My gums are swollen at the back
Swelling at the back of the mouth can come from gum inflammation, a partially erupted wisdom tooth, food trapping, or a dental infection.
What can cause swelling at the back of your mouth?
Swelling at the back of the mouth can come from gum inflammation, a partially erupted wisdom tooth, food trapping, or a dental infection.
Why can a partly erupted wisdom tooth inflame the gum?
The tissue behind the last molar may become inflamed when a wisdom tooth is partly covered by a gum flap, called an operculum. Plaque and food can collect there, but decay, a periodontal pocket, or an abscess can produce similar swelling.
How can you care for swollen back gums today?
Rinse gently with warm salt water, clean the area carefully with a soft brush, and choose softer foods while arranging an examination. Do not cut the gum, squeeze swelling, or place aspirin directly on the tissue.
When does swelling at the back of the mouth need urgent care?
Seek urgent dental care for increasing swelling, pus, fever, limited mouth opening, or pain that spreads to the ear or jaw. Facial or neck swelling with breathing or swallowing difficulty is an emergency.
Could a wisdom tooth or gum flap be causing the swelling?
Ask whether a wisdom tooth is involved, whether an X-ray is needed, and whether treatment means cleaning, restoring or removing a tooth, or managing the gum flap.
Frequently asked questions
Can a wisdom tooth cause back-gum swelling?
Yes. A partially erupted wisdom tooth can leave a gum flap where plaque and food collect.
Should I pop a gum swelling?
No. Squeezing can injure tissue and does not remove the source of an abscess.
