Inflammation of gums around one tooth
Inflammation around one tooth can come from trapped plaque, trauma, an erupting tooth, or infection and needs a targeted examination.
The short answer
Inflammation around one tooth can result from plaque, trapped food, trauma, an erupting tooth, a gum pocket, or infection near the tooth; the cause determines treatment. A cold compress may ease discomfort, but it cannot remove bacteria or drain an abscess.
Why can plaque make one gum margin red and swollen?
The gum margin may become red, swollen, tender, or bleed when plaque irritates it. If swelling is deeper, a periodontal pocket, cracked tooth, decayed pulp, or infection at the root may be involved even when only one area is visible.
How can you clean between the affected tooth and its neighbour?
Brush gently along the gumline and clean between the affected tooth and its neighbour with floss or an interdental brush if it can pass without force. Rinse with water after meals, avoid picking at the swelling, and do not place aspirin or chemicals on the gum.
When does inflammation around one tooth need an appointment?
Arrange an appointment if the inflammation lasts, bleeds repeatedly, returns, or is joined by pain, pus, bad taste, looseness, or pain on biting. Seek urgent help for fever, facial swelling, or difficulty swallowing or breathing.
Is the problem at the gum, pocket, erupting tooth, or root?
Ask whether the problem is at the gum margin, inside a periodontal pocket, around an erupting tooth, or at the root. Ask whether you need professional cleaning, a filling, root canal treatment, drainage, or another procedure.
Frequently asked questions
Can gum inflammation around one tooth go away?
Mild irritation may improve after careful cleaning, but persistent or recurrent swelling needs an examination for a deeper cause.
Why does one tooth area bleed?
Plaque, a trapped food particle, trauma, or a local gum pocket can make that area inflamed and prone to bleeding.
