We demonstrated the impact of smoking history and current smoking status on tooth loss in a population of 46-year-old adults and found that the probability of losing teeth increases in an exposure-dependent manner commensurate with smoking intensity and duration. Conversely, those who had stopped smoking or smoked only occasionally were at lower risk for losing teeth than those who smoked daily. Thus, smoking cessation and quitting smoking among adults should be a priority.
