What is a sinus perforation during dental treatment?

A sinus perforation can occur during extractions or implant placement in the upper jaw. It happens when the thin wall of bone between the mouth and the sinus is breached. Small perforations often heal on their own with special care. Larger defects may require surgical closure. Symptoms include nasal fluid in the mouth or air leaking when you sneeze. Antibiotics and decongestants are often prescribed. Patients should sneeze with their mouth open and avoid blowing their nose. Smoking slows healing considerably. Follow-up X-rays confirm that the barrier has healed. With good care, most perforations heal without complications.
