Can a toothache affect the throat?


A few weeks ago, I had an infection in the root of my lower right tooth.
I noticed an increase in the number of lymph nodes on the right side.
After undergoing partial root canal treatment, I started experiencing pain in my temple and ear, as well as discomfort in the lymph nodes on the right side of my lower jaw.
Recently, I've also noticed occasional vague pain deep in my throat (around the center of my neck and near the clavicle), a sensation of tightness near the clavicle, and some pain associated with phlegm.
This does not feel like a cold, as I have no other cold symptoms, and the pain is not related to swallowing.
I have to wait another month for my next dental appointment, and I would like to know if these symptoms are normal reactions to dental pain or if it is necessary to see another doctor.
Thank you.

Hello: The symptoms indeed resemble lymphadenitis caused by a dental infection, along with ear pain and headaches.
If the symptoms continue to improve, you may observe them at home.
However, if you experience fever or if the symptoms worsen, it is advisable to visit a general clinic or an otolaryngology clinic for examination and treatment.
Wishing you safety and health.
Sincerely, Dr.
Jue-Yi Cheng, Director of the Department of Otolaryngology, Taoyuan Hospital, Ministry of Health and Welfare.

Tooth pain can indeed have a significant impact on various areas of the body, including the throat. This connection is primarily due to the intricate network of nerves and the close proximity of anatomical structures in the head and neck region. When you experience tooth pain, especially from an infection or inflammation, it can lead to referred pain in nearby areas, including the throat, ears, and lymph nodes.

In your case, the right lower tooth root infection likely triggered a cascade of symptoms. The infection can cause inflammation in the surrounding tissues, leading to swelling and pain in the lymph nodes, which are part of your immune response to infection. The lymph nodes in the neck and under the jaw can become tender and enlarged when fighting off an infection, which may explain the pain you feel in your throat and the discomfort in your jaw and temple areas.

The pain you are experiencing in the throat, particularly in the area around the collarbone, could be related to the same infection affecting your tooth. This is often referred to as referred pain, where pain is perceived in an area different from the source of the pain. The throat pain you describe, especially if it is not associated with swallowing or other typical symptoms of a throat infection, may indeed be linked to the dental issue.

It is also important to consider that dental infections can sometimes lead to more serious complications if left untreated. For example, an abscessed tooth can lead to the spread of infection to other areas, including the throat, which can cause more severe symptoms and complications. The presence of phlegm and the sensation of something being "stuck" in your throat could also indicate that the infection is affecting the surrounding tissues, leading to irritation or inflammation.

Given that you have a month until your next dental appointment, it is advisable to seek medical attention sooner rather than later, especially since you are experiencing new symptoms like throat pain and discomfort in the lymph nodes. A healthcare provider can perform a thorough examination, possibly including imaging studies, to assess the extent of the infection and determine if additional treatment is necessary. They may also evaluate whether you need antibiotics or other interventions to manage the infection and alleviate your symptoms.

In summary, while it is common for dental issues to cause referred pain in the throat and surrounding areas, the presence of new symptoms warrants further evaluation. It is essential to address any potential complications from the tooth infection promptly to prevent further health issues. Seeking medical advice sooner can help ensure that you receive the appropriate care and treatment.
