Like cigars and cigarettes, smokeless tobacco products contain at least 28 chemicals that have been shown to increase the risk of oral cancer and cancer of the throat and esophagus.
Smokeless tobacco can irritate our gum tissue, causing it to recede or pull away from your teeth. Once the gum tissue recedes, your teeth roots become exposed creating an increased risk of tooth decay. Exposed roots are also more sensitive to hot and cold or other irritants, making eating and drinking uncomfortable.
In addition, sugars, which often are added to enhance flavor of smokeless tobacco, can increase your risk of tooth decay. Studies have shown that chewing tobacco users were four times more likely than nonusers to develop tooth decay.
