So i have noticed a whitish spot on some pimple(yellow circle in picture one) in my left inner cheek, and also the area near the end turning brownish(red circle), why is it happening? M i having fungal infection? I have wisdom tooth on left side since a year, this never happened.. 2nd pic is attached image of right inner cheek. My right buccal mucosa also has brownish spot, I dont smoke, eat tobaco or drink much.. In right side both the wisdom tooth are impacted hence dentist said to extract them which i will. But m worried about these brown spots, it initially started in right side, now same happening in left side too.. Please advice
