The short answer
Swelling at the back of the mouth can come from an erupting wisdom tooth, gum infection, trapped food, trauma, or an abscess, so the cause needs examination.
What is the direct answer?
What does this question mean?
The back gum may swell around a partly erupted wisdom tooth, where a flap can trap plaque and food. Other causes include a periodontal pocket, abscess, injury, ulcer, or biting irritation.
What can you do next?
Rinse gently with warm water, keep the area clean, and do not pierce the swelling.
When should you seek dental care?
Arrange prompt care for pain, pus, fever, bad taste, recurrent swelling, or difficulty opening the mouth.
What should you ask the dentist?
Ask whether a wisdom tooth, gum pocket, or neighbouring tooth caused the swelling.
Frequently asked questions
Can a swollen back gum heal on its own?
Minor irritation may settle, but recurrent or painful swelling needs diagnosis.
Should I squeeze the swelling?
No. Squeezing can injure tissue and does not treat a dental infection.
