What we are talking about replacing is the smokeless tobacco known as tobacco chew or snuffs and commercialy known as Copenhagen, Kodiak, Skoal and a host of other names around the world. Scandinavian countries have a relatively high use also. The U.S. National Institute of Health has found that smokeless tobacco contains more nicotine. There are many more minor problems dipping snuff. For instance, it stains teeth, creates bad breath, and causes loss of taste.
More serious damage is caused to the teeth and gums.
Sugar in smokeless tobacco can cause serious tooth decay. The grit can wear down enamel. The strong chemicals in the snuff can cause the gums to pull away from the teeth where the quid is held and gum damage is difficult to repair and can result in tooth loss. The most serious problems are white patches and sores inside the mouth. Leathery white patches develop where the quid comes in contact with the cheek and gum.
