Wisdom tooth infections are more common than you might think — and they can quickly turn from a minor annoyance into a serious health concern. If you’re experiencing pain, swelling, or discomfort around your back molars, you might be dealing with an infected wisdom tooth that needs immediate attention.
Understanding what causes wisdom tooth infections, recognizing the symptoms, and knowing when to seek emergency dental care can save you from severe complications. In this comprehensive guide, we’ll walk you through everything you need to know about treating wisdom tooth infections and protecting your oral health.
Understanding Wisdom Tooth Infections
Wisdom tooth infections develop when bacteria invade the gum tissue surrounding your third molars. These infections are particularly common with impacted or partially erupted wisdom teeth, where food particles and bacteria become trapped in hard-to-clean areas. Understanding the root causes helps you recognize symptoms early and seek appropriate treatment before complications arise.
What Is a Wisdom Tooth Infection?
A wisdom tooth infection, also called pericoronitis, occurs when bacteria accumulate around a partially erupted wisdom tooth or an impacted wisdom tooth. The infection typically develops in the gum tissue surrounding the tooth, creating a pocket where food particles and bacteria become trapped.
Third molars (wisdom teeth) usually emerge between ages 17 and 25, but they often don’t have enough room to grow properly. When a wisdom tooth becomes impacted — meaning it’s trapped beneath the gum line or growing at an angle — it creates the perfect environment for bacterial growth and infection.
Why Do Wisdom Teeth Get Infected?
Several factors contribute to wisdom tooth infections:
Partial Eruption: When a wisdom tooth only partially breaks through the gums, it creates a flap of tissue where bacteria and food debris collect, leading to infection.
Impaction: Impacted wisdom teeth that can’t fully emerge are prone to infection because they’re difficult to clean and maintain.
Poor Oral Hygiene: The location of wisdom teeth at the back of your mouth makes them challenging to brush and floss properly, increasing infection risk.
Crowded Teeth: When there isn’t enough space in your jaw, wisdom teeth may push against neighboring teeth, creating pockets where bacteria thrive.
Tooth Decay: Cavities in wisdom teeth can quickly progress to infection if left untreated.
Recognizing the Warning Signs: Symptoms of an Infected Wisdom Tooth
Early detection is crucial for preventing complications. Here are the common symptoms of a wisdom tooth infection:
Pain and Discomfort
Throbbing pain in the back of your mouth is often the first sign. The pain may radiate to your jaw, ear, or neck and typically worsens when chewing or applying pressure to the area. Some patients describe it as a constant, severe toothache that doesn’t respond to over-the-counter pain relievers.
Swelling and Inflammation
Swollen gums around the wisdom tooth are a telltale sign of infection. You may notice:
- Red, inflamed gum tissue covering or surrounding the tooth
- Swelling in your jaw or face on the affected side
- Difficulty opening your mouth fully (trismus)
- A swollen lymph node under your jaw or in your neck
Bad Taste and Odor
An infected wisdom tooth often produces pus or discharge with an unpleasant taste. You might experience persistent bad breath (halitosis) that doesn’t improve with brushing or mouthwash.
Fever and Systemic Symptoms
When the infection spreads, you may develop:
- Fever or chills
- Headache
- Difficulty swallowing
- Jaw stiffness
- General feeling of being unwell
If you experience fever, difficulty breathing, or severe swelling that extends to your face or neck, seek emergency dental care immediately, as these may indicate a serious infection spreading beyond the tooth.
Immediate Steps: What to Do When You Suspect an Infection
Acting quickly when you notice wisdom tooth infection symptoms can prevent serious complications and reduce your discomfort. While professional dental care is essential, there are important immediate actions you can take to manage symptoms and protect your health until you receive treatment from your dentist.
Don’t Wait — Contact Your Dentist
The first and most important step is to schedule a dental appointment as soon as possible. Wisdom tooth infections don’t heal on their own and require professional treatment. Even if your symptoms seem mild, early intervention prevents the infection from worsening.
