Immediately: Nicotine and tars begin accumulating on your teeth immediately. It's a gradual process, getting worse with time. Smoke if you want yellow teeth, lung cancer, wrinkled skin, mouth cancer, heart disease, kidney disease, receding gums, stained fingers, and so many other life-altering problems. Tooth discoloration will be the least of your problems.
