This condition usually occurs in children aged between two and 10, but can arise at other ages as well in some cases. It is usually accompanied by a fever, and parents who suspect their child has the condition should contact their doctor to determine whether the treatment requires antibiotics.
  • Geographic tongue is a condition that causes small red islands with borders to appear on the tongue. This gives the tongue a map-like appearance. It is often the case that once the lesions heal on one area of the tongue, they move to another. Geographic tongue is a harmless condition and is not linked with cancer or an infection. Some patients may experience discomfort, and become more sensitive to certain foods.
