What Is Oro-Antral Communication?
The term “oro-antral communication” refers to an opening that may occur after the extraction of upper molars, especially in cases where the tooth roots extend into the maxillary sinus (the air space in your upper jaw connected to your nose). When a tooth with deep roots is removed, a passage might form between your mouth and sinus, potentially causing discomfort and complications.
What Are the Signs and Symptoms?
Recognising an OAC early is key to effective treatment. Common symptoms include:
- A socket that doesn’t heal as expected
- Pain in the upper jaw, often extending to the eye and cheek
- Fluid or air escaping between the mouth and nose
- Sinusitis symptoms, such as a blocked nose or discharge
- Difficulty chewing due to tenderness in upper teeth
The classic complaint often includes throbbing pain on one side of the upper jaw, pressure extending to the eye, and a blocked or runny nose following the removal of an upper back tooth.
What Increases the Risk of OAC?
Certain factors may increase the likelihood of an OAC developing:
- Large sinuses or roots extending into the sinus
- Older age (40+)
- Difficult extractions or teeth with infection, cysts, or significant bone loss
- Conditions like periodontal disease or hypercementosis (excessive buildup on tooth roots)
- Dentists often take pre-extraction X-rays to assess the risk and identify potential complications.
- Treatment and Prevention
If an OAC is suspected or confirmed, the primary goal is to promote healing and prevent the connection from worsening. Here’s what you can do:
- Avoid actions that increase sinus pressure: Don’t blow your nose or hold in sneezes; instead, sneeze with your mouth open.
- Use prescribed medications: Decongestants and antibacterial mouthwashes like Savacol can help manage symptoms and prevent infection.
- Follow aftercare instructions carefully: This includes avoiding strenuous activity, maintaining oral hygiene, and attending follow-up appointments.
- In rare cases where healing doesn’t occur naturally, a surgical procedure may be needed. This often involves a gum flap being used to close the hole securely.
When to Seek Professional Help
If you experience persistent symptoms like prolonged pain, discharge, or difficulty healing after an upper molar extraction, consult your dentist straightaway. Timely intervention can prevent complications and ensure proper healing.
