DD8 has a pea shaped lump on her gum which over the last 24 hours has got bigger. It's flesh coloured although the skin at the top of her gum is dark red. She says it hurts when you touch it (it's soft to touch) and sometimes on it's own. I will of course try and get an appointment tommorow with dentist but just wondered what it is and what to expect at the dentist as I have no experience. Have given her Nurofen. Please help.
