A few days ago my small daughter woke up in so much pain, and she was holding her mouth. She could not eat spicy foods, salty foods, or even sweet foods. She barely let us touch it, but she finally let us look, we saw an ugly canker sore right in between her gums and her lip. :( She was just plain miserable. She didn't want to eat anything or do anything. I've had canker sores before, so I know how much those suckers hurt. I wasn't sure what to do, so I asked the question on our Facebook page,
