tooth pain or sensitivity—worse with hot/cold drinks
• Stuffy nose or post-nasal drip
• Ear pain or a full feeling (ears and sinuses are close, too!)

But here’s what makes them different:

Mostly Sinus:

• Pain on both sides of cheeks or forehead
• Pain gets worse when you bend over
• Clogged nose with yellow/green mucus

Mostly Dental:

• Pain in just one tooth
• Pain gets worse with chewing or pressing on the gums
• Swollen gums or face, bad taste in mouth

Don’t know which you have? See a dentist or an ENT (ear, nose, and throat doctor)—you might need both!

How Dentists and Doctors Find the Problem

When you come in with face pain, a dentist will check:

• Every tooth for cavities, cracks, and if your bite is off
• Gums for redness, swelling, or pus
• Your bite and how your jaws move
• If you have jaw joint (TMJ) trouble

They might use dental X-rays or a CBCT scan (a 3D picture of your teeth, jaw, and sinus). It helps them see if tooth roots are close to the sinus, hidden infections, or even cysts.

If it’s more than a tooth problem,

• The dentist might send you to an ENT, or,
• Both doctors may work together to help you feel better.

How To Fix Dental-Related Sinus Problems

Prevention: Easy Ways to Keep Teeth and Sinuses Healthy

Good habits can help keep dental and sinus pains away:

• Brush twice a day and floss every night. This stops cavities and gum trouble.
• Visit your dentist every six months for a checkup and cleaning.
• If your or your child’s teeth are crowded or moving, ask about braces early.
• If you grind your teeth at night, ask about a custom night guard.
• Get treated quickly for any tooth pain, swelling, or infection—don’t wait!
• Use saline nose sprays if you get seasonal sinus trouble.

Frequently Asked Questions

Q: Can braces cause sinus pain?

A: Sometimes, yes, especially in the first few days after they’re tightened. This is because the roots of the top teeth can move closer to the sinus, but it doesn’t last long.

Q: Do all toothaches feel like sinus pain?

A: Not all, but pain in upper molars can sometimes feel like sinus pressure. If pain changes with head position or gets worse when chewing, see your dentist.

Q: Is it normal to have sinus problems after a tooth is pulled?

A: A little stuffiness can happen for a day or two, but if you notice a hole, bad taste, or pus, call your dentist—there could be a sinus opening.

Q: Can dental infections cause fever or swelling?

A: Yes. Dental infections that move to the sinus often cause swelling, redness, and sometimes fever. Get help quickly.

Main Takeaways: What Should You Remember?

• Teeth and sinuses are really close neighbors! Your upper back teeth and sinus floors almost touch.
