Swelling along the lower gums can result from plaque, trapped food, trauma, a tooth abscess, or an erupting tooth and needs examination if it persists.
Why are my gums swollen along the lower jaw?
Swelling along the lower gums can result from plaque, trapped food, trauma, a tooth abscess, or an erupting tooth and needs examination if it persists.
What can cause a lump on the lower gums?
Plaque can inflame the gum margin, while food impaction, a sharp filling, biting injury, periodontal infection, or inflammation around a partially erupted molar can cause a localized lump. A dental abscess may arise from infected pulp or gum tissues.
How can I care for swelling on my lower gums?
Rinse gently with warm water, brush carefully, clean between the teeth, and avoid squeezing the swelling or placing aspirin on the gum. A dentist may examine the tooth, test pulp response, probe the gums, and take an X-ray.
When does lower gum swelling need prompt dental care?
Seek prompt care for increasing swelling, throbbing pain, pus, fever, a bad taste, or difficulty opening the mouth. Emergency help is needed when swelling affects breathing, swallowing, or the eye or neck.
Where exactly is the swelling on my lower jaw?
Is the swelling beside a tooth, under the tongue, or behind the last molar? Could there be decay, a gum pocket, or an erupting wisdom tooth? Will imaging be needed?
Frequently asked questions
Can swollen gums disappear by themselves?
Minor irritation may settle after the trigger is removed, but persistent or painful swelling needs a dental diagnosis.
What will the dentist do first?
The dentist inspects the area, checks nearby teeth and gums, and uses focused tests or imaging to locate the source.
