10 Signs You May Have an Infection After a Tooth Extraction

Some discomfort is normal after surgery, especially within the first few days. However, if your symptoms worsen instead of improving or new problems develop, it may be time to contact your dentist.

Here are 10 signs to watch for:

1. Pain that Gets Worse Instead of Better

Initial soreness should subside gradually over the next few days. If pain returns or intensifies after it started to improve, it could be a sign of infection.

2. Swelling That Increases After 48 Hours

Some swelling is expected. However, if your face feels puffier on day three than it did on day one, especially if the puffiness is spreading, it may be a concern.

3. Pus or Discharge

If you notice white or yellow fluid leaking from the extraction site, contact your dentist immediately. This could mean bacteria have entered the area.

4. Red or Inflamed Gums

Gums may appear slightly red early in the healing process, but intense redness, puffiness, or heat around the wound should be checked.

5. Bad Breath or a Sour Taste

An unpleasant smell or a persistent bitter taste in your mouth can indicate bacterial buildup or an infected socket.

6. Bleeding That Continues Beyond a Day

Light bleeding is normal for several hours after the procedure. If it restarts or doesn’t slow down within a day, it should be addressed.

7. Fever

If your body temperature rises above 100.4°F, especially accompanied by chills or fatigue, contact your dentist. This is your body’s way of signaling that something isn’t right.

8. Swollen Glands

Tender areas under your jaw or in your neck may point to an immune response. Swollen lymph nodes are often a sign of infection.

9. Difficulty Chewing, Talking, or Swallowing

If moving your jaw feels unusually painful or stiff, especially a few days after surgery, it’s worth discussing with your dentist.

10. Numbness in the Face or Jaw

Sudden numbness or tingling after intense pain can be a red flag. It could mean the infection is affecting nearby nerves or tissues.

Common Causes of Post-Extraction Infection

Infections usually stem from bacteria entering the wound. This can happen if:

  • The blood clot becomes dislodged
  • Smoking or vaping interferes with healing
  • The socket isn’t cleaned as instructed
  • You skip antibiotics or aftercare steps
  • The immune system is already weakened

At Summit Dental Partners, we’ll let you know exactly how to clean the area and what to avoid during healing. In some cases, we may prescribe antibiotics to prevent problems before they begin.

What’s the Difference Between Dry Socket and Infection?

Dry socket and infection are distinct issues, although they may initially present with similar symptoms.

Dry Socket Infection
Happens when the blood clot is lost too early Caused by bacteria entering the wound
Exposes the underlying bone May include pus, fever, or swelling
Often begins with sharp pain 2–3 days after surgery Pain may come and go or steadily worsen
Usually not accompanied by pus or swelling May include bad taste, smell, or gland swelling

If you’re not sure which you’re experiencing, don’t guess. Call your provider for an evaluation.

How Long Should Pain Last After a Tooth Extraction?

Here’s a general timeline for pain after an extraction:

  • Simple extractions: 2 to 3 days of soreness
  • Wisdom teeth: 3 to 4 days due to deeper roots
  • Pain should improve steadily each day
  • By one week, most pain is gone

If you feel worse after day four or five, or if pain is interfering with sleep or eating, it’s time to call.

How Long Do Dissolvable Stitches Last?

If we used dissolvable stitches, you can expect them to:

  • Begin breaking down after 5 to 7 days
  • Occasionally, fall out in as little as 2 days
  • Fully dissolve within 1 to 2 weeks

Still seeing stitches after 14 days? Give us a call. It’s usually not urgent, but we’ll be happy to take a look.

Tips to Prevent Infection After a Tooth Extraction

Prevention is the best medicine. Follow these simple rules to lower your risk:

  • Don’t smoke, vape, or use tobacco products
  • Avoid drinking through a straw
  • Rinse gently with salt water or a prescribed solution
  • Skip spicy, acidic, or crunchy foods for a few days
  • Avoid alcohol and carbonated drinks
  • Brush gently but thoroughly — don’t skip oral care
  • Take antibiotics exactly as prescribed
  • Rest for the first 24 hours and limit strenuous activity

If you notice anything unusual, don’t wait it out. Early treatment makes all the difference.

  • Pain gets worse after improving

  • Swelling increases instead of going down
  • You have a fever, chills, or swollen glands
