I Have Little White Bumps On The Right Side Of

I have little white bumps on the right side of my lower lip, and a couple on my gums. Next to it I have a dark red sore on my gums. It feels tender and hurts when I apply pressure on it. It also seems like it's inclines in to my gums. What could this be? I'm very worried as I chew Tabacco. Thank you so much for your knowledge in advance
