** Thanks for contacting with your health concern 1. As I m unable to examine you directly, thus following would be my approach to taking up management of yeast infection: i. As you have already consulted your Doctor and has been provided medicine, so going through the drugs, it probably is a case of Oral Thrush but simultaneously other causes have to excluded like: i. take an opinion of a dentist to exclude any dental anomaly [ill fitting denture] ii. consult an ENT Physician [quick visual examination and strep. test] for any other causes[infective/pathological]. iii. poor oral hygiene iv. dry mouth, addiction [smoking] v. At your age, any underlying medical condition like diabetes, iron deficiency anemia, vitamin B12 deficiency, underactive thyroid. vi. check with VDRL and HIV test to exclude sexually transmitted disease. 2. In the meantime till you get an appointment, make sure: - maintain proper hydration - maintain proper oral hygiene [saline water gargles, and mouthwash after every meal] - stop any addiction since they propagate the formation of white spots in the mouth. PS. even after you have tried all the measures but the spot won t go away or recur, it is best to visit your doctor.
