Can You Die From A Tooth Infection?

Is it possible to die from a tooth infection? Hypothetically speaking, is there a timeframe for how long until a tooth infection kills you or puts you in the hospital? The answer might not be as simple as you think, but severe tooth infections can definitely be life-threatening. 

Depending on how technical or knit-picky you want to get about the science behind it, yes, you can die from a tooth infection. Although by the time an infection reaches that severe of a level, it’s not just isolated inside of your tooth. It starts in your tooth but by the point it becomes fatal, there’s a lot more going on. All that being said, don’t ignore that cavity or a tooth abscess your dentist points out on your X-ray.

Can A Tooth Infection Kill You?

How is it that a tooth infection can actually kill you? Well, when you consider that bacteria from severe periodontal disease can spread straight into your bloodstream, lungs, or brain, the concept isn’t as far-fetched as it sounds.

An infected tooth can kill you by allowing bacteria to spread elsewhere in your body. Especially your brain and bloodstream. 

Let’s say for a moment that you have an abscessed tooth. These teeth have cysts around the root that are filled with bad bacteria. Slowly but surely, this cyst or tooth abscess will start to invade the bone structures and soft tissues next to the tooth. It could easily spread into your bloodstream, nasal sinuses, nerves, face, and yes, your brain. 

Gum infections aren’t all that different. Even though there’s no tooth abscess there, you do have severe inflammation, bleeding, and colonies of bacteria living below the surface of your gum tissues. 

Here are several life-threatening situations that can tie back to a toothache and why you shouldn’t skip out on that recommended dental work:

1. Sepsis: 

Sepsis is a life-threatening condition where your body is overwhelmed with some type of bacterial infection. It can cause both tissue damage and organ failure, destroying otherwise healthy tissues inside your body. If your tooth abscess drains into an area like your sinus cavity or bloodstream, it can lead to sepsis, and sepsis can often be fatal.

2. Ludwig’s Angina: 

Ludwig’s angina is a type of infection that occurs in the floor of your mouth, involving areas like your neck and jaw. It’s a type of “cellulitis.” This dangerous infection is most often caused by oral infections (like infected teeth) or a traumatic injury to the jaw. It’s frequently seen in children. Typically it needs to be treated by draining the abscess and a round of antibiotics, but it can occasionally be fatal.

3. Necrotizing Fasciitis:  

This rare infection is fast-spreading and is caused by bacteria. It results in the decay of the fascia inside of soft tissues. And yes, it’s fatal. Symptoms include pain, swelling, fever, ulcers and blisters, and fatigue, among others.

4. Endocarditis:

Endocarditis is where the heart becomes inflamed because of a bacterial infection or some type of fungi. And yes, it’s deadly. Can you get endocarditis from a tooth infection? Yes. In fact, health experts recommend that people who are at risk for infective endocarditis be especially good about their oral hygiene habits to prevent tooth abscesses or gum infections from spreading into their bloodstream.

5. Cavernous Sinus Thrombosis:

When you get a blood clot inside of the “cavernous sinuses” (like the hollow nasal sinuses above your teeth but below your brain and eye socket) it can be deadly. Since your tooth roots lie just alongside of some of your sinus cavities, you have to be especially careful about not allowing abscessed teeth to spread infection into those areas. 

6. Osteomyelitis:

Osteomyelitis is a type of bone infection. It spreads into the bone from the bloodstream or from an infection right next to the bony structure, like an abscessed tooth. It causes painful swelling inside your bone marrow. People with diabetes, young children, and the elderly are most at risk.

7. Brain Abscess:

Can you get a brain abscess from a tooth infection? Yes. When you do, it’s called an odontogenic brain abscess. This deadly condition may be due to undiagnosed cavities or other dental infections. Death or a permanent handicap are common side effects of brain abscesses.

How Long Until A Tooth Infection Kills You?

A severe dental infection should never be treated lightly. Trying to figure out how long until a tooth infection kills you doesn’t mean you can buy time by putting off dental treatment. There are cases where symptoms may come on suddenly, or a patient may go months with a dental infection before developing life-threatening ailments. Like other deadly infections and diseases, problems may come on quicker than you expect. And by the point they become severe or life-threatening, your treatment options are more limited.

