Where should suturing start when closing extraction sites?

• A. At the corners
• B. In the center
• C. On the buccal margin
• D. At the tooth apex

Answer: (A)

When closing an extraction site, begin by placing the first suture at the corners of the wound. Starting at the corners anchors both sides of the mucosa and brings the buccal and lingual/palatal margins together evenly, distributing tension across the entire edge. This promotes a smooth, symmetrical edge and helps achieve a secure, primary closure over the socket. Starting in the center can cause uneven pull, puckering, or gaps at the margins, while starting solely at the buccal margin or at the tooth apex doesn’t control the opposite edge or provide balanced approximation.
