The relation of smoking and other form of tobacco use with dental caries is a subject of debate. Early literature and common belief, it was understood that tobacco helps in reducing dental caries. However, later studies suggest that smokers had poor oral health than non-smokers. The findings contribute to an increased prevalence of dental caries among smokers and other types of tobacco users. But more clinical trials and studies are needed to identify the independent effect of smoking on dental caries as it was found that most people who consumed tobacco also had more sugars and other stuff that was not good for oral health.
