Mouth diseases

Smoking stains teeth, even within just a few years. Some or most of this stain can be removed in the early years of smoking, but as time goes on, staining spreads deeper into creavices in the enamel and is much more difficult to remove. Eventually, the teeth become permanently stained.

Chewing tobacco is no safer than cigarettes as many of the same carcinogens exist in both, putting the user at much higher risk of oral cancers. Spit tobacco also contains abrasives, salt, and sugar, none of which are good for you.
