Could an infected tooth cause a sinus infection?

Answer by  kf4vkp (295)

An immediate sinus infection caused by a tooth infection is not likely, however, a prolonged tooth infection can move into your sinus cavity and beyond. It is recommended that you seek a dentist's attention to your tooth as soon as possible. I would think that unless this was a reoccuring infection that the sinus infection is not connected.

Yes an infected tooth, especially if it is in the upper jaw, can lead to the infection spreading to the sinuses.

Yes it could cause a sinus infection, I had two infected teeth and had bad sinus headaches until I had both teeth pulled.

An infection would have to have spread down into an abscess and then up through the face. This makes the sinus infection likely only a coincidence.
