It probably depends on how much of what sort of tobacco product you used, for how long, and how long it's been since you stopped
I know that my dentist could always tell when I was smoking because of the pattern of staining on the
backs of my teeth.
It's a good idea to let your dentist know anyway, since that's who would be most likely to find any abnormality that could be a precancerous
condition, and if he doesn't know you use tobacco, he might not be as careful. And if you did have something like that, you definitely want it found
as early as possible.
