Dental question about taxonomy:condition:dental-abscess
A dental abscess is a pocket of pus from bacterial infection in a tooth or nearby gum and needs prompt dental treatment.
The short answer
A dental abscess is a pocket of pus from bacterial infection in a tooth or nearby gum and needs prompt dental treatment. Treatment may involve draining pus, removing infected tissue with root canal treatment, or removing the tooth when it cannot be restored.
How do periapical and periodontal abscesses differ in location?
A periapical abscess starts near the root tip when infection travels through the pulp, while a periodontal abscess starts in the gum and supporting tissues. Swelling may form a gum boil, but the visible bump does not show how far infection has spread.
What should you do while arranging prompt care for an abscess?
Arrange prompt dental assessment and use only pain relief that is suitable for your health and medicines. Do not squeeze the swelling, pierce it, place aspirin on the gum, or use leftover antibiotics; the source of infection still needs dental treatment.
When does toothache with swelling require urgent dental care?
Seek urgent dental care for toothache with swelling, pus, fever, or a bad taste. Go to emergency services for swelling that affects the eye or neck, or for difficulty breathing, swallowing, or opening the mouth.
What should you ask about removing the source of an abscess?
Ask where the abscess began, whether a radiograph is needed, and whether drainage, root canal treatment, extraction, or gum treatment will remove the source. Ask what warning signs mean the infection is spreading.
Frequently asked questions
Can an abscess disappear by itself?
Pain or swelling can change, but the infected source remains until dental treatment addresses it.
Will antibiotics cure the tooth?
Antibiotics may be used in selected spreading or systemic infections, but they do not replace treatment of the infected tooth or gum.
