Hi Anne, Sometimes sores in the mouth can be thrush. Adults don't usually get the white-coated tongue appearance that we see in babies. They can have just a sore tongue, or throat, or ulcers. Cracks in the corner of the mouth (angular cheilitis) are not uncommon also. Lisa Amir GP / IBCLC in Melbourne, Australia
