The little flap of tissue that connects from the inside of the lip
/mouth on the bottom to the gum
is also inflammed and very sore
. There arent any ulcers or patches that I can see and he just recently started to complain about 2-3 days ago. My son goes to the dentist regularly, has not had any issues, and we help him bursh his teeth on a regular basis. The top gums and sides seem fine. He does not have a fever, sore throat, or any rash on his body, hands, or feet.
