Thank you for your query.
I suggest that you stop using Traimcinolone cream and observe. Make your daughter rinse her mouth with Listerine
mouth wash and observe. In case the white patches do not disappear then clotrimoxazole lotion may be applied on the white patches as treatment of oral thrush
I hope I have answered your query to your satisfaction.
Wishing your daughter all the best.