At-Home Relief While Waiting for Your Appointment
While you’re waiting to see your dentist, these home remedies can provide temporary relief:
Saltwater Rinses: Mix half a teaspoon of salt in warm water and gently rinse your mouth several times daily. This natural remedy reduces inflammation and helps clean the infected area.
Cold Compress: Apply an ice pack to the outside of your cheek for 15-20 minutes to reduce swelling and numb pain.
Over-the-Counter Pain Medication: Ibuprofen or acetaminophen can help manage pain and reduce inflammation. Follow the dosage instructions carefully.
Elevate Your Head: Sleep with your head elevated on pillows to reduce blood flow to the area and minimize throbbing pain.
Maintain Oral Hygiene: Gently brush your teeth, including the area around the infected wisdom tooth, but avoid aggressive brushing that might irritate the infection.
What NOT to Do
- Don’t ignore the symptoms hoping they’ll disappear
- Avoid using aspirin directly on the gums, as it can cause chemical burns
- Don’t try to lance or drain the infection yourself
- Avoid hard, crunchy, or sticky foods that could aggravate the area
- Don’t smoke or use tobacco products, which delay healing
Professional Treatment Options for Wisdom Tooth Infections
Your dentist will create a customized treatment plan based on the severity of your infection and the condition of your wisdom tooth. Professional intervention is critical because untreated infections can spread to surrounding tissues and cause serious health complications. Here’s what to expect during your dental visit.
Diagnosis and Examination
Your dentist will perform a thorough examination, including:
- Visual inspection of the affected area
- Dental X-rays to assess the position of the wisdom tooth and extent of infection
- Evaluation of surrounding teeth and bone structure
- Assessment of infection severity
Antibiotics for Infection Control
If you have an active infection, your dentist will likely prescribe antibiotics to eliminate the bacteria. Common antibiotics for tooth infections include:
- Amoxicillin
- Penicillin
- Clindamycin (for patients with penicillin allergies)
- Metronidazole
It’s crucial to complete the entire course of antibiotics, even if symptoms improve, to ensure the infection is fully eliminated and prevent antibiotic resistance.
Drainage and Cleaning
For abscessed wisdom teeth with pus accumulation, your dentist may need to:
- Drain the abscess to remove infected fluid
- Clean the area thoroughly to remove debris
- Irrigate the pocket with antiseptic solution
Wisdom Tooth Extraction
In most cases of recurrent infections or impacted wisdom teeth, extraction is the best long-term solution. Wisdom tooth removal prevents future infections and protects adjacent teeth from damage.
Simple Extraction: If the tooth has fully erupted, your dentist can remove it with local anesthesia in a straightforward procedure.
Surgical Extraction: Impacted wisdom teeth require oral surgery where the dentist makes an incision in the gum tissue and may need to remove bone or divide the tooth into sections for easier removal.
The procedure is typically performed under local anesthesia, sedation, or general anesthesia, depending on the complexity and your comfort level.
Post-Treatment Care: Ensuring Proper Healing
Proper aftercare following wisdom tooth treatment or extraction is crucial for preventing complications like infection, dry socket, and prolonged pain. Following your dentist’s instructions carefully promotes faster healing and reduces discomfort. Here’s your complete guide to recovery and what warning signs to watch for.
Recovery After Extraction
Following wisdom tooth extraction, proper aftercare is essential:
First 24 Hours:
- Bite on gauze pads to control bleeding
- Apply ice packs to reduce swelling
- Rest and avoid strenuous activities
- Don’t rinse, spit forcefully, or use straws (to prevent dry socket)
Days 2-7:
- Gently rinse with warm saltwater after meals
- Take prescribed pain medication and antibiotics
- Eat soft foods like yogurt, smoothies, mashed potatoes, and soup
- Continue gentle oral hygiene while avoiding the extraction site
Warning Signs of Complications
Contact your dentist immediately if you experience:
- Severe pain that worsens after 2-3 days
- Heavy bleeding that doesn’t stop
- High fever (above 101°F)
- Difficulty swallowing or breathing
- Pus or foul-smelling discharge
- Dry socket symptoms (severe pain 3-4 days post-extraction)
Preventing Future Wisdom Tooth Infections
Prevention is always better than treatment when it comes to wisdom tooth infections. By maintaining excellent oral hygiene, attending regular dental checkups, and following your dentist’s recommendations, you can significantly reduce your risk of developing painful infections. Here are proven strategies to keep your wisdom teeth and entire mouth healthy.
