Hello, I have gone through your query and understand your concern. I suspect these white spots in the inner check and scales in the tongue could be due to fungal infection called Candidiasis or Thrush. Small amounts of the candida fungus are always present in the our mouth and kept in control by the normal bacterial flora. Under the conditions of stress, immuno compromised conditions , Uncontrolled diabetes, these control is altered and the fungal infection flares. Even smoking and steroids also disturbs these control by normal floral bacteria. Physical examination followed by swabbing and microscopic examination is the usual procedure to diagnose the candida infection. You need to take antifungal medication for at least 10 to 14 days to control the infection. In addition, you have to follow oral hygiene practices. If you are a smoker, quit the smoking. Avoid wine, beer, bread and other yeast containing foods. Do not use mouth washes unnecessarily. Hope this helps. Please write back for further queries. Wishing you good health.
