Little known facts and misconceptions:

The link between tooth and sinus infections

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 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.

When mouth bacteria meets your sinuses

Here’s how bacteria spreads from your mouth to your sinuses:

There are sinuses located behind your cheekbones and above your teeth.
Bacteria from a tooth infection or gum disease can reach these sinuses and cause secondary infections.
The sinus infection can lead to swelling, pain, and pressure in your cheeks and upper teeth.

When sinuses strike back

Sinus infections 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.
Sinus infections 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.

Guard your grin, so you can breathe easy

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.

Spot the signs and speak with your dentist

If you have upper tooth pain along with a stuffy or runny nose, the issues may be linked. Visit your dentist for dental issues and your doctor for sinus care. Treating both early helps you breathe easier and smile brighter!
