What is the direct answer?
A small hard gum bump may be a normal bony prominence, an eruption-related swelling, or a lesion linked to a tooth, so its location and behavior matter.
What does this question mean?
A torus or other bony prominence may be covered by normal mucosa, but an erupting tooth or root-related swelling can also feel hard.
What can you do next?
Do not file, squeeze, or repeatedly press it. Photograph changes, note duration, and brush gently; examination and radiographs can distinguish bone from a tooth-related lesion.
When should you seek dental care?
Arrange care if it is new, enlarging, painful, ulcerated, draining, or above a decayed tooth; rapid facial swelling or swallowing difficulty is urgent.
What should you ask the dentist?
Ask whether it is bone, an erupting tooth, inflamed tissue, or root-related swelling, and whether imaging or observation is appropriate.
