Concerns About Wisdom Teeth: Unusual Nasal Leakage After Rinsing - Dentistry

Wisdom tooth issues


Hello: I raised a question about my wisdom teeth yesterday but haven't received your response yet.
I have discovered another issue: when I have water in my mouth or rinse, water flows from my nostrils.
Even after I spit out the water in my mouth, some water continues to come down after a while.
This situation is really frightening me.
Is there a problem related to my tooth extraction? What should I do in this case? Will it recover on its own, or do I need to seek additional medical attention?

Generally, fluid from the oral cavity may flow out of the nostrils, which can occur during the tooth extraction process (especially for the maxillary molars) due to the anatomical position of the tooth roots being very close to the maxillary sinus.
This can result in an oral-antral fistula, leading to a communication between the oral cavity and the nasal cavity.
If the size of this communication is small (less than 2mm), as long as the extraction site remains clean, it will typically heal on its own.
However, if the communication is larger, a surgical flap procedure may be necessary to close the fistula, and after healing, the communication between the oral cavity and nasal cavity will no longer be present.

More Info


It sounds like you are experiencing a concerning issue following your wisdom tooth extraction, specifically the unusual nasal leakage when rinsing your mouth. This symptom can indeed be alarming, and it is important to understand the potential causes and appropriate steps to take.

Firstly, the phenomenon you are describing—where water from your mouth flows out of your nose—suggests a possible connection between your oral cavity and nasal cavity. This can occur if there is a communication between the two, often referred to as an oroantral fistula. This condition can arise after the extraction of upper wisdom teeth, particularly if the tooth roots are close to the maxillary sinus, which is located above the upper jaw. If the extraction site is not healing properly, or if there was significant manipulation during the procedure, it could lead to this abnormal connection.

The presence of an oroantral fistula can result in several symptoms, including nasal leakage of fluids, difficulty in swallowing, and even recurrent sinus infections. It is crucial to address this issue promptly, as it may not resolve on its own and could lead to further complications if left untreated.

Here are some steps you should consider taking:
1. Avoid Forceful Actions: Refrain from forcefully blowing your nose or engaging in activities that could increase pressure in your nasal passages, as this may exacerbate the leakage.

2. Contact Your Dentist or Oral Surgeon: It is essential to reach out to the dental professional who performed your extraction. They can evaluate your condition, possibly through a clinical examination and imaging studies, to determine if an oroantral fistula is present.

3. Follow-Up Care: If a fistula is confirmed, your dentist may recommend surgical intervention to close the opening. This could involve suturing the tissue to promote healing and prevent further complications.

4. Monitor Symptoms: Keep an eye on any additional symptoms, such as pain, swelling, or signs of infection (like fever or increased drainage). If you experience any of these, seek medical attention promptly.

5. Maintain Oral Hygiene: While it is important to keep the extraction site clean, be gentle when rinsing your mouth. Use a saline solution or an antibacterial mouthwash as recommended by your dentist to help prevent infection.

6. Consider a Specialist: If your symptoms persist or worsen, you may be referred to an oral and maxillofacial surgeon for further evaluation and treatment.

In terms of recovery, if an oroantral fistula is treated appropriately, most patients can expect to heal well. However, the timeline for recovery can vary based on individual circumstances, including the size of the fistula and the overall health of the patient.

In conclusion, while the nasal leakage you are experiencing is concerning, it is essential to consult with your dentist or oral surgeon as soon as possible. They will provide the best guidance tailored to your specific situation and ensure that any complications are addressed promptly. Remember, timely intervention is key to a smooth recovery and preventing further issues.
