Smoking is a significant risk factor for developing oral diseases, including gum disease, tooth decay, and oral cancer. It can also exacerbate existing oral health problems and complicate dental treatments. Therefore, dentists routinely ask patients about their smoking habits to assess their risk for oral health issues and to provide appropriate preventive care.
Smoking damages the immune system, making it more difficult for the body to fight off infection and heal from injuries. In the mouth, this can lead to gum disease, which is a major cause of tooth loss. Smoking also reduces the flow of saliva, which helps to protect the teeth from decay. Additionally, the chemicals in cigarettes can damage the tooth enamel, making it more susceptible to cavities.
