I have a sore on my upper gum
An upper-gum sore may be trauma, an ulcer, a draining tooth infection, or irritation, so its appearance and duration matter.
What could a sore on the upper gum indicate?
An upper-gum sore may be trauma, an ulcer, a draining tooth infection, or irritation, so its appearance and duration matter.
What different types of upper-gum sore are possible?
A sore can be a shallow ulcer, a cut from food or brushing, a burn, a blister, or a small swelling beside a tooth. A pimple-like bump that drains may come from infection in the tooth or gum rather than a simple ulcer.
How can you soothe and protect an upper-gum sore?
Rinse gently with water, avoid spicy or sharp foods, and use a soft toothbrush around the area. Do not pop, scrape, or apply household chemicals to the sore; record its size, colour, pain, and any tooth sensitivity.
When should an upper-gum sore be checked?
See a dentist if the sore persists, returns, enlarges, bleeds easily, or is associated with tooth pain, swelling, pus, fever, or a neck lump. Urgent care is needed for facial swelling or difficulty swallowing or breathing.
What should you ask about the sore and nearby tooth?
Ask whether the lesion is an ulcer, trauma, gum abscess, or tooth abscess, and whether the nearby tooth needs pulp testing or an x-ray. Ask what treatment and mouth-care changes will help it heal.
Frequently asked questions
Can a gum sore be an abscess?
Yes. A tender pimple-like swelling beside a tooth can be a drainage point from a dental infection and needs examination.
When does a mouth sore need checking?
Persistent, recurrent, enlarging, or unusual sores should be assessed, especially with pain, swelling, or fever.
