Can rotting teeth cause sinus infections?

Rotting teeth, also known as dental caries or cavities, can cause a variety of health problems, including sinus infections. This is because the roots of the upper molars (back teeth) are very close to the maxillary sinuses, which are located on either side of the nose. When a tooth becomes infected, the bacteria can spread to the sinuses, causing inflammation and infection.

Sinus infections can cause a variety of symptoms, including:

* Facial pain and pressure

* Headache

* Nasal congestion

* Runny nose

* Fever

* Fatigue

* Loss of smell

* Bad breath

If you are experiencing any of these symptoms, it is important to see a doctor or dentist to determine if a sinus infection is the cause. Treatment for sinus infections typically involves antibiotics and decongestants. In some cases, surgery may be necessary to drain the sinuses.

To prevent rotting teeth and sinus infections, it is important to practice good oral hygiene, which includes:

* Brushing your teeth at least twice a day

* Flossing your teeth once a day

* Avoiding sugary foods and drinks

* Seeing your dentist regularly for checkups and cleanings

If you have any questions about how to prevent rotting teeth or sinus infections, talk to your doctor or dentist.
