Lymph Nodes: Concerns After Wisdom Tooth Extraction - Otolaryngology

Submandibular lymph nodes


Hello, Doctor.
About 2.3 weeks ago, I noticed a lymph node approximately 0.5-1 cm in size in my right lower jaw (it is more prominent when I clench my jaw).
I was a bit worried and kept touching it (I have a tendency to worry about health issues).
Then, two weeks ago, after I had my right lower wisdom tooth extracted, I noticed a new lymph node appeared next to the existing one, about the same size.
As I became increasingly anxious and kept pressing on it, it seems to have started causing some pain.
I visited an ENT clinic and a dermatology clinic, and they both suggested that it might be related to the acne on my chin (which is somewhat severe).
They also mentioned that it is likely not a significant concern.
Currently, the swelling from the wisdom tooth extraction has subsided, leaving only a little soreness, and I have just started treatment for the acne.
My body temperature and other parts of my body are normal.
Doctor, could pressing on the lymph nodes cause inflammation and pain?

Hello: Repeated pressure on the lymph nodes may also lead to inflammation and pain.
If you have already seen a doctor, you can have regular follow-up visits.
If there is no significant enlargement, it is likely a benign condition.
Wishing you safety and health.
Sincerely, Dr.

More Info


After wisdom tooth extraction, it is not uncommon to experience some swelling and tenderness in the surrounding areas, including lymph nodes. Lymph nodes are part of the immune system and can become reactive in response to infections, inflammation, or even physical irritation. In your case, the presence of a lymph node that has become more prominent and possibly painful after your wisdom tooth extraction could be due to several factors.

Firstly, the extraction of a wisdom tooth, especially if it was impacted or required surgical intervention, can lead to localized inflammation. This inflammation can cause nearby lymph nodes to swell as they work to filter out any potential pathogens and respond to the healing process. The fact that you have noticed a new lymph node appearing near the site of your extraction is not unusual, especially if there was some degree of trauma or infection associated with the procedure.

Regarding your concern about repeatedly pressing on the lymph nodes, it is indeed possible that constant manipulation can lead to irritation and even mild inflammation. Lymph nodes are sensitive structures, and excessive pressure can cause discomfort or pain. It is advisable to avoid poking or pressing on them, as this can exacerbate any existing inflammation and lead to further discomfort.

You mentioned that you have been diagnosed with acne in the area, which can also contribute to lymph node swelling. Acne can lead to localized infections, and the body’s immune response to these infections can cause nearby lymph nodes to enlarge. The fact that you are undergoing treatment for your acne is a positive step, as managing the skin condition may help reduce the associated lymph node swelling over time.

In terms of your overall health, the absence of fever and the normal condition of other body parts are reassuring signs. It indicates that there may not be a systemic infection at play. However, if the lymph nodes continue to swell, become increasingly painful, or if you develop other symptoms such as fever or significant fatigue, it would be prudent to follow up with your healthcare provider for further evaluation.

In summary, the swelling of lymph nodes after wisdom tooth extraction can be a normal response to the surgical trauma and inflammation. Constantly pressing on them can lead to irritation and pain. It is essential to monitor the situation and avoid unnecessary manipulation of the lymph nodes. If you have any concerns about the swelling or if symptoms persist, do not hesitate to seek further medical advice. Your healthcare provider can offer guidance tailored to your specific situation and may recommend imaging studies or further examinations if necessary.
