Your oral health is critical for your smile as well as your overall health and well-being. One of the biggest dental concerns that can have the most impact on daily life is a dental abscess. This condition is painful and can be potentially serious.

Dr. Arianna Rodriguez and the team at Delight Dental Smiles understand how to diagnose and treat dental abscesses. A dental abscess is more than just a toothache; it is a localized collection of pus that forms within the teeth or gums, stemming from a bacterial infection. If left untreated, this dental concern can be fatal.

Understanding the intricacies of dental abscesses—from their types and signs to causes, prevention, and potential risks—is paramount for individuals seeking to prioritize their oral health and overall quality of life.

This article explains what you need to know about this dental issue.

What is a Dental Abscess?

A dental abscess is a localized collection of pus that forms within the teeth or gums, often as a result of a bacterial infection. This painful condition can lead to severe complications if left untreated. Understanding the types of dental abscesses is crucial for effective management.

Types of Dental Abscess

There are two primary types of dental abscesses: periapical and periodontal.

Periapical Abscess

This type of abscess originates at the tip of the tooth’s root and is commonly associated with untreated tooth decay or dental trauma.

Periodontal Abscess

Periodontal abscesses occur in the supporting structures of the teeth, such as the gums and bones. Poor oral hygiene and gum disease are common culprits for periodontal abscesses.

What are the Signs and Symptoms of a Dental Abscess?

Learning to recognize the signs and symptoms of a dental abscess is critical for early intervention. If left untreated, a dental abscess can spread to other areas of your body including your heart and brain.

The most common signs and symptoms of a dental abscess include:

  • Severe toothache
  • Swelling of the face/cheek
  • Sensitivity to hot/cold foods and beverages
  • Pain when biting or chewing
  • A pimple-like bump on the gums
  • Foul taste
  • Bad breath

If you notice any of these, it’s important to contact a dentist for treatment immediately to prevent escalation.

What Causes a Dental Abscess?

A dental abscess is typically the result of a bacterial infection. The most common causes of dental abscess include:

Untreated Tooth Decay

A cavity occurs when bacteria in the mouth produce acids that erode tooth enamel. If left untreated, the decay will progress deeper into the tooth, ultimately reaching the dental pulp where the nerves and blood vessels are located. This creates an environment for infection to develop.

Periodontal Disease

Periodontal disease, commonly referred to as gum disease, is characterized by inflammation and infection of the gums and supporting structures. As this condition advances, pockets form between the teeth and gums, creating a space for infection to develop.

Dental Trauma

Injuries to the teeth create openings for bacteria to get into the tooth and cause an infection. Even if the damage is not immediately obvious, the internal structures of the tooth can be compromised, leading to an abscess formation.

Failed Dental Procedures

In some cases, procedures such as dental fillings or root canal treatment may not eliminate bacteria. If bacteria is left behind, it can multiply which leads to an infection and the formation of an abscess.

Weakened Immune System

Patients with a weakened immune system are at a higher risk of developing a bacterial infection that can lead to abscess formation. Some of the most common conditions that increase this risk include HIV/AIDS, uncontrolled diabetes, and other immunodeficiency disorders.

Poor Oral Hygiene  

Inadequate oral hygiene practices can lead to the accumulation of plaque on the teeth and gums. Over time, this can lead to tooth decay and/or gum disease, both of which can potentially lead to the formation of a dental abscess.

How to Prevent Dental Abscess Formation

There are several things you can do to reduce your risk of developing a dental abscess:

Regular Check-UpsDental Abscess

According to the American Dental Association, everyone should be visiting the dentist every 6 months. These routine exams allow for the early diagnosis and treatment of dental issues, which significantly reduces the risk of abscess formation.


Proper oral hygiene, including brushing twice daily and flossing at least once, can effectively remove plaque and bacteria. This reduces your risk of developing a dental abscess.

Prompt Treatment of Dental Issues

If an issue comes up between dental check-ups, it’s important to seek immediate treatment. When left untreated, dental issues can lead to the formation of a dental abscess, but when treated promptly, your risk of significant issues is reduced.

What Happens if an Abscess is Left Untreated?

If left untreated, a dental abscess can lead to severe complications, including:

  • Spread of infection: the infection may spread to other areas of the body including the bloodstream, ultimately reaching the heart and/or the brain.
  • Tooth loss: the infection could cause irreversible damage to the tooth, which could require extraction
  • Abscess rupture: if the abscess ruptures, the pus may be released to surrounding tissues, leading to further complications
