Which of the following is not listed as a lifestyle factor affecting oral health?

• A. Tobacco use
• B. Excessive alcohol use
• C. Poor dietary choices
• D. Regular exercise

Answer: (D)

Lifestyle choices shape how likely you are to develop caries, gum disease, or mucosal issues. Tobacco use directly harms oral tissues, raises the risk of periodontal disease and oral cancer, and causes staining and bad breath. Excessive alcohol can lower saliva flow and irritate the mucosa, and it’s often linked with higher cancer risk in the mouth, especially when combined with other factors. Poor dietary choices—especially frequent sugar intake and acidic foods or drinks—fuel caries development and can contribute to enamel wear. Regular exercise, while excellent for overall health, does not have a direct adverse effect on the teeth or gums and isn’t listed as a lifestyle factor affecting oral health. That’s why regular exercise is the best answer.
