The sinuses, teeth, and gums all share related nerves that can transmit pain signals.
Inflammation due to sinus infection or dental infection can press on these nerves, leading to pain. Therefore, a person interprets these signals as dental pain.
Can a dental disease cause a sinus infection?
A dental infection causes a sinus infection.
A data review from 2012 estimated 40% of chronic maxillary sinus infections was due to dental infections.
Some studies considered this amount about 10-15%, but advances in imaging and CT scans have revealed dental infections as a common underlying cause.
A person with this infection type has maxillary sinus infection symptoms. In addition, they may have the following risk factors relating to their teeth:
- History of the jaw or dental pain
- History of or dental infection
- History of endodontic, oral, or periodontal surgery, tooth extractions

Abscess tooth not responding to antibiotics
If oral antibiotics do not fix the abscess, you’ll need to return to the dentist. In some cases, you’ll need to visit the dentist for treatment of the infected tooth. This is when IV antibiotics are needed.
This is the case when you first notice the abscess. An abscess might not show severe, but it is a severe medical condition. You can reduce the pain with OTC pain relief, but you need to see a dentist for urgent attention.
Alternative Treatment Options
Someone with pus-filled nasal discharge also benefits from antibiotics. Treatment for sinusitis is amoxicillin. If a person is allergic to amoxicillin, a doctor orders clarithromycin.
Surgery can increase sinus passages to reduce the possibility of infection and irritation occurring.
