What color is the eruption hematoma?

An eruption hematoma presents as a soft, bluish-purple swelling over an erupting tooth because blood has collected beneath the thin gingival mucosa. The pooled venous blood near the surface gives that dark, purple hue, which is the hallmark of a hematoma rather than active inflammation. The swelling reflects a localized disruption around the eruption site and typically resolves on its own as eruption progresses or the hematoma drains. Red would suggest active surface inflammation, while green or yellow would point toward infection with pus or pigment changes—not characteristics of a simple eruption hematoma.
