What is the direct answer?
Gum irritation around one tooth can come from trapped plaque or food, trauma, decay, a defective restoration, or infection near the tooth.
What does this question mean?
Inflamed gingiva may be red, swollen, tender, or prone to bleeding. A pocket, partially erupted tooth, or abscess can look similar.
What can you do next?
Brush gently and clean between the teeth with floss or an interdental brush. Do not pick the gum or place aspirin on it.
When should you seek dental care?
Arrange care for persistent bleeding, pus, worsening pain, mobility, or a gum lump. Fever or facial swelling needs prompt assessment.
What should you ask the dentist?
Ask whether the cause is in the gum, tooth, filling, or root and whether imaging is needed.
Frequently asked questions
Why is only one area affected?
A local trigger such as food, plaque, decay, or a root problem can affect one site.
Will salt water cure it?
It may soothe tissue temporarily but cannot remove decay, calculus, or an abscess.
