Thanks for writing to us.
I would advise you to visit s dermatologist
nearby so that your oral lesions can be examined and herpes infection or candidal infection can be ruled out.
Right now i would just advise you to maintain oral hygiene
and do betadine mouth rinses
specially after meals. If its an yeast infection oral antifungal
will be required. If its a viral infection oral antiviral will be required.
Hope that helped.
