could these be ulcers? She says they're quite painful.Have got her to rinse her mouth with salt water last night but didn't seem to help for very long.(remedy that my own dentist has always relied on for most sore mouth stuff!)Is it common for kids to get mouth ulcers?She sometimes gets them on her gum and doctor did give me some dissolving tablets for her that didn't seem to work either.Was told to make sure she takes vitamin supplements which she already does.
I always got loads of mouth ulcers as a child. I was probably sensitive to certain toothpastes. Zendium is a good toothpaste (not sure for children though). Mouth ulcers should usually go themselves within a few days. Also I think sensitivites to certain fruits could cause it.
Another possibility is oral thrush, that causes white patches in the mouth. often very painful.
If it is mouth ulcers then the best treatment is oral medic. Available from Boots for BOUT £6 iirc. Someone on MN recommended it to me when I had mouth ulcers. Fantastic stuff if very painful for a minute or tw0 - you literally burn the ulcer off with a drop of acid.
I think the packet says not suitable for children, but perhaps ok on a 10yo?
