hi, my 6 year old daughter has little white spots on the tip of her tongue and a couple further back. She complained her tongue was sore 2 days ago, i looked and saw nothing, thought she must of bit her tongue.... didnt seem to bother her since, until tonite and she was upset, had a good look and saw the pimply white spots. She is sleeping away fine now, what could this be and are antibiotics the only way to treat it?
