After wisdom tooth extraction


Hello Doctor, I had my lower left wisdom tooth extracted on Monday (which coincided with the start of my menstrual period).
The doctor prescribed medication for three days, and everything was normal until Saturday afternoon when I developed a sore throat and then a fever.
I took some antipyretics on my own.
On Monday, I returned for a follow-up appointment to have the stitches removed.
I asked the doctor about my condition, and he said the wound looked normal, but advised me to see an ENT specialist regarding the fever.
After visiting the ENT, I felt a bit better, but occasionally I experience sharp ear pain and headaches.
I'm still concerned about the possibility of a bacterial infection due to the tooth extraction.
If there were an infection, what symptoms should I look out for? Thank you.

If there is no severe infection such as acute pericoronitis or cellulitis before the extraction of a horizontally impacted wisdom tooth, and the wound is properly cleaned after the procedure, there may be only mild inflammation post-surgery that should not affect the throat.
However, if there is throat inflammation after the surgery, it is important to assess the severity of any potential wound infection.
It is recommended to have regular follow-up appointments to monitor the healing of the wound.

After undergoing a wisdom tooth extraction, it's not uncommon to experience various symptoms, some of which may raise concerns about potential complications or infections. Understanding these symptoms and their implications is crucial for managing your recovery effectively.

Firstly, it’s important to recognize that the extraction of a wisdom tooth, especially if it was impacted or required surgical intervention, can lead to a range of post-operative symptoms. Commonly reported issues include swelling, pain, and discomfort in the extraction site, which can radiate to nearby areas such as the jaw, ear, and throat. The presence of fever, as you mentioned, can also be a significant indicator of an underlying issue.

In your case, the onset of a sore throat and fever several days after the extraction could suggest a few possibilities. While the dentist noted that the extraction site appeared normal, it’s essential to consider that infections can sometimes develop in the days following a procedure, especially if bacteria were introduced during the extraction or if there was an existing infection that was exacerbated by the procedure. Symptoms of infection may include:
1. Increased Pain and Swelling: While some pain and swelling are expected after surgery, a significant increase in these symptoms, particularly if they worsen after the first few days, can indicate an infection.

2. Fever: A low-grade fever can be a normal response to surgery, but a persistent or high fever (generally over 101°F or 38.3°C) can be a sign of infection.

3. Pus or Discharge: If you notice any pus or foul-smelling discharge from the extraction site, this is a clear sign of infection and requires immediate medical attention.

4. Difficulty Swallowing or Breathing: If you experience significant difficulty swallowing or breathing, this could indicate swelling that is compromising your airway, which is a medical emergency.

5. Ear Pain: The ear pain you described can be referred pain from the jaw or throat, but if it is severe or accompanied by other symptoms, it may warrant further investigation.

6. Persistent Headaches: While headaches can occur post-surgery due to tension or stress, persistent or worsening headaches could indicate a more serious issue.

Given that you have already consulted with an ENT specialist, it’s wise to follow their recommendations. They may perform a thorough examination to rule out any infections in the throat or sinuses, which can sometimes occur after dental procedures, especially if the roots of the teeth are close to the sinus cavities.

In terms of management, it’s crucial to maintain good oral hygiene to prevent infections. This includes gently rinsing your mouth with warm salt water after 24 hours post-surgery, avoiding vigorous rinsing or spitting, and refraining from using straws, which can dislodge the blood clot and lead to dry socket—a painful condition that can occur after tooth extractions.

If you continue to experience symptoms such as fever, increased pain, or any new symptoms, it’s essential to return to your dentist or seek further medical evaluation. They may consider imaging studies, such as X-rays, to assess the extraction site and surrounding structures for any signs of complications.

In summary, while some discomfort and symptoms are expected after wisdom tooth extraction, persistent or worsening symptoms should not be ignored. Monitoring your symptoms closely and maintaining open communication with your healthcare providers will help ensure a smooth recovery and address any potential complications promptly.
