Nasal discharge of yellow fluid?

Good evening, Dr.
Lin: On August 10 (Tuesday), I underwent the first root canal treatment on the second tooth from the upper right, counting from the wisdom tooth, with anesthesia administered.
Post-operative recovery of the tooth was satisfactory.
On August 17 (Tuesday), I had the second root canal treatment on the same tooth, also with anesthesia.
However, the discomfort from the anesthesia was more severe than the last time.
I felt tightness in my cheekbone when opening my mouth, and pressing on my cheek caused pain.
On August 18 (Wednesday), I still experienced pain when pressing on the cheekbone of my right cheek, and felt tightness when opening my mouth, accompanied by right-sided headaches.
On August 19 (Thursday), I noticed a sudden, involuntary discharge of yellow fluid (not nasal mucus) from my right nasal cavity when bending down, which was odorless, occurring once at 2 PM and again at 5 PM.
I am unsure of the cause of these symptoms and kindly request your assistance in clarifying them.
Thank you.

Hello: If sinusitis is suspected, it is recommended to perform a CT scan for confirmation.
Usually, tooth extraction, dental implants, or apicoectomy procedures are more likely to complicate sinusitis.
Based on your description, since only root canal treatment has been performed, it is possible that the prolonged mouth opening has led to the sensation of "tightness when opening the mouth, accompanied by right-sided headache." The presence of fluid in the nasal cavity should be confirmed by an otolaryngologist using an endoscope.
Sincerely, Lin Chia-Yung, Department of Dentistry, Taichung Hospital, Ministry of Health and Welfare.

More Info

After undergoing dental procedures, particularly those involving the upper teeth, patients may experience various symptoms, including yellow nasal discharge. This phenomenon can be concerning and may lead to questions about its causes and implications.

In your case, the yellow nasal discharge following root canal treatments could be attributed to several factors. First, it is essential to understand the anatomical relationship between the upper teeth and the nasal cavity. The roots of the upper molars and premolars are often located close to the maxillary sinus (antrum), which is a cavity within the skull that connects to the nasal passages. During dental procedures, especially those involving extraction or significant manipulation of the upper teeth, there is a risk of inadvertently affecting the sinus membrane. This can lead to a condition known as a sinus perforation, where the sinus cavity becomes open to the oral cavity, potentially allowing for the passage of fluids and air between the two spaces.

The yellow color of the nasal discharge you are experiencing may indicate the presence of mucus that could be a result of inflammation or infection. While it is not uncommon to have some degree of post-operative swelling and irritation, the presence of yellow discharge could suggest a possible sinus infection (sinusitis) or inflammation of the sinus lining. This is particularly relevant if you are experiencing additional symptoms such as facial pain, pressure, or headaches, which you mentioned in your description.

Another possibility is that the yellow discharge could be related to the healing process itself. After dental procedures, especially those involving bone grafts or sinus lifts, the body produces various fluids as part of the healing response. These fluids can sometimes drain into the nasal cavity, leading to unusual discharge. However, if the discharge is persistent, has a foul odor, or is accompanied by other symptoms such as fever or increased pain, it is crucial to seek further evaluation.

Given your symptoms, it is advisable to consult with an ear, nose, and throat (ENT) specialist. They can perform a thorough examination, possibly including imaging studies like a CT scan, to assess the condition of your sinuses and determine if there is any perforation or infection present. Additionally, they can provide appropriate treatment options, which may include decongestants, nasal saline rinses, or antibiotics if an infection is confirmed.

In summary, while yellow nasal discharge after dental procedures can be concerning, it is essential to consider the context of your symptoms and the potential anatomical connections involved. Prompt evaluation by a healthcare professional can help clarify the situation and ensure that any necessary treatment is initiated. Remember to maintain good oral hygiene and follow any post-operative care instructions provided by your dentist to minimize complications.
