Gum around tooth is red
Red gum around one tooth is commonly caused by local plaque inflammation, trapped food, trauma, or an infection that needs examination.
The short answer
Red gum around one tooth is commonly caused by local plaque inflammation, trapped food, trauma, or an infection that needs examination. Healthy gingiva is generally firm and coral pink. Inflammation increases blood flow and can make tissue red, swollen, tender, or prone to bleeding, while a root infection may create deeper swelling.
What does healthy gum colour around a tooth look like?
Healthy gingiva is generally firm and coral pink. Inflammation increases blood flow and can make tissue red, swollen, tender, or prone to bleeding, while a root infection may create deeper swelling.
How can you clean red gum around one tooth?
Gently brush along the gumline and clean between teeth with floss or an interdental brush. Do not puncture a swelling or place aspirin directly on the gum; a dentist may probe, test the tooth, and take an X-ray.
When should persistent red gum be checked by a dentist?
Arrange care if redness persists, bleeds repeatedly, or comes with pain, bad taste, pus, swelling, or looseness. Get urgent help for spreading facial swelling, fever, or difficulty swallowing or breathing.
What should you ask about red gum around one tooth?
Could food stuck between teeth cause this? Yes. A sharp food particle or repeated impaction can irritate the gum, but persistent inflammation needs assessment.
