Alternative Names

Periapical abscess; Dental abscess; Tooth infection; Abscessed tooth, tooth abscess, pus in the gums/mouth.


A tooth abscess is a complication of tooth decay. It may also result from trauma to the tooth, such as when a tooth is broken or chipped. Openings in the tooth enamel allow bacteria to infect the centre of the tooth (the pulp). Infection may spread out from the root of the tooth and to the bones supporting the tooth.

Infection results in a collection of pus (dead tissue, live and dead bacteria, white blood cells) and swelling of the tissues within the tooth. This causes a painful toothache. If the pulp of the tooth dies, the toothache may stop, unless an abscess develops. This is especially true if the infection remains active and continues to spread and destroy tissue.


The main symptom is a severe toothache. The pain is continuous and may be described as gnawing, sharp, shooting, or throbbing.

Other symptoms may include:

  1. Bitter taste in the mouth
  2. Breath odour
  3. General discomfort,
  4. uneasiness or ill feeling
  5. Fever
  6. Pain when chewing
  7. Sensitivity of the teeth to hot or cold
  8. Swelling of the gum over the infected tooth, that may look like a pimple
  9. Swollen Glands of the neck
  10. Swollen area of the upper or lower jaw — a very serious symptom

Exams and Tests

The dentist will closely look at your teeth, mouth, and gums. You may have pain when the dentist taps the tooth. Biting or closing the mouth tightly also increases the pain. The gums may be swollen and red and may drain thick material.

Dental x-rays and other tests can help your dentist determine which tooth or teeth is causing the problem.


1.The goals of treatment are to cure the infection, save the tooth, and prevent complications.

2.Antibiotics may be given to fight the infection. Warm salt-water rinses may be soothing. Over-the-counter pain relievers may relieve the toothache and fever.

3.Do NOT place aspirin directly over the tooth or gums, because this increases irritation of the tissues and can result in Mouth ulcers.

4.A root canal may be recommended in an attempt to save the tooth.

5.If there is a severe infection, the tooth may be removed or surgery may be needed to drain the abscess. Some people may need to be admitted to the hospital.

Outlook (Prognosis)

1.Untreated abscesses may get worse and can lead to life-threatening complications.

2.Prompt treatment usually cures the infection. The tooth can usually be saved in many cases.

Possible Complications

  • Loss of the tooth
  • Blood infection (sepsis)
  • Spread of infection to soft tissue (facial cellulitis, Ludwig’s angina)
  • Spread of infection to the jaw bone (osteomyelitis of the jaw)
  • Spread of infection to other areas of the body resulting in brain abscess,
  • endocarditis,
  • pneumonia, or other complications

How to ease the pain caused by a dental abscess?

Suffering from a dental abscess can be incredibly painful and distressing. The throbbing agony, swelling, and general discomfort can disrupt your life. There are several dental procedures that can help you ease the pain and address the underlying issue.

Dental Abscess Drainage

One of the most direct methods to relieve the pain associated with a dental abscess is to drain it. During this procedure, a dentist creates a small incision in the abscess to release the accumulated pus. This process provides immediate pain relief and helps prevent the infection from spreading. It is a precise procedure performed under sterile conditions.

Root Canal Therapy

If the dental abscess is related to an infection within the tooth, a root canal procedure may be recommended. During a root canal, the infected pulp is removed, and the tooth is thoroughly cleaned, disinfected, and sealed. This not only eliminates the pain but also preserves the tooth’s structural integrity, preventing the need for extraction.


In some cases, antibiotics are prescribed to control the infection associated with a dental abscess. These medications are used in conjunction with other dental procedures to address the root cause of the issue, ensuring a comprehensive treatment approach.

Tooth Extraction

In severe cases where the tooth is extensively damaged and cannot be saved, tooth extraction may be necessary. This procedure is performed with precision to minimize discomfort during and after the extraction. Afterward, replacement options, such as dental implants or bridges, can be discussed to restore your smile.

Pain Management

Effective pain management is a crucial aspect of dental abscess treatment. Dentists often use local anesthesia during procedures to minimize discomfort. Post-procedure pain relief measures are also discussed to ensure a smooth and comfortable recovery.

Preventative Care

Once your dental abscess has been treated, it’s important to maintain proper oral hygiene and attend regular check-ups to prevent future dental abscesses and other oral health issues.
