Tooth Yellowing: Smoking can cause yellowing and discolouration of the teeth. The chemicals in cigarette smoke discolour the tooth enamel, resulting in an aesthetically unpleasant appearance.
Gum Diseases: Smoking may increase the risk of developing gum diseases (gingivitis and periodontitis). Gingivitis and bleeding are more common in smokers and this may lead to tooth loss in the future.
Tooth Decay: Smoking can disrupt the pH balance in the mouth and increase acid production, which can increase the risk of tooth decay. In addition, the amount of bacteria in the mouth and caries formation may be higher in smokers.
