The recovery period after wisdom tooth removal goes smoothly for most patients — even for those with impacted teeth. However, in rare cases, complications may occur, including a rise in temperature after the removal of a wisdom tooth. Therefore, after the extraction of third molars, it is important to monitor symptoms.
Although tooth extraction is a routine dental procedure, some discomfort, including a mild fever, is normal. However, understanding the difference between common side effects and potential complications can be key to a quick recovery.
An elevated temperature is not uncommon after wisdom tooth removal, and a mild fever is not a cause for concern. This is how the body reacts to the procedure. Usually, the temperature subsides within a few days.
However, if the temperature rises above 38°C (100.4°F), contact your doctor immediately — you may have an infection that requires antibiotic treatment. The situation becomes more serious if a high fever is accompanied by chills, joint pain, or other alarming symptoms.
Common signs of infection after tooth extraction
Infection can sometimes develop after tooth extraction, especially in more complex cases such as wisdom tooth removal.
Signs of infection may include:
- Elevated temperature;
- Unpleasant taste or odor in the mouth;
- Persistent pain. As healing progresses after wisdom tooth removal, the pain should gradually decrease until it disappears. Pain relievers can help manage discomfort. Pain usually subsides within three to four days. If the pain begins to worsen a few days after the procedure, consult your doctor;
- Persistent numbness in the mouth. During the first few hours after third molar removal, mild numbness may persist. It should disappear quickly. If your tongue, lip, jaw, or face remains partially or completely numb for an extended period, this may be a symptom of paresthesia (a tingling, itching, or burning sensation without visible physical irritation) or nerve damage;
- Difficulty swallowing or breathing;
- Swelling that worsens over time. After third molar removal, some swelling is expected. Applying an ice pack to the cheek can help reduce swelling. If swelling does not decrease by the fourth or fifth day after the procedure, it may be a sign of infection;
- Continued bleeding at the extraction site. Minor bleeding may occur within 24 hours after extraction. You can place a piece of clean gauze on the extraction site, gently bite down, and hold it for 30 minutes. By the next day, a blood clot should form at the surgical site. If significant bleeding persists, you should consult a doctor. Proper healing may require suturing the site;
- Discharge of pus from the extraction site is another possible sign of a postoperative infection. If the discharge is not accompanied by pain, the gum tissues may not be infected, but the safest step is to consult a doctor for a professional opinion;
- Dry socket. Dry socket occurs when the protective blood clot at the extraction site is dislodged, exposing nerves and bone. Symptoms include facial pain radiating to the ear, unpleasant taste, and odor. This can be prevented with proper care.
After wisdom tooth removal, patients may also experience nausea, fatigue, or dizziness.
These symptoms may result from anesthesia, pain medications, or the body’s response to the procedure.
Post-operative care tips after wisdom tooth removal
Following these recommendations will help ease recovery and minimize the risk of complications:
- Rest and avoid strenuous activity during the first 24 hours;
- Apply a cold compress to reduce swelling;
- Take prescribed pain medications;
- Follow your dentist’s care instructions, including dietary recommendations.
What to avoid after tooth extraction
Here are several things to avoid:
- Using a straw — suction can dislodge the blood clot;
- Touching the extraction site — avoid contact to reduce bacterial exposure;
- Chewing near the extraction site for at least 24 hours;
- Smoking or alcohol for at least 48 hours after extraction;
- Rinsing your mouth on the day of the procedure.
Foods to avoid after wisdom tooth removal
Your diet plays a crucial role in recovery.
Avoid the following to promote proper healing:
- Spicy or acidic foods — they may irritate the extraction site and cause discomfort;
- Hard or crunchy foods — chips, nuts, and similar products can damage healing tissues;
- Hot foods and drinks — they can cause swelling and irritation.
After tooth extraction, it is important to eat properly to speed up healing and minimize the risk of complications such as fever.
What you can eat after tooth extraction:
- Soft foods: mashed potatoes and applesauce;
- Smoothies: blended fruits and yogurt can be nutritious and hydrating (avoid using a straw);
- Yogurt: rich in probiotics that may support the immune system;
- Soup: warm (not hot) broths or pureed soups provide nutrients and hydration. Avoid thick soups that require chewing;
- Soft-boiled eggs, omelet, or poached eggs;
- Oatmeal;
- Avocado;
- Water: hydration is essential for recovery — drink plenty of water;
- Herbal teas.
If you experience persistent severe pain, high fever, or symptoms such as swelling that does not subside, consult your doctor.
