10 Surprising Reasons Your Nose Is Secretly Throwing a Polyp Party

9. The Dental Connection: When Tooth Troubles Stir Up Sinus Drama

Surprisingly, sometimes the "guest list" for your nasal polyp party might get an unexpected RSVP from your mouth! Odontogenic sinusitis occurs when an infection or inflammation from an upper tooth—often due to an abscess, complicated root canal, or dental implant issues—spreads directly into the adjacent maxillary sinus. This can trigger chronic sinus inflammation, creating fertile ground for nasal polyp development, usually on that one side. It’s a crucial, sometimes overlooked, connection. If you have persistent one-sided sinus symptoms and polyps, your doctor or dentist might investigate a dental source, as treating the tooth is key to ending that particular sinus fiesta.
