Periodontal Abscess: What to Do
A periodontal abscess is a pocket of pus beside a tooth linked to infected gum tissue. Learn why prompt dental treatment matters.
The short answer
A periodontal abscess is a localized collection of pus in the gum beside a tooth and needs prompt dental assessment for drainage and treatment of the underlying gum or tooth problem.
How does an abscess develop beside a tooth?
The abscess forms in the periodontal tissues that attach and support the tooth, often when bacteria enter a deep gum pocket or drainage is blocked. It can cause a tender swelling, bleeding, bad taste, tooth looseness, or pain when biting.
What can you do while waiting for dental treatment?
Keep the area clean with gentle brushing and rinse with warm salt water, but do not squeeze or pierce the swelling. A dentist may examine gum pockets, test the tooth, take dental radiographs, drain pus, clean the pocket, and treat the tooth if its pulp is involved.
How quickly should swelling from an abscess be assessed?
Contact a dentist promptly rather than waiting for the swelling to burst. Go to urgent medical care if swelling spreads into the face or neck, or if fever, weakness, difficulty opening the mouth, swallowing, or breathing develops.
What treatment might be needed for the abscess?
Ask whether the infection is in the gum or tooth, whether drainage is needed, how the pocket will be cleaned, and whether periodontal treatment, root canal treatment, or extraction is indicated.
Frequently asked questions
Can a gum abscess heal by itself?
The pressure may reduce if it drains, but the infected pocket or tooth still needs assessment and treatment.
Is a periodontal abscess the same as a tooth abscess?
No. A periodontal abscess starts in supporting gum tissues, while a tooth abscess starts from infected pulp or tissues around the root.
