A sinus perforation occurs when an opening forms between your upper jaw and sinus cavity following a tooth extraction. This is most common with upper molars due to their close position to the maxillary sinuses and thin sinus floor.
In this blog, we explain what a sinus perforation is, how to recognize the signs, what treatment might involve, and why choosing the right oral surgeon makes all the difference in your recovery.

Sinus perforations are a known risk during upper tooth extractions, especially near the sinus cavity. Choosing an experienced oral surgeon who uses advanced imaging and precise techniques is the most effective way to prevent complications and support proper healing.
Services Offered at Foley & Le Oral Surgery
At Foley & Le Oral Surgery we specialize in tooth extractions, sinus lift procedures, sinus augmentation, bone grafting, and dental implant placement. Our team uses advanced CBCT imaging and minimally invasive techniques to reduce the risk of sinus perforations and support long-term healing.
How Does a Sinus Perforation Happen?
A sinus perforation may result from several anatomical or procedural factors:
- Thin sinus floor: Some people have very little bone separating their upper teeth roots from the sinus cavity.
- Large sinus cavities: A low sinus floor height (sinus pneumatization) makes it easier to perforate during extractions.
- Tooth trauma or infection: Deep tooth roots, infection around tooth roots that perforate the sinus floor, or prior surgeries can weaken the sinus membrane.
- Difficult extractions: Removing posterior teeth or upper back teeth can increase the risk of sinus membrane damage.
Symptoms of a Sinus Perforation After Tooth Extraction
Following an upper tooth extraction, keep an eye out for signs that may indicate a sinus perforation. Common symptoms include:
- Air passing between your mouth and nose: You may feel air escape through your nose when you talk, breathe, or swallow.
- Fluid leaking from the nose while drinking: This can happen if liquid enters the sinus cavity and drains through your nasal passages.
- Facial pressure or congestion: A feeling of fullness, tightness, or discomfort in your cheeks or under your eyes may signal sinus involvement.
- Whistling sound when breathing or speaking: This may occur if air flows through a small opening between your mouth and sinus.
- Unpleasant taste or bad breath: If bacteria or food particles enter the sinus cavity through the perforation, you may notice a persistent foul taste or bad breath, especially if an infection begins to develop.
- Swelling near the upper jaw or cheeks: Mild to moderate swelling may develop around the maxillary sinus area.
If you notice any of these signs, contact your oral surgeon promptly for an evaluation and treatment.
What Should You Do if You Suspect a Sinus Perforation?
If you think you may have a sinus perforation after an upper tooth extraction, it is important to protect the area while waiting to be evaluated. Follow these precautions:
- Do not blow your nose: Blowing your nose increases sinus pressure and can widen the opening between your mouth and sinus.
- Sneeze with your mouth open: This helps release pressure through your mouth instead of your nose, reducing the risk of disrupting healing tissue.
- Avoid using straws or creating suction in your mouth: Suction can dislodge the blood clot and delay healing at the extraction site.
- Only use nasal sprays if prescribed: Over-the-counter sprays may irritate the sinus lining and interfere with healing.
- Limit physical activity: Avoid heavy lifting or vigorous exercise, which can raise sinus pressure.
- Follow your post-op care instructions carefully: Take all prescribed medications as directed, including antibiotics or decongestants if given.
- Contact your oral surgeon as soon as possible: Prompt evaluation ensures the perforation is properly managed and helps prevent sinus infections or delayed healing
How Is a Sinus Perforation Treated?
Treatment depends on the severity and size of the perforated sinus.
Small Perforations
- Often heal naturally in two to three weeks
- A collagen dressing or bone graft may be placed over the tooth socket
- Antibiotics and nasal decongestants help prevent sinus infections
Moderate Perforations
- May require sutures to close the opening
- A non-resorbable membrane and bone graft may support tissue regeneration
- Frequent follow-up appointments are necessary to ensure the healing process is progressing
Large Perforations
- May require additional surgical intervention
- Bone or soft tissue grafting may be needed if the sinus floor is damaged
- A sinus augmentation or referral to an ENT may be necessary for complex cases involving sinus infections or bone fragments
| 💡Can You Still Get Dental Implants After a Sinus Perforation? Most patients are still good candidates for dental implants, even after a sinus perforation. If bone volume is reduced, your oral surgeon may recommend a sinus lift or bone graft before placing the implant. Careful planning and proper healing are key to long-term success. |
How to Reduce Your Risk of Sinus Perforation
While sinus perforations are not always avoidable, the best way to reduce your risk is by choosing a skilled oral surgeon who takes the right precautions.
At Foley & Le Oral Surgery, we use advanced CBCT imaging to map out your sinus anatomy before treatment. This allows us to plan precisely around the sinus cavity and tooth roots.
During surgery, we use gentle extraction techniques and, when needed, place bone graft material to preserve the sinus floor and support healthy healing.
Choosing an experienced oral surgeon is the most important step you can take to protect your sinus health during and after a tooth extraction.
