Persistent Pain and Fever After Wisdom Tooth Extraction: Possible Complications? - Dentistry

Persistent pain and fever after wisdom tooth extraction?


Hello, doctor.
I had my upper right wisdom tooth extracted on April 19 due to gum inflammation, and there were no stitches.
It has been almost three weeks, and I am still experiencing pain.
Sometimes the pain is so severe at night that I can't sleep, and I also feel unusual sensations in the nerves on the right side of my neck.
Recently, I have been experiencing recurrent fevers when eating, sometimes reaching around 38.5 degrees Celsius.
When I returned for a follow-up, the doctor mentioned that the wound is larger and may be healing more slowly, but did not observe any signs of inflammation.
They only prescribed pain relief and antibiotics.
Could there be other possible complications?

After wisdom tooth extraction, it is not uncommon to experience persistent pain and even fever, especially if the extraction site is healing slowly or if there are complications. Given your symptoms of ongoing pain, fever reaching up to 38.5 degrees Celsius, and unusual sensations in your neck, it is essential to consider several potential complications that could arise from the procedure.

1. Dry Socket (Alveolar Osteitis): This is one of the most common complications following tooth extraction. It occurs when the blood clot that forms in the socket is dislodged or dissolves before the wound has healed. This can expose the underlying bone and nerves, leading to severe pain that may radiate to the neck or ear. Patients often describe the pain as throbbing and may experience a bad taste in their mouth. Dry socket typically occurs a few days after the extraction and can be associated with a foul odor.

2. Infection: The presence of fever and persistent pain could indicate an infection at the extraction site. Even if your dentist did not observe signs of infection during your follow-up visit, it is possible for an infection to develop later. Symptoms of infection may include swelling, redness, increased pain, and pus discharge from the extraction site. Antibiotics are often prescribed to manage infections, but if symptoms persist or worsen, further evaluation may be necessary.

3. Nerve Injury: While rare, it is possible for the extraction of wisdom teeth to result in nerve damage, particularly if the tooth is located close to the inferior alveolar nerve. This could lead to sensations of tingling, numbness, or pain radiating to the neck or jaw. If you are experiencing unusual sensations in your neck, it may be worth discussing this with your dentist or an oral surgeon.

4. Delayed Healing: Factors such as smoking, pre-existing medical conditions (like diabetes), or even the size of the extraction site can affect healing. If the extraction site is larger than usual, it may take longer to heal, leading to prolonged pain and discomfort.

5. Muscle Strain: The act of keeping your mouth open for an extended period during the extraction can lead to muscle strain in the jaw and neck. This could explain the unusual sensations in your neck, especially if you have been clenching your jaw or experiencing discomfort while eating.

Given your symptoms, it is crucial to follow up with your dentist or an oral surgeon for a thorough examination. They may recommend imaging studies, such as an X-ray, to assess the healing process and rule out complications like dry socket or infection. Additionally, if you are not responding to the prescribed antibiotics or pain management, your healthcare provider may need to adjust your treatment plan.

In summary, while some discomfort and mild fever can be expected after wisdom tooth extraction, persistent pain and significant fever warrant further investigation. It is essential to communicate openly with your healthcare provider about your symptoms and any changes you experience. Early intervention can help prevent complications and promote a smoother recovery.
