What causes gum swelling and pain
Gum swelling and pain can come from plaque inflammation, trapped food, trauma, gum infection, or infection inside a tooth.
The short answer
Location and examination findings distinguish inflamed gingiva from a periodontal abscess, pulp infection, or wisdom-tooth inflammation.
How can plaque and deep pockets affect swollen gums?
Plaque inflames the gum margin; a deep pocket may produce pus. A cavity or crack can inflame pulp and form an abscess near the root.
What can you do while a swollen gum is settling?
Clean gently, rinse with lukewarm salt water, and avoid squeezing the swelling. Use medicine only as directed for your health situation.
Which signs make painful gum swelling more urgent?
Prompt care is needed for persistent pain, a gum boil, bad taste, or swelling around one tooth. Fever or facial spread is urgent.
What tests can identify the source of the swelling and pain?
Ask whether the source is gum, pulp, root, or wisdom-tooth tissue, and whether probing, pulp tests, or radiographs are needed.
Frequently asked questions
Can swollen and painful gums have several possible causes?
Yes. Appearance, location, duration, and examination findings help distinguish irritation, infection, trauma, and tooth-related causes.
What should I avoid meanwhile?
Avoid picking, squeezing, harsh products, and any activity that repeatedly irritates the area while arranging care.
