Can You Get Sepsis From an Infected Tooth?

An infected tooth can lead to sepsis, a serious and potentially life-threatening condition. While a tooth infection might seem like a localized problem, bacteria can spread beyond the mouth.

What is a Tooth Infection?

A tooth infection, or dental abscess, is a pocket of pus caused by a bacterial infection. This infection typically forms at the root tip (periapical abscess) or in the gums beside the tooth (periodontal abscess). Untreated cavities, cracked teeth, or dental trauma allow bacteria to invade the tooth’s pulp.

As bacteria multiply, they trigger an inflammatory response, leading to pus. Common local symptoms include severe, throbbing pain that can radiate to the jaw, ear, or neck, and sensitivity to hot or cold temperatures. Swelling in the gums, face, or jaw, along with a foul taste or bad breath, can also indicate infection. These infections require professional dental treatment.

Understanding Sepsis

Sepsis is a life-threatening medical emergency resulting from the body’s extreme response to an infection. Instead of effectively fighting the infection, the immune system overreacts, causing widespread inflammation. This dysregulated response can damage the body’s own tissues and organs, leading to dysfunction or failure.

Sepsis can arise from any type of infection, including bacterial, viral, fungal, or parasitic. Without prompt treatment, it can rapidly progress, leading to organ damage or death.

The Link: How a Tooth Infection Can Lead to Sepsis

Bacteria from an untreated tooth infection can spread beyond the localized area and enter the bloodstream. This occurs when the infection erodes surrounding tissues, providing a pathway for bacteria to escape. Once in the bloodstream, these bacteria can travel to other parts of the body.

The body’s immune system detects these circulating bacteria, triggering a systemic inflammatory response. In some individuals, this response becomes dysregulated, meaning the immune system’s reaction is too strong or uncontrolled. This uncontrolled inflammation can then harm the body’s own organs and tissues, leading to sepsis.

Factors that increase the risk of a tooth infection progressing to sepsis include delayed treatment. Individuals with weakened immune systems, such as those with chronic illnesses like diabetes or HIV, or those undergoing chemotherapy, are also more susceptible. The severity and location of the dental abscess can also influence bacterial spread.

Recognizing Sepsis Symptoms and Seeking Care

Recognizing the signs of sepsis is important for timely medical intervention. While a tooth infection causes localized pain and swelling, sepsis symptoms are systemic. Key indicators of sepsis include:

Persistent fever or unusually low body temperature
Chills
Rapid heart rate
Rapid breathing or shortness of breath
Confusion or disorientation
Clammy or sweaty skin
Extreme pain or discomfort
Decreased urine output

If these symptoms appear, especially with a known tooth infection, seek immediate medical attention. Prompt dental care for any tooth infection is important to prevent its escalation and reduce the risk of systemic complications like sepsis. Ignoring tooth pain or swelling can allow the infection to spread, increasing the potential for serious health issues.
