A sinus perforation can occur after the removal of an upper molar or premolar when a small opening forms between the mouth and the maxillary sinus. While uncommon, recognizing the symptoms early helps ensure it is managed properly.
With two convenient locations in Summerville, Deaton Dental Associates and Flowertown Dentistry provide comprehensive dental care for patients of all ages.

Symptoms of a Sinus Perforation After Tooth Extraction
A sinus perforation may create symptoms that involve both the extraction site and the sinus cavity. These symptoms are often most noticeable during the first few days of healing.
Symptoms to watch for include:
- Air or fluid passing between the mouth and nose
- A whistling sound when breathing or speaking
- A feeling of air moving through the extraction site
- Fluid leaking from the nose when drinking
- One-sided nasal congestion or sinus pressure
- Bad taste or drainage in the mouth
If a sinus perforation does not heal properly, it can increase the risk of sinus infection and may require additional treatment.
Risk Factors for Sinus Perforation After Tooth Extraction
The roots of the upper back teeth are often located very close to the maxillary sinus. In some patients, only a thin layer of bone separates the tooth from the sinus cavity. When one of these teeth is removed, an opening can occasionally develop between the extraction site and the sinus.
Factors that may increase the risk include:
- Roots of upper molars and premolars that sit close to the sinus
- Thin or weakened bone between the tooth and sinus
- Bone loss or infection before extraction
- More complex or surgical extractions
How a Sinus Perforation Is Treated
Treatment depends on the size of the opening, your symptoms, and how the area is healing. Many small perforations close on their own, while larger openings may require additional treatment to promote healing and reduce the risk of complications.
Management may involve:
- Monitoring: Small openings may heal naturally as a blood clot forms and the tissues close over the area. Follow-up visits help confirm that healing is progressing as expected.
- Medications: Antibiotics may be prescribed when indicated, along with decongestants or nasal sprays to reduce sinus pressure and support healing.
- Surgical repair: Larger openings may require a collagen plug, membrane, sutures, or repositioning of nearby gum tissue to close the communication between the mouth and sinus cavity. If a dental implant is planned, a bone graft may be recommended.
What To Do if You Think You Have a Sinus Perforation
If you notice symptoms that suggest a sinus perforation, contact your dentist as soon as possible for guidance. Early evaluation can help determine whether the opening is likely to heal on its own or if additional treatment may be needed.
Until you are evaluated, it is important to avoid activities that increase pressure within the sinus. Do not blow your nose, use straws, smoke, or perform forceful rinsing. If you need to sneeze or cough, do so with your mouth open to help reduce pressure on the healing area.
Prompt evaluation and appropriate care can help reduce the risk of complications and support a smoother recovery.
Clear Guidance Throughout Recovery
Most patients heal normally after a tooth extraction, but unexpected symptoms can sometimes occur during the recovery process. Understanding what is normal and when to contact your dentist can help prevent complications and support more predictable healing.
Drs. Rhett Deaton and Tiffany Deaton emphasize patient education and clear communication at every stage of care. They take time to explain healing expectations, answer questions, and help patients understand the appropriate next steps if concerns arise during recovery.

FAQ
How common is sinus perforation after tooth extraction?
A perforated sinus after tooth extraction is uncommon but can occur more often when removing upper molars because their roots are located close to the sinus floor.
How serious is a perforated sinus?
Most perforations are small and manageable, especially when identified early. Larger openings or untreated cases can lead to ongoing communication between the mouth and sinus or increase the risk of infection, which may require additional treatment.
Can a perforated sinus heal on its own?
Small perforations often heal on their own when a stable blood clot forms and the area is protected during healing.