In reality, a person can die within days or weeks of a tooth infection spreading into their bloodstream. And since the severity of a dental infection isn’t easy to measure on your own without diagnostic X-rays, it’s extremely important to listen to your dentist’s recommendations when it comes to active dental disease. If you don’t trust your dentist or it seems like they’re recommending a treatment you don’t need, always, always, always get a second opinion. It just isn’t worth the risk of overlooking a potentially fatal tooth infection. 

All of that being said, you’re most likely not going to die within a week of a small cavity being diagnosed. Why? Because tooth decay goes through various stages. Such as:

1. Enamel Decay

This is where the cavity is isolated in the outer layer of the tooth structure. A dental filling is usually all that’s needed. 

2. Dentin Decay 

Once the tooth decay has ruptured through the enamel, it enters into the softer dentin layer underneath. It can grow much more quickly at this point. Larger dental fillings are required. Or sometimes inlays, onlays, or crowns.

3. Pulp Decay

The tooth decay has reached the nerve tissue inside the tooth. At this point, root canal therapy is a must.

4. Dental Abscess Formation

A fluid-filled cyst develops around the tip of the tooth root. There may be a visible blister or pocket of pus on the gums. The cyst is visible inside the bone when an X-ray is taken. A root canal or extraction are imminent. 

5. Serious Complications

Untreated abscessed teeth where the cyst spreads into the surrounding bone, sinuses, and blood vessels. 

Symptoms of a Tooth Infection Spreading to the Body

In most cases, severe tooth infections are either related to an abscessed tooth or advanced periodontal disease. In both scenarios, redness and swelling of the mouth are extremely common. However, if the tooth infection has spread elsewhere in the face, you may notice a swollen cheek, jaw, eyes, throbbing pain or difficulty breathing due to an obstructed airway. Fatigue and fever are also common. In some cases, symptoms also include neck pain, nausea, and vomiting. 

When a dental infection spreads elsewhere, it’s easy to mistake the issue for something more generalized as opposed to your tooth. Because of the close proximity of dental infections with the airway and brain, doctors may order a CT scan to determine the location of where the infected source originates. 

Should You Go To The Hospital? 

Most tooth infections need to be treated promptly by a dentist. But if it’s severe, you need to understand that there’s a risk of knowing how long until a tooth infection kills you. You should go straight to the hospital emergency room if you are experiencing facial swelling, difficulty breathing, a high fever, or such significant physical symptoms that it’s obvious there is a medical emergency going on. If you know that you or your child already has an abscessed tooth and they are suddenly lethargic or vomiting uncontrollably, emergency medical treatment is a must.

Who Is An Increased Risk For a Tooth Abscess?

Even though anyone can theoretically die from a tooth infection, there are certain individuals who are at a higher risk of fatal side-effects. Such as:

Young children

Individuals with diabetes

Elderly

People who are immunocompromised

If you have an immune disease or are more susceptible to illnesses, a severe dental infection can potentially be life-threatening if allowed to go untreated. 

How To Treat Infected Teeth?

Most infected teeth can be treated through procedures such as:

Dental fillings

Crowns

Pulpotomies or pulp capping

Root canal therapy/endodontics

Surgical extractions

Antibiotics as part of your restorative/therapeutic procedure

Deep Cleanings (Periodontal therapy)

Dental infections cannot be treated with antibiotics alone. However, if your infected tooth is severe, your dentist may prescribe antibiotics in conjunction with other procedures to reduce the overall bacterial load inside your body leading up to the treatment. Antibiotics will also help with making your planned procedure more comfortable, as severe infection and swelling can interfere with how effective dental numbing medications (local anesthetic) are during your procedure. 

How To Prevent Tooth Infections

The best way to prevent fatal tooth infections is to see your dentist routinely for checkups and cleanings and to treat infected teeth as soon as conditions are diagnosed. Do not wait for a tooth to start hurting before you have it treated. It is not uncommon for cavities to evolve into abscessed teeth without any painful symptoms being present. If a dental abscess is left untreated, it can spread into the head and neck causing serious complications. If you have second thoughts about your dentist’s recommendations for treatment, seek out a second opinion rather than “tough it out” before you see the infection for yourself.
