Snuff Users Have Fewer Dental Caries.
It is a myth that snus (Swedish snuff) users today have fewer dental caries. On the contrary, some types of nicotine-free snus contain both carbohydrates and starch that increase the risk of cavities.
A common notion is that people who use nicotine-containing snus have fewer cavities. But that notion is a myth. A fact proven by Lena Hellqvist, a doctoral student at Sahlgrenska Academy at the University of Gothenburg and a member of staff at Karlstad University, who studied oral health among snus users for her thesis.
