Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. It looks like that it is a kind of fungal/ yeast infection. But to confirm the cause I advice you to do microscopic examination from the lesion like Grams staining. This will tell us the exact etiological agent and can help cure us the infection with minimum efforts. But till the result came you xcan take the fluconaze 150 mg tablet once a week. When the result camcyou can change the drug according to the reports. Please also test your self for the HIV and diabetes. This are the common cause for the fungal infection in the oral cavity. So once clear from the above infection you will be readily cured. Please maintain good oral hygiene, hexidine mouthwash can be used. It will help maintianing the good oral hygiene. Avoid spicy foods, bland diet consisting of high protein and carbohydrate can be helpful. Brushing with soft hand after every meal can help to contain this infections. I will be happy to answer your further concern on bit.ly/DrArun. Thank you, Dr Arun Tank Infectious diseases specialist, HCM.
