A dental abscess is a bacterial infection that creates a collection of pus inside or around a tooth. It can cause severe pain and swelling, so it requires urgent dental attention.
A dental abscess often develops when bacteria enter the inner part of a tooth or the tissues around it. Deep decay, a cracked tooth, gum disease, or failing dental work can create a pathway for infection.
A dental abscess is unlikely to go away without professional treatment. Without care, the infection may spread to the jaw, face, or neck and lead to more serious complications. Seeing a dentist as soon as possible can relieve discomfort, control the infection, and give the affected tooth the best chance of being saved.
Important Note: This article provides general information only. It is not a substitute for an in-person examination, diagnosis, or treatment plan from a qualified dental professional. Please seek immediate medical care if you notice symptoms of a dental abscess.
What is Dental Abscess
A dental abscess is a build-up of pus caused by a bacterial infection. It can form inside a tooth, around its root, or in the gums and supporting tissues.
A dental abscess may appear as pus around a tooth or beneath the gum. Pus develops as the body reacts to bacteria in the affected area. As pressure increases, the tooth or gum can become painful, swollen, red, or tender. Some abscesses cause a small bump on the gum, while others lead to deep pain with little visible swelling.
Stages of Dental Abscess
Stages of a Dental Abscess
A dental abscess does not always follow the same pattern, but it often develops in the following stages.
Bacteria Enter the Tooth or Gums
A cavity, crack, fracture, leaking filling, damaged crown, or gum disease can allow bacteria to reach deeper tissues.
Inflammation Begins
When bacteria reach the pulp inside the tooth or the surrounding tissues, the body reacts with inflammation. You may notice sensitivity to hot or cold foods, pain when biting, or an ongoing toothache.
Pus Forms
As the infection worsens, a pocket of pus may develop near the tooth root or within the gum tissue. This can cause throbbing pain, swelling, redness, or a visible lump on the gum.
The Infection Can Spread
Without treatment, a dental abscess can spread into nearby tissues. Facial swelling, fever, or difficulty opening the mouth may follow. In some cases, the infection can lead to serious complications.
Early dental treatment can control the infection before it causes further damage or requires more complex care.
Types of Tooth Abscess
Dental abscesses are commonly classified according to where the infection develops.
| Type | Where It Develops | Description |
| Periapical abscess | At the tip of a tooth root | Often called a tooth root abscess or abscess under tooth |
| Periodontal abscess | In the tissues surrounding a tooth, often within a deep gum pocket | Described as an abscess around the tooth |
| Gingival abscess | In the gum tissue itself | Often called a gum abscess |
| Pericoronal abscess | In the gum tissue around a partially erupted tooth | May occur when food and bacteria become trapped beneath the gum |
How Serious is Dental Abscess
A dental abscess can be serious because the infection may continue to spread if the underlying cause is not treated.
Dental abscess pain can range from a mild ache to severe, throbbing pain that affects sleep, eating, speaking, and normal daily activities. Pain may spread to the jaw, ear, neck, or side of the face.
An abscessed tooth can also lead to swelling of the gums, cheek, jaw, or face. In some cases, the infection may spread into deeper spaces in the face or neck. This is why a suspected abscess should be assessed by a dentist as soon as possible.
Pain suddenly improving does not always mean the problem has healed. An abscess may drain and reduce pressure, but bacteria can still remain inside the tooth or surrounding tissues.
What Triggers a Tooth Abscess
A tooth abscess can develop when bacteria enter the deeper layers of a tooth or move below the gum line. Common causes include:
- Untreated decay or a deep cavity
- A chipped, cracked, broken, or worn tooth
- A damaged filling or crown
- Gum disease that creates deep pockets around the teeth
- Food and bacteria trapped around a partially erupted wisdom tooth
- Dental trauma that affects the inside of a tooth
- Delayed treatment for an existing dental problem
- Poor oral hygiene, which allows plaque, decay, and gum disease to worsen
Prevention is important. A cavity, broken tooth, loose filling, damaged crown, or ongoing gum swelling should be assessed by a dentist before bacteria can reach the deeper tissues.
Regular dental check-ups can help identify decay, gum disease, cracks, and damaged restorations before they become painful or develop into an infection.
What are Dental Abscess Symptoms
Symptoms can vary depending on the type and severity of the infection. Common dental abscess symptoms include:
- Severe or throbbing toothache
- Pain when chewing or touching the tooth
- Sensitivity to hot, cold, or sweet foods and drinks
- Swollen or red gums
- A small lump or swelling on the gum
- Swelling in the cheek, jaw, face, or neck
- A bad taste in the mouth if the abscess drains
- Bad breath
- Fever or feeling generally unwell
Do not wait for symptoms to disappear. A dental abscess needs professional assessment, even if the pain becomes less noticeable or the swelling appears to reduce.
Treatment of Dental Abscess
The most suitable treatment depends on the location of the abscess and whether the affected tooth can be saved. A dentist may recommend one or more of the following:
- Draining the abscess: Releasing trapped pus can reduce swelling, pressure, and pain.
- Root canal treatment: If the infection is inside the tooth, root canal treatment may remove the infected tissue, clean the tooth from within, and allow the tooth to be restored.
- Gum treatment: When the infection is related to gum disease, the area may need professional cleaning and treatment for the underlying gum condition.
- Tooth extraction: If the tooth is too severely damaged or cannot be restored safely, removal may be the best option to eliminate the source of infection.
- Antibiotics when needed: A dentist may prescribe antibiotics when infection is spreading, when there is fever or general illness, or when there is a higher risk of complications. Antibiotics alone do not remove the cause of most dental abscesses.
After the infection is controlled, the dentist may discuss how to restore the tooth or replace it if extraction was necessary. The restoration process can include a crown after root canal treatment or a replacement option such as dental implants.
Can a Dental Abscess Heal on its Own?
No. A dental abscess should not be expected to heal on its own.
The abscess may burst or drain, which can temporarily reduce pressure and pain. However, the infection may still be present inside the tooth, root, gums, or jawbone. Without treatment, it can return, worsen, or spread.
The safest approach is to seek professional treatment immediately when symptoms first appear. Timely treatment can relieve pain and prevent possible complications, it can also help save the affected tooth.
