Did you know that some toothaches actually start in your sinuses? Studies show more than 40% of sinus infections actually start in the teeth.
Our mouths and our sinuses are connected in many ways. On the positive side, our senses of taste and smell can complement each other, making a favorite meal even more delicious. But your mouth and your sinuses can also be linked by bacteria and infection:
A tooth infection, also called a dental abscess, happens when harmful bacteria reach the nerve of a tooth.
A sinus infection (sinusitis) is when bacteria is trapped in your sinuses, causing pain and inflammation.
How can bacteria from your mouth cause a stuffy nose? Why can a sinus problem cause a toothache? Let’s find out.
Here’s how bacteria spreads from your mouth to your sinuses:
There are sinuses located behind your cheekbones and above your teeth. The roots of your upper back teeth sit just below the maxillary sinuses, thin layers of bone are all that separate them. That’s why infections or inflammation in one area can easily affect the other.
Bacteria from a tooth infection or gum disease can reach these sinuses and cause infection.
The sinus infection will lead to swelling, pain, and pressure in your cheeks and upper teeth.
This tooth-sinus connection goes both ways, which mean that sinusitis can also cause dental issues:
Inflamed sinus tissue can push on the roots of your teeth and cause aching pain that may feel like a cavity.
Sinusitis can cause mucus to drain down the back of your throat and create bad breath.
Sinus problems, congestion, and swelling can make it more difficult to chew and swallow.
Since sinus infections and dental problems can cause similar symptoms, it’s not always easy to tell where the pain is coming from. Here are a few clues that can help you spot the difference.
Sinus-related tooth pain:
Affects several upper teeth at once
Feels dull or pressure-like rather than sharp
Worsens when bending over
Tooth-related pain:
Usually isolated to one tooth
Sharp, throbbing, or worsens with hot/cold
May come with gum swelling or sensitivity
You can protect your teeth, gums, and sinuses with regular oral health care:
Brush twice and floss once daily.
Consider using an antimicrobial mouthwash to reduce oral bacteria.
Drink plenty of water to thin mucus and keep your mouth clean.
Avoid smoking and other pollutants that may irritate your nasal passages.
If you have upper tooth pain along with a stuffy or runny nose, the issues may be linked.
If your symptoms last more than 10 days, worsen after improving, or you notice swelling in your face or jaw, it’s time to see a professional.
Your dentist can rule out a dental abscess, and your physician can treat chronic or recurrent sinus infections.
Treating both early helps you breathe easier and smile brighter!
