Is a dull, steady ache throbbing in the back of your jaw? That pain could be more than just a minor annoyance—it might be a warning sign of an infected wisdom tooth. If you also have swelling around your jaw and red, tender gums, it’s time to pay attention.
What Is an Infected Wisdom Tooth?
Wisdom teeth, also known as third molars, are the last teeth to arrive. They usually appear in your late teens or early twenties. The problem is, our jaws often don't have enough room for them, which can lead to trouble.
An infected wisdom tooth happens when bacteria get into the gum tissue around a tooth that is stuck under the gum line (impacted) or has only partly broken through. Think of a partly emerged wisdom tooth like a door left slightly open. It creates a small pocket where food and bacteria can get trapped. This area is very hard to clean with brushing and flossing, making it a perfect spot for an infection to start.
This is a very common problem. According to the American Association of Oral and Maxillofacial Surgeons (AAOMS), about 9 out of 10 people have at least one impacted wisdom tooth. This bacterial buildup leads to painful swelling and the classic signs of infection. While some soreness is normal after wisdom tooth removal, an active infection is a different kind of pain. You can learn more about what to expect with pain in the jaw after wisdom teeth extraction in our other guide.
The 7 Most Common Signs of an Infected Wisdom Tooth
When a wisdom tooth gets infected, your body sends out warning signals. Catching these signs early is key to getting the care you need before a small problem gets bigger. While some discomfort is normal as wisdom teeth come in, the following signs usually point to an infection that needs a dentist's help.
The image below shows common signs like redness and swelling that often point to an infected wisdom tooth.
Even a little swelling around your jawline or redness in your gums can be a sign of a problem brewing under the surface.
1. Deep, Throbbing Pain
This isn’t your typical toothache. An infected wisdom tooth often causes a constant, pulsing pain deep in the back of your jaw. Sometimes, the pain can spread toward your ear or down your neck, making it hard to focus.
2. Swelling in Your Jaw or Cheek
An infection makes your body’s defense system kick in, causing inflammation. You might notice swelling in your cheek or jaw. You may even feel swollen lymph nodes under your jawline, which often feel tender and warm.
3. A Bad Taste or Smell That Won't Go Away
A strange taste or bad breath that lingers even after you brush is a classic sign of infection. This is usually caused by pus from the bacteria collecting in the gum tissue around the wisdom tooth.
Why This Happens: Imagine a small flap of gum covering a wisdom tooth that hasn't fully come in. This flap creates a tiny pocket that is hard to clean. Food bits and bacteria get trapped, creating the perfect spot for an infection that causes an unpleasant taste and smell.
4. Trouble Opening Your Mouth or Chewing
When the infection and swelling get worse, it can make your jaw muscles stiff and sore. This condition, called trismus, can make it painful to open your mouth wide, chew, or even swallow comfortably.
5. Red, Tender, or Bleeding Gums
Look at the gums around the problem tooth. They will likely look puffy, bright red, and feel sensitive to the touch. It’s also common for the area to bleed easily when you brush.
6. Visible Pus or Discharge
In more serious cases, you might see a yellowish or whitish fluid—pus—coming from the gumline near the tooth. This is a clear sign that your body is fighting a bacterial infection and an abscess may be forming.
7. Fever and Feeling Unwell
A dental infection can affect your whole body. If bacteria get into your bloodstream, you might develop a low-grade fever or feel tired and run down. This is your body telling you the infection could be spreading and you need to see a dental professional in Surprise, AZ right away.

Why Do Wisdom Teeth Get Infected?
Have you ever wondered why wisdom teeth cause so many problems? The main reason is simple: there’s not enough space in your jaw.
Think of your jaw like a parking lot and your teeth as cars. By the time your wisdom teeth try to arrive, the lot is usually full.
This crowding forces them to become impacted. This means they get stuck under the gums or grow in at an odd angle, pushing against other teeth. It’s a very common issue and the main cause of most wisdom tooth infections.
The Problem with Partial Eruption
Sometimes, a wisdom tooth only breaks partway through the gum. When this happens, it creates a small flap of gum tissue over the tooth. This condition, known as pericoronitis, is a major risk for infection.
That small gum flap creates a deep pocket that’s almost impossible to clean well. Food and bacteria get trapped, creating a warm, moist place for a painful infection to grow.
This buildup of bacteria is what causes all those unpleasant symptoms like pain and swelling. To better understand what’s happening, it helps to know the basic difference between bacteria and viruses and how they cause infections.
If left untreated, an infection in the gums can spread deeper into the tooth, possibly causing an abscess that needs more complex treatment. You can learn more about how we handle deep tooth infections in our guide to root canal therapy. Here at West Bell Dental Care, we help patients from Surprise, Peoria, and Sun City West understand these risks and find relief.
The Risks of Ignoring an Infected Wisdom Tooth
It’s tempting to hope that a nagging pain in your jaw will just go away on its own. But when it comes to an infected wisdom tooth, ignoring the signs can turn a small problem into a serious health issue.
Think of the infection like a small spark. If you don’t put it out, it can easily spread.
An untreated infection can lead to a dental abscess. This is a painful pocket of pus that forms deep in the gum or bone. This causes severe pain and requires more involved treatment to fix.
How the Infection Can Spread
When the bacteria from an infected wisdom tooth aren't treated, they can travel through your jaw and even into your bloodstream. This can cause a chain reaction of other problems.
The risks include:
- Damage to Other Teeth: The infection can spread to the tooth next door, causing decay or root damage.
- Jawbone Damage: A long-term infection can start to break down the bone that supports your teeth, which can weaken your entire jaw structure.
- Systemic Health Issues: It's not just about your mouth. A constant infection in your mouth can contribute to other health problems in your body.
Though very rare, a spreading oral infection can lead to life-threatening conditions. A historical example is Lemierre syndrome, a severe complication from bacterial infections, with an estimated incidence of only one in one million people worldwide. You can discover more insights about this rare condition here.
Getting timely care from a dentist in Surprise, AZ is the best way to keep a small issue from getting worse. Proper treatment not only relieves your pain but also protects your long-term health. If the tooth needs to be removed, it's also important to know what not to do after tooth extraction to ensure you heal properly.
How to Treat an Infected Wisdom Tooth
If you are dealing with a painful, infected wisdom tooth, the good news is that we can help. At West Bell Dental Care, our first step is to get you out of pain and treat the infection. We start with a dental exam and X-rays to see what’s going on under your gums.
Usually, our first goal is to control the immediate infection. This often means we will prescribe antibiotics to fight the bacteria causing the pain and swelling. We will also gently clean the area around the tooth to remove any trapped food, which often provides quick relief for our patients here in Surprise.
The Long-Term Solution: Wisdom Tooth Extraction
While antibiotics help with the immediate problem, they don’t fix the cause. If your wisdom tooth is impacted or only partly through the gum, it will likely get infected again. That's why the best permanent solution is usually wisdom tooth extraction.
We know that having a tooth removed can sound scary. But modern dentistry is very gentle, and we offer options to make the process comfortable and stress-free. We will talk you through every step so you feel relaxed and informed.
Think of an extraction as a final solution. It stops the cycle of pain and infection for good and protects your overall oral health.
This is an extremely common procedure. An estimated 5 million people in the U.S. have their wisdom teeth removed each year, which shows how often it’s the right choice. You can learn more about the prevalence of this procedure and why it's so common.
After the wisdom tooth is gone, we can talk about other options if you have missing teeth, such as dental implants in Surprise.
