#ask the expert my baby is having oral thrush and doctor suggested oral paint for 10 days after 10 days my doctor suggested to stop and maintain hygiene routine of oral like cleaning for milk residues with finger brush now I observe a white rough patch on his tougue and I showed it doctor she suggested daily cleaning with finger brush that's it.so I'm worried is it anything to worry about rough white patch after usage of oral paint or else it is normal.
