How Long Until a Tooth Infection Kills You?Updated 3 days ago

A tooth infection might start as a small toothache, but if ignored, it can become very dangerous. While it doesn’t kill instantly, an untreated infection can spread quickly to other parts of the body and, in severe cases, become life-threatening.

A tooth infection doesn’t become deadly overnight, but if left untreated, it can spread beyond the tooth in just a few days to two weeks. In some severe cases, bacteria may enter the bloodstream within days, leading to life-threatening complications like sepsis.

How a Tooth Infection Develops

A tooth infection usually begins when bacteria enter the tooth through a cavity, crack, or gum disease. The body reacts by creating pus, which forms an abscess. At first, the infection is local (limited to the tooth), but without treatment, it can spread to the:

• Jawbone
• Neck and throat
• Bloodstream (causing sepsis)
• Brain or heart, in rare cases

Warning Signs of a Serious Infection

Seek medical or dental help immediately if you have:

• Severe, throbbing tooth pain
• Swelling in the face, jaw, or neck
• Difficulty swallowing or breathing
• High fever and chills
• Fatigue, confusion, or dizziness

Can It Be Treated?

Yes. Tooth infections are highly treatable if caught early. Dentists may:

• Drain the abscess
• Prescribe antibiotics
• Perform a root canal or tooth extraction
