Swollen gums inner gum swelling causes and evaluation
Swelling inside the gum can come from plaque inflammation, trauma, an erupting tooth, or infection and needs assessment if persistent.
The short answer
A swollen area inside the gum may reflect gingivitis, a trapped food injury, an erupting tooth, a cyst, or an infection from a tooth. The cause is identified by examining the gum and tooth and taking dental radiographs when indicated.
What causes tissue fluid or inflammation around the gum?
Gum swelling is an increase in tissue fluid or inflammatory tissue around the gingiva. A localised lump near one tooth is different from general gum enlargement and can point to a tooth, periodontal pocket, or erupting tooth.
How can you care for swelling inside the gum?
Brush gently around the area, clean nearby spaces carefully, and rinse with plain water after food. Do not puncture the swelling, apply caustic chemicals, or place aspirin directly on the gum.
When should swelling inside the gum be examined?
Arrange prompt dental care for a painful lump, pus, fever, bad taste, facial swelling, or swelling that is enlarging. Emergency help is needed if swelling affects breathing or swallowing.
What should your dentist investigate about the swelling?
Ask whether the swelling is in the gum or arises from the tooth, whether an X-ray is needed, and what treatment addresses the underlying cause.
Frequently asked questions
Can food stuck between teeth cause a lump?
It can irritate the gum locally, although a persistent lump needs a dental examination.
Will antibiotics always fix it?
Antibiotics do not remove decay, a trapped object, or a drainage source; treatment depends on the diagnosis.
