Small pus bump on gums
A pus-filled gum bump can be a drainage point from a tooth or gum infection and needs examination even if it is not painful.
The short answer
A dental abscess may drain through a small sinus tract, leaving a pimple-like bump while infection remains in deeper tissue.

How should you keep a pus bump clean before assessment?
Do not pop it; brush gently, keep the area clean, and arrange dental assessment for tests and imaging.
When can a pus bump become an urgent problem?
Seek urgent help if swelling spreads, fever develops, or breathing, swallowing, or mouth opening becomes difficult.
What should your dentist identify as the infection source?
Ask whether the source is the pulp, root tip, gum pocket, or a trapped foreign body and what treatment removes it.
