The sinus cavities are located behind the cheeks, eyebrows, and nose. These cavities are connected to the nose through a small opening called the ostium.
The sinuses are lined with a mucous membrane that secretes mucus; the mucus traps dust, bacteria, and other particles and prevents them from entering the lungs.
The sinuses also help to humidify the air that we breathe.
However, when the sinuses become blocked, mucus can build up and lead to infection. This can cause several symptoms, including pain, pressure, difficulty breathing, and post nasal drip.
Tooth Infections and Sinus Problems
One of the most common causes of sinus issues is a dental infection. The roots of the teeth extend into the sinus-cavity, and if these roots become infected, it can lead to sinus issues.
Root canal therapy is often used to treat this type of infection. Keep reading to learn more about the connection between bad teeth and sinus problems!
What Happens if a Tooth Infection Spreads to the Sinuses?
When a tooth infection spreads to the sinuses, it can cause a wide range of symptoms.
The most common symptom is sinus pressure. This is because the infected tooth is pressing against the delicate tissue in the sinus cavity. This pressure can lead to a great deal of discomfort and can make it difficult to breathe properly.
In addition to sinus pressure, a tooth infection can also cause sinusitis. Sinusitis is an inflammation of the sinus passages that can lead to pain, fever, and a feeling of pressure or fullness behind the eyes.
The infection can sometimes spread to the eyes, causing conjunctivitis or eye infections. A sinus infection can even spread to the brain if not treated, leading to meningitis or other serious complications.
