Warning Signs of Sepsis from a Tooth Infection

Dental infections may seem minor at first, but when bacteria spread, they can lead to a serious condition called sepsis. If you've got a lingering toothache or swelling, the quick answer is: yes, an untreated tooth infection can potentially lead to sepsis—and fast. Recognizing the early signs could protect your health, or even save your life.

What Is Sepsis from a Tooth Infection?

Sepsis happens when the body has an extreme response to infection. When bacteria from an abscessed or infected tooth enter the bloodstream, they can trigger this reaction.

According to the CDC, sepsis is responsible for 1 in 3 hospital deaths in the U.S. While sepsis from a dental infection is rare, it’s not unheard of—and it's a medical emergency.

Symptoms of Sepsis Originating from a Tooth Infection

Here are the warning signs to watch for:

• High fever or chills
• Rapid heart rate or breathing
• Confusion or disorientation
• Extreme pain or discomfort
• Facial swelling that spreads to the neck or jaw
• Persistent pus, bad taste, or foul breath

Dr. Bruce Yaffe, a New York-based internal medicine expert, warns: “Once the infection spreads beyond the tooth, it becomes a systemic issue. Time is of the essence.”

If you're noticing any of the above symptoms along with a dental issue, don’t delay. Early treatment can prevent complications like sepsis and preserve your overall health.
