Why do i have a sore on my gums

A sore on the gums can result from trauma, an aphthous ulcer, infection, irritation, or a draining tooth abscess, so its appearance and duration matter.

A gum sore may be a shallow ulcer from biting, a sharp tooth, a toothbrush injury, or an aphthous ulcer. A pimple-like swelling that drains near a tooth can instead be a sinus tract from infection inside the tooth.

Other possibilities include viral lesions, periodontal inflammation, a poorly fitting appliance, or a persistent lesion that needs specialist assessment.

Rinse gently with water or a mild salt-water solution, use a soft brush, choose foods that do not irritate it, and avoid tobacco and caustic products. Do not pop a swelling or place aspirin on the tissue.

Note the size, colour, exact site, pain, triggers, and whether it is improving. Dental treatment is needed when a sharp edge, appliance, decay, or infection is responsible.

Arrange dental care if the sore lasts beyond two weeks, keeps returning, enlarges, bleeds easily, feels hard, or is accompanied by a neck lump, numbness, fever, tooth pain, or swelling. Breathing or swallowing difficulty is urgent.

The dentist examines the ulcer and nearby teeth, checks for trauma and infection, and may use a dental X-ray or refer for further assessment if the lesion persists.

Does the appearance suggest trauma, an ulcer, or a draining tooth? Is a nearby tooth infected? What should I monitor, and when would a biopsy or specialist referral be considered?
