What could a blister-like bump on the lower gum mean?
A blister-like bump on the lower gum may follow trauma or be a drainage point from an infected tooth.
What tissues lie beneath the lower gum near tooth roots?
The lower gum contains soft tissue over the jawbone beside tooth roots. Clear or blood-filled lesions can follow biting, while a recurring pimple-like bump may drain a tooth or gum infection.
What should you avoid doing to a lower gum blister?
Do not pop or burn it. Rinse gently, brush nearby with a soft brush, and note its size, color, recurrence, and relation to a tooth or appliance.
When should a lower gum blister be checked?
Have it examined if it persists, returns, enlarges, bleeds without injury, or comes with toothache, pus, fever, or facial swelling.
Could a lower gum blister come from the tooth root?
Ask whether it is trauma, a gum pocket, or a tooth-root problem and whether an X-ray is needed.
