My 7 year old daughter had some dental work done on Tuesday and last night she started complaining that her throat hurts and  is running a low grade fever since last night off and on today.  Now I just seen red splotches on the roof of her mouth what is going on?
With your query, it would have been better if you had mentioned what dental treatment she got it done. I think what you see on her roof of the mouth are might be ulcers or inflammation due to the materials that have used for the treatment please don't be afraid if this wait 3-4 days if still symptoms persists consult your dentist once again till then for symptomatic relief you can use colonel or McCoppin. Hope thus helps you avoid hot foods for some time
