Which of the following best describes the goal of periodontal surgery?

The goal of periodontal surgery focuses on restoring periodontal structures and health. This involves addressing the factors that contribute to periodontal disease, such as inflammation, infection, and the loss of supporting structures around the teeth. The primary objectives of periodontal surgery include reducing pocket depths, regenerating lost bone and tissue, and improving overall periodontal function. By restoring health in these areas, the intention is to not only preserve the natural teeth but also to promote better oral health and potentially prevent further periodontal issues.

The other options, while related to dentistry, do not capture the main aim of periodontal surgery. For instance, removing all teeth affected by periodontal disease is an extreme and often unnecessary approach, as the goal is to save teeth whenever possible. Altering a patient's bite for cosmetic reasons usually pertains more to orthodontics or cosmetic dentistry rather than the primary health-focused aim of periodontal surgery. Similarly, while enhancing a patient’s smile can be a positive outcome, it is not the primary objective of periodontal surgery, which is to ensure the periodontal tissues are healthy and functional.
