Swollen Jaw After Cavity Treatment: What You Need to Know

Swelling of the jaw after seeing a dentist for cavities?

Hello Doctor: A few days ago, when I visited the dentist, the doctor informed me that I needed a root canal treatment for my cavity (on the right molar).
However, I was too anxious to proceed at that time, so the dentist only filled the tooth and prescribed pain relievers and anti-inflammatory medication.
Three days later, I started experiencing pain below the right molar, and since then, I have been taking the pain and anti-inflammatory medications.
Now, after seven days, my tooth and gums are not painful and there is no swelling, but my jaw has swollen and is painful, and I cannot open my mouth wide.
There is also pain when I bite down.
I researched online and am unsure if this could be lymphadenopathy or if it is related to not having the root canal treatment.
Which specialist should I see first? Thank you.

Dear Ms.
Zoe,
Hello! As mentioned, the situation is somewhat serious and may be cellulitis.
Debridement may be necessary.
If you develop a high fever and your white blood cell count exceeds 10,000, hospitalization for treatment will be required.
Please consult with a dentist or an infectious disease specialist.
Make sure to communicate closely with your physician.
Thank you! Wishing you safety!
Sincerely,
Dr.

More Info

Swollen jaw after dental treatment can be concerning, especially when accompanied by pain and limited mouth opening. Based on your description, it seems that you have undergone a dental procedure for a cavity, but you opted not to proceed with the root canal treatment. Instead, you received a filling and were prescribed pain and anti-inflammatory medication. Now, a week later, you are experiencing swelling in your jaw, pain, and difficulty opening your mouth, while the tooth and gums themselves are not painful.

The symptoms you are experiencing could be due to several factors. One possibility is that the swelling in your jaw could be related to an infection. When a cavity is deep, it can reach the pulp of the tooth, leading to pulpitis or even an abscess if bacteria invade the pulp. If the infection is not treated, it can spread to the surrounding tissues, including the jaw, resulting in swelling and pain. The fact that you are unable to open your mouth fully and are experiencing pain when biting down could indicate that the infection is affecting the muscles or tissues around the jaw.

Another possibility is that the swelling could be related to lymphadenopathy, which is the enlargement of lymph nodes due to infection or inflammation. The lymph nodes in the neck and jaw area can become swollen in response to dental infections, and this could explain the swelling you are experiencing.

Given your symptoms, it is crucial to seek medical attention promptly. You should consider visiting a dentist first, as they are specialized in diagnosing and treating dental issues. The dentist can evaluate the condition of your tooth and surrounding tissues, possibly taking X-rays to check for any underlying infections or abscesses. If an infection is confirmed, they may recommend further treatment, which could include a root canal or extraction of the affected tooth, along with antibiotics to manage the infection.

If the dentist determines that the issue is beyond their scope, or if they suspect a more systemic issue, they may refer you to an oral surgeon or an ear, nose, and throat (ENT) specialist. These specialists can provide further evaluation and treatment if there are complications related to the jaw or if the swelling is due to lymphatic issues.

In the meantime, it is essential to continue taking any prescribed medications as directed and to avoid any activities that may exacerbate the pain or swelling. Applying a warm compress to the swollen area may help alleviate discomfort, and maintaining good oral hygiene is crucial to prevent further complications.

In summary, your swollen jaw after cavity treatment could be due to an infection or lymphadenopathy. It is advisable to see a dentist as soon as possible for a thorough evaluation and appropriate treatment. Early intervention is key to preventing further complications and ensuring a swift recovery.
