Gum swollen around crown
Swelling around a crown usually reflects inflamed gum tissue, trapped plaque, a crown-fit problem, or infection beneath the restoration.
The short answer
Swelling around a crown usually reflects inflamed gum tissue, trapped plaque, a crown-fit problem, or infection beneath the restoration. The crown covers the visible tooth, while gum tissue seals around its edge. Redness, bleeding, tenderness, bad taste, or a gum pimple can point to inflammation or a deeper problem.
