Wisdom teeth removal is one of the most common oral surgery procedures—but what happens when something goes wrong after the extraction? Knowing the signs of infected wisdom teeth (or an infected extraction site) can mean the difference between a quick course of antibiotics and a more serious complication that requires emergency care.
At Eggleston OMS in Austin, Texas, our board-certified oral surgeons see post-extraction complications regularly. This guide covers what is normal after wisdom teeth removal, what is cause for concern, and when to call your oral surgeon immediately.
What Does Normal Healing Look Like?
In the first 24–72 hours after wisdom teeth removal, it is normal to experience: swelling (peaks at 48–72 hours), mild to moderate pain, mild bleeding that slows to a light ooze, a blood clot forming in the socket, bruising on the jaw or neck, and difficulty opening the mouth wide (trismus). By days 3–7, swelling should reduce and pain should improve. If your symptoms are getting worse after day 3, that is a red flag.
Signs of Infected Wisdom Teeth or an Infected Extraction Site
1. Worsening Pain After Day 3
Pain should improve after the first 48–72 hours. If your pain is escalating—especially radiating toward the ear or jaw—this is not normal. Escalating pain on days 3–5 is the most common early signal of either infection or dry socket (alveolar osteitis). Dry socket occurs when the blood clot dissolves or dislodges before the socket heals. Learn more about whether sneezing can cause dry socket and how to protect the clot during recovery.
2. Swelling That Spreads or Does Not Improve
Swelling that continues to grow after day 3, or that spreads down the neck or toward the throat, indicates a possible spreading infection. Cellulitis and Ludwig’s angina (a rare but serious deep neck infection) can develop rapidly and require immediate emergency care.
3. Fever (100.4°F or Higher)
A fever above 100.4°F that appears on days 2–5—or that does not resolve—strongly suggests bacterial infection and requires evaluation. A low-grade temperature (99–100°F) in the first 24 hours can be a normal inflammatory response.
4. Pus or Discharge from the Socket
Yellow, green, or gray discharge from the extraction site is not normal. If you see or taste any discharge from the socket, contact your oral surgeon the same day. This is a direct sign of active bacterial infection.
5. Persistent Foul Taste or Severe Bad Breath
A persistent, strong foul taste or severe bad breath starting on days 3–7 often signals an infected socket or dry socket with bacterial contamination. Patients frequently assume this is just healing—it is not. Get it checked.
6. Difficulty Swallowing or Worsening Trismus
If your ability to open your mouth is decreasing after day 3, or if swallowing becomes painful or difficult, this could indicate a spreading abscess. This is an emergency—call your oral surgeon or go to an emergency room immediately.
7. Red Streaks in the Surrounding Gum Tissue
Red streaks radiating from the extraction site along the gum line can indicate cellulitis—a bacterial soft-tissue infection that can spread rapidly. If you notice streaking redness or swelling that is hardening and hot to the touch, seek care immediately.
Signs of Infected Wisdom Teeth That Have Not Been Removed
Infection does not only happen after extraction—it can also develop in wisdom teeth that are still in place. Pericoronitis (infection of the tissue flap partially covering an erupting wisdom tooth) is one of the most common reasons patients need emergency oral surgery. Signs include persistent throbbing pain at the back of the mouth, swollen red gum flap behind the last molar, difficulty chewing, discharge when gum flap is pressed, jaw stiffness, and fever.
If you have not had your wisdom teeth evaluated and you are experiencing these symptoms, delaying removal only increases the risk of serious infection. According to the American Association of Oral and Maxillofacial Surgeons (AAOMS), impacted wisdom teeth carry an increasing risk of infection, cyst formation, and adjacent tooth damage over time.
What to Do If You Suspect Infection
- Call your oral surgeon’s office first. At Eggleston OMS, we prioritize post-extraction complications and will get you in quickly.
- Do not stop prescribed antibiotics on your own. Stopping early is a common cause of rebound infection.
- Rinse gently with warm salt water (1/4 tsp salt in 8 oz water) 3–4 times daily.
- If you have difficulty breathing, swallowing, or swelling spreading to your neck—go to the emergency room immediately.
How to Prevent Infection After Wisdom Teeth Removal
- No smoking for at least 72 hours (ideally 2 weeks)
- No straws—suction dislodges the blood clot
- Eat soft foods only for the first 3–5 days. See our complete guide on what to eat after tooth extraction.
- Rinse gently with salt water starting 24 hours post-op
- Take all prescribed medications on schedule
- Attend your follow-up appointment even if you feel fine — review our full extraction post-operative instructions for a complete recovery checklist
