Introduction to Signs of Wisdom Tooth Infection
A wisdom tooth infection, also called pericoronitis, can quickly lead to serious complications if left untreated. Infections can spread to nearby teeth, the jawbone, and even the bloodstream, turning what starts as minor discomfort into a potential emergency.
At Prostho Endo Dental Specialists, located in North Bethesda, Maryland, we specialize in diagnosing and treating wisdom tooth infections for patients in Rockville, Potomac, Bethesda, and surrounding areas.
In this guide, we’ll cover:
- Common causes of wisdom tooth infections
- Warning signs you shouldn’t ignore
- When to see a dentist for treatment
- How to prevent wisdom tooth infections from happening
What Causes Wisdom Tooth Infections?
Common Causes of Wisdom Tooth Infections:
- Impacted Wisdom Teeth – Teeth that fail to fully emerge and remain stuck beneath the gum, creating pressure, swelling, and infection.
- Partially Erupted Wisdom Teeth – When a tooth partially breaks through the gum, it leaves a small opening where bacteria can enter.
- Poor Oral Hygiene – Since wisdom teeth are located at the very back of the mouth, they are harder to clean, increasing the risk of infection and decay.
- Gum Flaps(Pericoronitis) – Sometimes, a flap of gum tissue partially covers the wisdom tooth, creating the perfect place for bacteria to thrive.
- Cavities & Decay – Wisdom teeth are difficult to reach with a toothbrush and floss, making them prone to cavities, which can lead to infection if untreated. Because wisdom teeth are so hard to clean, they are more susceptible to infection than other teeth.

7 Warning Signs of a Wisdom Tooth Infection
– A dull ache or sharp pain near your wisdom tooth is often the first sign of infection.
– The pain may spread to your jaw, ear, or even down your neck.
2. Red, Swollen, or Bleeding Gums
– Infected wisdom teeth cause gum inflammation, leading to redness, tenderness, and bleeding when brushing or flossing.
– You may also experience difficulty chewing on that side of your mouth.
3. Difficulty Opening Your Mouth(Trismus)
– If swelling spreads, it can stiffen the jaw muscles, making it painful or even impossible to open your mouth fully.
– This condition is called trismus and is a sign that the infection is spreading.
4. Bad Breath or a Foul Taste in Your Mouth
– A foul odor or bad taste in your mouth—even after brushing—can be a sign of pus draining from an infected wisdom tooth.
5. Fever and General Discomfort
– Fever, chills, or body aches mean your body is fighting off an infection.
– If you’re feeling sick or fatigued, the infection may be spreading beyond your mouth.
6. Swollen Lymph Nodes Under Your Jaw
– Your body’s immune system fights infection by activating lymph nodes under the jaw, making them swollen and tender.
7. Pus Around the Tooth
– If you notice white or yellow pus near your wisdom tooth, it’s a clear sign of infection.
– Pus buildup indicates severe infection and requires urgent dental care.

When to See a Dentist for a Wisdom Tooth Infection
- Abscess formation (a painful pocket of pus)
- Severe swelling that affects breathing
- Systemic infection(sepsis), which can be life-threatening
- Mild symptoms? Schedule a dental appointment ASAP.
- Severe pain, fever, or swelling? Seek urgent dental care or visit an emergency dentist.
Treatment Options for Wisdom Tooth Infections
Common Treatment Options Include:
- Antibiotics – Prescribed to fight infection, but they don’t fix the underlying issue.
- Deep Cleaning – Removes trapped bacteria, plaque, and food debris from around the tooth.
- Drainage of Abscess – If pus has built up, it may need to be drained to relieve pressure and pain.
- Wisdom Tooth Extraction – The most effective long-term solution if the tooth is causing repeated infections.
What to Expect Before and After Wisdom Tooth Extraction
- A cone beam CT scan is taken to evaluate the tooth’s position and its proximity to nerves.
- Your dentist will discuss sedation options to keep you comfortable.
- Pain and swelling typically last 2-3 days.
- Most patients experience full healing within a week.
- Some may need a follow-up visit for suture removal, while others have dissolvable stitches.
How to Prevent Wisdom Tooth Infections
- Maintain Good Oral Hygiene – Brush, floss, and use antibacterial mouthwash.
- Schedule Regular Dental Checkups – X-rays can detect potential problems early.
- Monitor Wisdom Teeth Growth – If they are impacted, removal may be necessary before they cause an infection.
