6. Smoking and cancer
This hard-to-quit habit can increase your chances of developing a life-threatening illness, but the good news is that whether you’ve been a smoker for one year or for ten, quitting smoking can quickly lower your risk of developing oral cancer, lung cancer, heart disease, emphysema and painful lesions in the mouth that do not heal.
If you’re looking for another reason to quit, the threat of a missing tooth might persuade you to pass on purchasing your next pack. In addition to a long list of negative cosmetic effects, including a reduced sense of smell and taste, bad breath, a receding gum line and yellow-tinted teeth, tobacco use is a major cause of tooth loss in adults.
