Swollen top gum
An upper gum swelling is a change in the gingiva above a tooth and its cause may be local gum irritation or infection deeper in the tooth.
The short answer
A swollen upper gum may result from plaque irritation, food trapped between teeth, trauma, a gum abscess or infection from an upper tooth.. A dentist checks the pocket, tooth surface, bite and pulp, then may take an X-ray to distinguish gum swelling from a root-related abscess.
How can a dentist tell whether the swelling is tooth-related?

What can you do safely for a swollen upper gum?
Clean gently with a soft brush and interdental aid, rinse with warm water, and do not puncture or squeeze the lump.
When does a swollen upper gum need prompt care?
Arrange prompt care if the swelling is painful, enlarging, recurrent or associated with bad taste, fever or facial swelling.
What should you ask about the source of the gum swelling?
Ask whether the swelling begins in the gum or tooth, whether drainage is present, and what treatment removes the source.
Frequently asked questions
What is the most useful first step?
Describe the exact location, timing and triggers of the symptom so the dentist can target the examination.
Can home care replace an examination?
Home care can reduce irritation or discomfort temporarily, but it cannot correct a structural problem or remove an infection.
