Swollen submandibular lymph nodes can come from many sources. Infections in the head, neck, sinuses, ears, eyes, scalp, and throat are common causes. Bacterial and viral infections are the main reasons, with dental problems being a big one. For example, an abscessed or impacted tooth can cause swelling.
The table below lists common causes of swollen submandibular lymph nodes:
| Cause | Description |

FAQ
What are submandibular lymph nodes, and what is their function?
Submandibular lymph nodes are small, bean-shaped structures located under the jawline that act as immune system filters. They trap and destroy bacteria and viruses originating from the teeth, tongue, and throat.
What causes submandibular lymph node swelling?
The most common causes are local infections such as tooth abscesses, strep throat, or the common cold. They may also react to viral illnesses like mononucleosis or skin infections on the face and neck.
How can I tell if my swollen submandibular lymph nodes are a cause for concern?
Nodes that are hard, fixed in place, or painless and continue to grow after two weeks are more concerning. Seek medical advice if swelling is accompanied by night sweats, unexplained weight loss, or persistent fever.
What diagnostic approaches are used to determine the cause of swollen submandibular lymph nodes?
Doctors typically perform a physical exam and review your medical and dental history. If the cause is unclear, they may order blood tests, an ultrasound, or a fine-needle aspiration biopsy to examine the node’s tissue.
What are the treatment options for swollen submandibular lymph nodes?
Treatment targets the root cause, such as antibiotics for bacterial infections or supportive care for viral ones. If the swelling is due to an inflammatory condition, a doctor might prescribe steroids or other specific therapies.
Can swollen submandibular lymph nodes be prevented?
Maintaining excellent oral hygiene and treating dental problems promptly can prevent many infections that lead to swelling. Staying current on vaccinations and frequent handwashing also reduces the risk of viral triggers.
Are swollen submandibular lymph nodes a sign of a serious condition?
While usually a harmless “reactive” sign of the immune system working, they can occasionally indicate lymphoma or metastatic cancer. However, most cases are temporary responses to minor infections.
How can I manage swollen submandibular lymph nodes at home?
Applying a warm compress to the area can soothe tenderness and improve circulation. Over-the-counter anti-inflammatories like ibuprofen can also help reduce discomfort while your body recovers from the underlying infection.
Can submandibular gland swelling be related to lymph node swelling?
Yes, because they are located in the same anatomical space, an infection in the salivary gland often triggers the nearby lymph nodes. Conversely, a severe lymph node infection can sometimes cause secondary inflammation in the adjacent gland.
