Flat red spot on 3 years old hard palate

About two weeks I noticed my 3 and half year old daughter had two flat red spots on her hard palate. I didn't think two much about it, I just assumed she injured it somehow and it would go away. I just kept an eye on it and its now gotten larger and become one large spot. I have asked her if it hurts it bothers her and she doesn't act like it does. I have taken her to the doctor and the dentist and both don't seemed very concerned they just said its inflammation. I am concerns because it doesn't seem to be resolving at all. She has asthma and is on pulmicort and albuterol Dailey through a nebulizer. Also a few weeks ago the doctor have her a rescue inhaler without a chamber of albuterol which she has used a few different times but I didn't rinse her mouth out afterwards with any of the treatments so I am wandering if this could be Erythematous candidiasis. I just need some answers because my doctor and dentist are unable to provider any answers to me. Thanks.
