How can tobacco cause periodontal (gum) disease?
Smoking may be responsible for almost 75% of periodontal diseases among adults. Tobacco products damage your gum tissue by affecting the attachment of bone and soft tissue to your teeth. An example of the effect is receding gums. A receding gum line exposes the tooth roots and increases your risk of developing a sensitivity to hot and cold, or tooth decay in these unprotected areas.
