Enlarged gum
An enlarged gum may result from plaque, irritation, medication effects, eruption, or a local growth and should be assessed if it persists.
The short answer
An enlarged gum is tissue that appears thicker, swollen, or overgrown around a tooth or across part of the mouth. Causes include local inflammation, a trapped tooth, medication-related change, or another lesion.
What can cause one area of gum to become enlarged?
Plaque makes gum tissue inflamed and puffy, while food trapping, a sharp restoration, or a partially erupted tooth can enlarge one site. Examination includes colour, bleeding, firmness, pockets, medicines, and the time course.
How can you clean an enlarged gum without causing injury?
Clean gently along the gumline and between teeth without cutting the tissue. Do not scrape, burn, or self-treat a persistent lump; note changes in size, colour, pain, and bleeding.
When should an enlarged gum be examined?
Book an examination when enlargement remains after cleaning, grows, bleeds, is painful, or interferes with eating. Rapidly spreading swelling, fever, or trouble breathing or swallowing needs urgent care.
What should you ask about the cause of an enlarged gum?
Ask what structure is enlarged and whether plaque, a tooth, medication, or a separate lesion explains it. Ask whether imaging or tissue sampling is indicated.
