Does smoking cause your teeth to turn yellow?

Yes: Cigarette tar can stain teeth yellow, brown or even black. Dental cleanings can remove this very well, but in some instances, it is difficult to remove from between teeth.

Yes: Worse than that, it can progress to brown and even black stains on the teeth, sometimes removable but often if severe not completely removable.

Yes, somtimes worse.: Smoking can leave dark brown stain around the gum line or in between teeth. Then your teeth appear darker or yellowish. I recommend getting your teeth professionally cleaned and whiten. Better yet do not smoke or stop smoking because there are other more serious or life threatening consequences of smoking.
