So i have dipped about a total of 10 times i have now stopped but i have one canker sore and two white dots and a bump in my cheek should i be worried?

Take It Seriously: It's highly unlikely that you've developed a serious oral problem from using spit tobacco just 10 times. However, it's quite possible that you're having a bad reaction to the product. As with any mouth sore, redness, ulcer, etc., it should be checked by a dentist, oral surgeon, or ENT if it persists two weeks or more. It could still be a serious problem, which may/may not be related to the dip.
