Yeast infections may be treated by a family practitioner or internist. Women who have vaginal yeast infections may be treated by a gynecologist. Children who have a yeast infection may see their pediatrician. Oral thrush may be treated by a dentist. Severe cases of skin yeast infections may be treated by a dermatologist. If symptoms are severe, you may go to a hospital emergency department where you will be seen by an emergency medicine specialist. Rarely, an infectious-disease and/or a critical-care specialist may help treat the most severe infections.
