How is the position of the tooth socket readjusted to keep pace with jaw growth?

• A. New bone at the alveolar crest or base of the socket
• B. Rapid root elongation
• C. Cementum resorption at the base
• D. Reduced alveolar bone remodeling

Answer: (A)

As the jaw grows, the tooth socket keeps pace through remodeling of the surrounding alveolar bone. New bone is formed at the alveolar crest or at the base of the socket, reshaping the socket walls so the tooth remains properly positioned within the expanding jaw. This active bone deposition (with remodeling around the root) adjusts the socket’s position over time. Rapid root elongation isn’t the mechanism for adjusting the socket’s position, and cementum resorption at the base or a general decrease in remodeling wouldn’t achieve the same adaptive readjustment.
