I have just recently noticed a hard lump/bump/pimple type spot inside my mouth, located opposite my front tooth line on the inside of my lip. It is almost located where the gums meet in between the lips and teeth. It is pressure sensitive, like when I smile. The coloring is pink with white inside it, and it does not seem superficial. It seems to come from somewhere, but that is the spot that is hard. I am concerned about this new spot, but I have limited funds and no insurance. Any advice about what this could be would be appreciated.
