<s>[INST] I just pulled a upper back tooth (not wisdom tooth) 3 weeks ago. I am a non smoker and don t use any alkohol for 25 years smoked and drink some before I was 27. My diet is healthy but I have had issues with candida in the past because of antibiotic use. I use very little sugar but I do eat some fruit otherwise whole wheat grains and fruits and vegetables, nuts and seeds and some fish. I have white tounge on the side I pulled the tooth. I have been drinking oregano tea, pau darco, black walnut and taking lots of garlic but it is still there. I took the tooth out because it was infected and he scraped out what was infected under the tooth. I don t want to go on antibiotic which just makes candida come back. Do you know if the white tounge can be caused by fungus or something else? [/INST] Hello, I understand your concern. I am Chat Doctor, infectious disease specialist, answering your concern. White tongue is caused by the fungus infection particularly by yeast infection. I advise you should confirm this white tongue by doing swabbing and performing Grams staining. Yest infection will show up the report Grams positive yeast cells are seen. You can start fluconazole tablet 150 mg two times a day for a week under your doctors' guidance. Please do followup after a week. Avoid antibiotic overuse during this period. Take the complete treatment to get cured. If the remnant of the infection is there is chance of recurrence. So complete treatment will cure this problem.  I will be happy to answer your further concern you can contact me here, or you can contact me on bit.ly/ Chat Doctor.  Thank you, ChatDoctor </s>
