What is the small red lump on my gum between 2 teeth?
If it’s between the two front teeth on the top – you’ve probably just irritated the area there, it’s quite common & will heal quickly. If it’s somewhere else, it’s probably just an ulcer (a sharp piece of food probably stabbed it or something). Get it checked out anyway, but I don’t think it’s anything serious. P.S: – I don’t know how old you are, but my wisdom teeth are just coming in, the first one caused my gum to swell so much that I couldn’t close my mouth.
