The short answer
Swelling behind the lower front teeth can come from plaque and calculus, gum infection, trauma, an erupting tooth, or a local lump, so the area should be examined if it persists.
What tissue lies behind the lower front teeth?
The tissue behind the lower incisors is attached gum over the inner surfaces of the teeth, close to salivary-duct openings and the floor of the mouth.
How can you care for swelling behind the lower teeth?
Brush gently around the area, clean between the teeth, avoid squeezing the swelling, and rinse with plain water while arranging an examination.
When is swelling behind the lower teeth urgent?
Get urgent help for rapidly increasing swelling, fever, pus, facial swelling, severe pain, or difficulty opening the mouth, swallowing, or breathing.
What tests may identify swelling behind the lower teeth?
Ask whether the swelling is gingival, dental, salivary, or soft-tissue in origin, and whether a periodontal measurement, dental X-ray, or other test is needed.
Frequently asked questions
Can swollen gum behind the teeth heal alone?
Minor irritation may settle after the trigger is removed, but ongoing swelling can indicate calculus, infection, or another lesion requiring diagnosis.
Why is this area prone to buildup?
Saliva enters the mouth near the lower front teeth, and plaque can harden there when it is not removed during daily cleaning.
