The main components in cigarettes are chemicals known as tar and nicotine. Regular cigarette smoking will eventually cause tar stains and residual buildup on your teeth, which is why many cigarette smokers have yellow-stained teeth. Generally, a higher ratio of tar and nicotine will cause more stains on your teeth. Although not smoking altogether is the only method to avoid tar stains, you can take steps to remove tar stains and get more healthy-looking teeth.