Maintain Excellent Oral Hygiene
- Brush twice daily with fluoride toothpaste
- Floss daily, especially around back molars
- Use an antimicrobial mouthwash to reduce bacteria
- Consider a water flosser for hard-to-reach areas
Regular Dental Check-Ups
Schedule dental exams and cleanings every six months. Your dentist can monitor your wisdom teeth development and identify potential problems early through routine X-rays.
Consider Preventive Extraction
If your dentist recommends prophylactic wisdom tooth removal due to:
- Limited jaw space
- Impaction visible on X-rays
- History of dental problems with wisdom teeth
Consider having them removed before they cause problems. Preventive extraction is typically easier with faster recovery when done at a younger age before roots fully develop.
Lifestyle Factors
- Quit smoking, which significantly increases infection risk
- Maintain a balanced diet rich in vitamins and minerals
- Manage stress, which can impact immune function
- Stay hydrated to promote saliva production and natural mouth cleaning
When Is It a Dental Emergency?
Some wisdom tooth infection symptoms require immediate emergency dental care:
- Difficulty breathing or swallowing (indicates spreading infection)
- Severe facial swelling extending beyond the jaw
- High fever with chills
- Unbearable pain not relieved by medication
- Trismus so severe you cannot open your mouth
- Signs of sepsis (rapid heart rate, confusion, extreme fatigue)
These symptoms suggest the infection may be spreading to surrounding tissues, potentially causing or other life-threatening conditions requiring hospitalization.
The Importance of Professional Dental Care
While home remedies can provide temporary relief, they cannot cure an infected wisdom tooth. Only professional dental treatment can:
- Properly diagnose the extent of infection
- Prescribe appropriate antibiotics
- Remove the source of infection through extraction
- Prevent serious complications like bone infection (osteomyelitis) or systemic infection
Delaying treatment puts you at risk for:
- Infection spreading to other teeth or jaw
- Cyst or tumor formation around impacted teeth
- Damage to adjacent teeth and bone
- Severe complications requiring hospitalization
Conclusion
Wisdom tooth infections are painful and potentially dangerous, but they’re also highly treatable when caught early. If you’re experiencing symptoms like pain, swelling, bad taste, or difficulty opening your mouth, don’t wait — contact a dental professional immediately.

Frequently Asked Questions
How long does a wisdom tooth infection last?
With proper antibiotic treatment, symptoms typically improve within 2-3 days, though complete healing may take 1-2 weeks. Without treatment, the infection will persist and worsen.
Can a wisdom tooth infection go away on its own?
No. Wisdom tooth infections require professional treatment. The infection may temporarily seem better but will return and potentially worsen without proper dental care.
Is it safe to extract an infected wisdom tooth?
Yes, though dentists often prescribe antibiotics first to reduce active infection. In emergency situations, extraction may be performed despite infection to remove the source.
What happens if you ignore an infected wisdom tooth?
Ignoring the infection can lead to serious complications including abscess formation, bone infection, infection spreading to your jaw or neck, and even life-threatening sepsis.
How much does wisdom tooth extraction cost?
Costs vary based on complexity, ranging from $75-$200 for simple extractions to $225-$600+ for surgical extractions. Dental insurance typically covers a portion of the cost.
Can I eat normally with an infected wisdom tooth?
Stick to soft foods and avoid chewing on the affected side. Hard, crunchy, or sticky foods can worsen pain and introduce more bacteria to the infection site.
