DD is cutting her molars. Twice have I noticed considerable amount of blood from the gum where the tooth has cut through (one of the teeth has 2 corners out, 1 only 1 corner). I have never seen DS's gums bleed when he was teething. This time DD had a piece of ice in her mouth so I assume she bit down on it on the tooth that's cutting through. The way I noticed the blood was that it was smeared on her face and then there was blood covering several teeth. Once she rinsed her mouth, it was clearly coming from the gum over the molar in progress. Should I be concerned?
