My gum is swollen over my tooth
A swollen gum over one tooth can come from trapped plaque, a gum pocket, food impaction, or infection around the tooth.
The short answer
A swollen gum over one tooth needs an examination because the cause may be local gum inflammation, decay-related infection, or an erupting tooth.
What does focal swelling over a tooth mean?
This is focal gingival swelling beside or partly covering one tooth. Local plaque, a gum pocket, food trapped under the gum, decay-related infection, or an erupting tooth can produce it.
How should I care for swelling over a tooth?
Rinse gently with warm water, brush softly around the area, and avoid squeezing the swelling or placing aspirin on the gum.
When does swelling over a tooth need prompt care?
Arrange dental care promptly for worsening pain, pus, fever, facial swelling, trouble swallowing, or difficulty opening the mouth.
Could this swelling be an abscess or erupting tooth?
Could the swelling be an abscess, a gum pocket, food trapped under the gum, or an erupting tooth?
