Hello Dr. Actually the opening of patotid papilla on inside of my cheeks has become prominant since last 3-4 mnths. It's more visible on right cheek than left. I dont feel any pain or anything with it. Don't hv any problem in eating or drinking. But sometimes I feel some irritating pain on right side. I saw these openings on my friend cheek but they are not so visible. Is there anything to worry about or its normal?? Your words would be valuable for me. Thanks in advance
