Sinus Infections & Gum Disease

Gum disease and sinus infections may seem like completely different ailments, and at times they are. But what most people don't realize is that there may often be a connection between the two. Knowing what that connection is, and how gum disease may cause a sinus infection, may help you avoid possible problems.

Oral Hygiene

Having poor oral hygiene may cause bacteria to grow and begin the process of gum disease. Some of the symptoms of gum disease are bleeding gums, receding gums and extra sensitive gums.

Maxiallary Sinus

The oral cavity and upper teeth connect to the maxillary sinuses. If your upper teeth roots become diseased or infected, the bacteria from the infection may travel up the maxillary sinuses and cause a sinus infection.


Bacteria that build up due to a gum problem such as gum disease or a dental abscess, may actually cause a sinus infection by causing the abscess to go up into the sinus cavity.


It is a common complaint of people who have a sinus infection, to feel pain and pressure in their teeth. Usually it is the back teeth on top that will ache with a sinus infection, and is often called a sinus toothache.

Sinus Toothache Symptoms

Some of the symptoms you might experience if you have a sinus toothache, or a sinus infection caused by or affecting the teeth and gums, are swelling in the gums, tender cheekbones, swollen face, a headache, extreme tiredness and possibly some draining from your sinuses.
