Overconsumption of Tobacco
Overconsumption of tobacco can cause yellow teeth. Smoking, chewing, or sucking on tobacco products can cause yellowing of the teeth. In addition to the yellow stains, tobacco use also causes bad breath and an increased risk of gum disease and tooth loss.
The chemicals in tobacco can change the color of your teeth over time. They can also harden the enamel on your teeth, making them more susceptible to decay. Studies have found that smokers are twice as likely to lose their teeth as non-smokers by age 35.
Tobacco use can cause bad breath. This is because cigarette tar adheres to the teeth, tongue, and gums. When it dries, it becomes a dark brownish-yellow color that can leave a smoker’s mouth smelling foul. Other symptoms of bad breath related to smoking include dry mouth, food being left behind between the teeth, and a lingering odor.
