Inflamed gum around tooth
An inflamed gum around one tooth may reflect plaque, trapped food, trauma, decay, or infection near the tooth.
The short answer
An inflamed gum around one tooth may reflect plaque, trapped food, trauma, decay, or infection near the tooth. Gentle cleaning can help, but swelling or pain needs a dental examination to identify the source.
How does plaque irritate the gum around a tooth?
The gingiva can become red, puffy, tender, or prone to bleeding when plaque irritates its margin. A single affected site also raises the possibility of food impacted between teeth, a rough filling, a cracked tooth, a cavity, or an abscess draining beside the root.
How can you gently clean an inflamed gum around a tooth?
Clean the tooth gently with a soft brush and use floss or an interdental brush to remove debris from both sides. Choose soft foods temporarily and do not squeeze, pierce, or apply caustic substances to the swelling.
Which symptoms mean an inflamed gum needs prompt care?
Arrange care promptly for increasing pain, pus, a bad taste, fever, a loose tooth, or swelling spreading into the cheek. Emergency help is needed if mouth swelling affects swallowing, breathing, or opening the eye.
Is the gum pocket, tooth, filling, or root causing the problem?
Ask whether the gum pocket, tooth surface, filling, or root is responsible. Ask if the examination should include probing, a bite test, cleaning, or a dental X-ray, and what treatment addresses the cause.
Frequently asked questions
Can an inflamed gum settle on its own?
Minor irritation may improve after debris is removed, but recurring or painful swelling needs diagnosis.
Does a gum swelling always mean an abscess?
No. Plaque, trauma, trapped food, and a rough restoration can also cause local swelling.
