What is the direct answer?

A blister-like bump on the lower gum may follow trauma or be a drainage point from an infected tooth.

What does this question mean?

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 can you do next?

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 you seek dental care?

Have it examined if it persists, returns, enlarges, bleeds without injury, or comes with toothache, pus, fever, or facial swelling.

What should you ask the dentist?

Ask whether it is trauma, a gum pocket, or a tooth-root problem and whether an X-ray is needed.
