What is the primary purpose of socket preservation after extraction?

• A. Maintain ridge dimensions after extraction for future prosthetics or implants
• B. Promote rapid eruption of adjacent teeth
• C. Increase saliva production
• D. Stop all bleeding permanently

Answer: (A)

Maintaining the shape and size of the jawbone (the alveolar ridge) after a tooth is removed is the main idea here. When a tooth is extracted, the surrounding bone naturally resorbs, especially the outer wall, which can shrink the ridge horizontally and vertically. Socket preservation uses graft material and sometimes a membrane to support bone healing and limit this resorption, helping keep the ridge wide and tall enough for future prosthetics or implants. This leads to better aesthetics, easier implant placement, and reduces the need for additional ridge augmentation later. It’s not about triggering eruption of adjacent teeth, increasing saliva, or stopping bleeding permanently; those aren’t the goals of socket preservation.
