What is one negative effect of smoking on oral health?

  1. Decreased tooth sensitivity

  2. Increased risk of periodontal disease

  3. Improved recovery from dental procedures

  4. Whitening of teeth

The correct answer is: Increased risk of periodontal disease

Smoking has several detrimental effects on oral health, one of which is the increased risk of periodontal disease. When a person smokes, the harmful chemicals in tobacco can impair blood flow to the gums, leading to reduced immune response and compromised healing. This affects the body’s ability to combat infections, including those caused by bacteria that contribute to periodontal disease. As a result, smokers are more susceptible to gum issues and conditions such as gingivitis and advanced periodontitis. The inflammation, deep pockets between the teeth and gums, and eventual bone loss associated with periodontal disease can lead to tooth mobility or even tooth loss. Furthermore, smoking is known to interfere with the normal function of gum tissue and can hinder the recovery process following dental procedures, making it particularly important for dental professionals to educate smokers about the risks associated with their habits.
