I can see white stuff in the left side of my mouth - after the last teeth on the tooth itself. It also keeps paining on and off and it becomes difficult to eat anything pointy - aloo sev, for eg. I also have a similar thing on the right side of the mouth behind the last teeth on the tooth - mirror position. I'm wondering if it's two wisdom teeth or I'm in early stage of cancer. I did use to smoke - but with a limit of 3 cigarettes per day. Attaching the photo of white stuff as well. Please help me out. Thanks in advance.
