Coldsore or mouth ulcer??
Hi, my baby girl fell a few weeks ago and hit her mouth and her teeth punctured two small holes in the bottom lip, I didn't check the top lip. Also a few weeks ago, she managed to take a drink from a cup her cousin drank from, he has coldsores, I'm not 100% he didn't have 1 coming on that day. The 2 punctures on the bottom lip have turned to mouth ulcers, but on her top lip, where I am not sure if she cut or not, there is what looks like another ulcer. My wife is worried it is a Coldsore from the bottle, since we aren't 100% sure if she cut that lip or bot. Attached are photos of both lips, please share your opinion!
