What does “Gingival abscess” mean?
A gingival abscess is a localized collection of pus in relatively superficial gum tissue, such as the gum margin or gum between teeth. It must be distinguished from a periodontal abscess in a deep pocket or infection at a tooth root tip.
Acute inflammation confined to the gum
Trapped food or foreign material can cause a swollen, painful lesion. Even if it looks like a small bump, surface appearance alone does not reveal where the infection began. Periodontal condition and tooth pain are assessed together to distinguish a deeper lesion draining through the gum.
What is checked at the clinic
Swelling location and onset, pocket depth, and foreign material are checked, with pulp tests and radiographs when needed. The need to remove a local cause and drain the abscess is assessed. Avoid piercing it with a needle or squeezing pus out by hand at home because of injury and infection risks.
Why treatment differs from a periodontal abscess
A gingival abscess is confined to the gum, while a periodontal abscess may involve deeper supporting tissues. Antibiotics alone do not remove the cause; their use depends on spreading infection or systemic symptoms. Facial swelling, fever, or difficulty swallowing or breathing requires immediate care.
Frequently Asked Questions
Does a small collection of pus in the gum need dental care?
Even a small lesion needs assessment of its cause and depth. A foreign body or tooth or periodontal infection may remain even if drainage reduces pain.
Does a gingival abscess require root canal treatment?
First distinguish whether the infection originated in the pulp. Root canal treatment is not selected solely because a lesion is present in the gum.
