What cause swelling of the gum
Gum swelling can result from plaque inflammation, food impaction, trauma, or an infection in a tooth or gum.
What commonly causes swelling in one area of the gum?
Gum swelling can result from plaque inflammation, food impaction, trauma, or an infection in a tooth or gum.
Why does inflammation make the gum red and enlarged?
The gingiva contains blood vessels and connective tissue, so inflammation makes it red, tender, and enlarged. Swelling beside one tooth can point to a local irritant, periodontal pocket, or dental abscess.
What can you do safely for a swollen gum?
Rinse gently with warm water, brush softly, and clean between the teeth without forcing an object into the gum. Do not apply aspirin, alcohol, or caustic chemicals directly to the tissue.
When does gum swelling need prompt dental care?
Seek care promptly for swelling that is painful, enlarging, draining, or accompanied by fever. Facial swelling or difficulty swallowing or breathing requires urgent help.
Which tests can identify the cause of gum swelling?
Ask whether the swelling is confined to the gum or connected to the tooth root, and whether probing, a vitality test, or an X-ray is needed.
Frequently asked questions
Can food cause gum swelling?
Yes. Food trapped between teeth can irritate the papilla, the small triangular gum area between them.
Does swelling always mean infection?
No. Irritation and plaque inflammation can swell the gum, although infection must be considered when pain or drainage is present.
