Swollen Gums Around a Tooth?
Gums can swell from plaque, trapped food, irritation, decay, or infection; learn what may be causing it and when the tooth needs dental care.
The short answer
Gum swelling is a sign of inflamed gingival tissue, not a diagnosis by itself. Plaque, food impaction, a sharp restoration, hormonal changes, and infection can all produce it.
What does swelling around one tooth usually mean?
Swelling limited to one tooth is more concerning for a local cause such as decay, a gum pocket, an erupting tooth, or an abscess.
How does the gingiva protect and surround each tooth?
The gingiva forms a seal around each tooth and contains blood vessels and connective tissue. Inflammation increases fluid and blood flow in this tissue, making it red, tender, enlarged, or prone to bleeding.
How should you clean around a swollen gum area?
Brush gently along the gumline with fluoride toothpaste and clean between the teeth daily. Rinse away trapped food with water, but do not squeeze a swelling or place caustic substances on it.
When does gum swelling need a dentist’s assessment?
See a dentist if swelling lasts, recurs, bleeds easily, or is associated with bad taste, pus, fever, tooth pain, or looseness. Facial swelling, breathing difficulty, or trouble swallowing is urgent.
Could the swelling be gum disease, decay, or an abscess?
Ask whether the swelling is gingivitis, periodontitis, decay, an erupting tooth, or an abscess. Ask whether you need periodontal probing, a cleaning, or an X-ray.
Frequently asked questions
Can swollen gums heal?
Inflammation caused by plaque can improve after effective cleaning, but swelling from decay or infection needs treatment of the underlying tooth.
Why do gums bleed when swollen?
Inflamed gingiva has fragile blood vessels and can bleed when brushed or probed.
