Can thrush affect places other than your tongue? I have spots that feel rough/irritated on the lining of my cheeks. When I first wake up sometimes there is some white stuff on my gums and near those areas. It's painful when brushing those areas. Also, I have certain spots on my gums that are white and they brush off, leaving my gums bleeding where they were. They keep coming back as white spots and brushing back off. Should I avoid brushing that off or keep doing it?
