What Happens If a Tooth Abscess Goes Untreated?

Are the symptoms of a tooth abscess improving? Learn why untreated abscesses remain dangerous and what treatment options are available for anxious patients.

A tooth abscess can be frightening—not just because of the pain, but because many people sense that something is seriously wrong. For patients with dental anxiety, past trauma, or difficulty tolerating dental visits, it’s also common to delay care and hope the problem will somehow resolve on its own.

What Is a Tooth Abscess?

A tooth abscess is a pocket of infection caused by bacteria. It usually develops when bacteria enter the tooth or gums and the body tries to contain the infection. There are two common types:

  • Periapical abscess – begins inside the tooth, often after untreated decay or trauma
  • Periodontal abscess – begins in the gums or bone supporting the tooth

In both cases, the abscess contains bacteria, pus, and inflammatory material. It is not just inflammation or irritation—it is an active infection.

Common Symptoms of a Tooth Abscess

Symptoms can vary widely. Some abscesses are extremely painful, while others cause surprisingly little discomfort at first. Common signs include:

  • Persistent or throbbing tooth pain
  • Sensitivity to hot or cold
  • Swelling of the gums, face, or jaw
  • A pimple-like bump on the gums
  • Bad taste or odor in the mouth
  • Pain when biting or chewing
  • Fever or general feeling of being unwell

Importantly, pain may come and go, giving the false impression that the problem is improving.

Can a Tooth Abscess Go Away on Its Own?

No. A tooth abscess does not resolve without treatment. While pain or swelling may temporarily decrease if the abscess drains, the infection itself remains. The bacteria continue to live inside the tooth, bone, or gum tissue and can spread over time.

Antibiotics alone do not cure a tooth abscess. They may temporarily reduce symptoms, but without addressing the source of infection, the abscess almost always recurs.

What Happens If a Tooth Abscess Is Left Untreated?

Leaving a tooth abscess untreated allows the infection to progress. What happens next depends on the individual, the location of the abscess, and overall health—but the risks increase with time.

How Tooth Abscesses Are Treated

Treatment focuses on eliminating the source of infection, not just relieving symptoms.

Depending on the situation, treatment may involve:

For patients who cannot tolerate dental treatment while awake, these procedures can often be completed under sedation or dental anesthesia, allowing care to happen without pain, panic, or traumatic memories.

A tooth abscess is a serious infection that does not heal on its own. While fear or avoidance is understandable, delaying care allows the problem to grow and limits future options. The good news is that there are ways to treat abscesses comfortably and safely, even if traditional dental visits feel overwhelming or impossible. A consultation doesn’t mean committing to treatment—it simply means understanding your options, your risks, and the safest next step.
