Gum swelling causes symptoms and treatment
Swollen gums may reflect plaque inflammation, trapped food, trauma, medication effects, or infection around a tooth.
The short answer
Gum swelling is enlargement of gingival tissue caused by inflammation, irritation, or infection, and treatment depends on the location, duration, and signs around the affected tooth.
Why can plaque, trapped food, or sharp edges swell gums?
Gingiva can swell when plaque irritates the gum margin, food is trapped, or a sharp edge causes trauma. A localized lump may be related to an abscess from the pulp or periodontal tissues, while generalized swelling has broader causes.
What can you do at home for swollen gums?
Brush softly along the gumline, clean between teeth, and rinse with plain water after meals. Do not squeeze a lump or apply caustic substances; arrange an examination so the tooth, gums, pockets, and bite can be assessed.
Which gum swelling symptoms require urgent care?
Seek urgent care for rapidly increasing swelling, facial swelling, fever, pus, difficulty swallowing or breathing, or trouble opening the mouth. Persistent or recurrent swelling also needs dental diagnosis.
Where exactly is the swelling located in your mouth?
Is the swelling at the gum edge, beside one tooth, or throughout the mouth? Is there bleeding, pus, pain to biting, a deep pocket, or a damaged filling? Does the tooth need drainage, periodontal care, or restoration?
Frequently asked questions
Can swollen gums go down by themselves?
Mild irritation may improve when plaque or trapped food is removed, but a recurring lump or painful swelling needs diagnosis.
Does a swollen gum always mean an infection?
No. Irritation, trauma, medication effects, and other conditions can also enlarge gum tissue.
