Location?: If the tooth involved and the infection occurs near the apex where the sinus is the proximity, the sinus infection may occurs. The wisdom tooth usually involved if it is affecting the ear such as tinnitus but not ear infection (ringing in the ear is more likely). Check with your dentist.

Unlikely: Bad teeth do not cause ear infections...however referred pain to the ears from infected teeth is very common...particularly lower molars.Sinusitis caused by infected teeth is not very common, but a real possibility. You need to have a comprehensive exam to determine which teeth, if any, might be involved. There is no way to tell without a professional exam and x-rays.

Sinus Infections-Yes: If you have teeth in the upper back jaw that are infected and left untreated, infection can permeate the floor of the sinus and cause pain, bone loss, and a host of complications. It is important to remember that unhealthy teeth are just one cause of sinus infections, and that there are several other causes. If you suspect your sinus infection is caused by a tooth, you should see your dentist to confirm this.

And worse!: Any infection can spread to other parts of the body. Untreated infections can lead to serious complications and should be treated by a health care professional.
